Sebastien de Montessus, President and CEO, commented: “2022 was another successful year for Endeavour in which we delivered against all our objectives and met guidance for the 10th consecutive year.

We produced 1.4Moz of gold over the year, reaching the top end of our guidance. We are particularly pleased to have achieved our all-in sustaining cost guidance of below $930/oz, despite the inflationary pressures impacting the industry, as a result of our strong production performance and optimisation initiatives.

This operational performance resulted in robust cash flow generation which has allowed us to fund both our growth and shareholder returns programme while also improving our financial position. We are excited by our growth prospects given construction activities for the Sabodala-Massawa expansion and the Lafigué greenfield project are progressing well, with both on budget and on track for first production in 2024. Moreover, our exploration programme was very successful with the discovery of the promising Tanda-Iguela deposit, which has the potential to be another cornerstone asset for the Company.

During 2022, we continued to deliver on our commitment to generate attractive shareholder returns with approximately $100 million of share buybacks completed and $200 million of dividends announced for the year, which is well above our $150 million minimum commitment. This represents a return to shareholders of $212/oz of gold produced in the form of dividends and buybacks.

With a strengthened management team, we look forward to further success in 2023, with our guidance demonstrating confidence in our continued ability to deliver against our strategic objectives for the benefit of all our stakeholders.”

MANAGEMENT CHANGES

As part of its continuous efforts to optimise the business and deliver Endeavour's next growth phase, the Company is pleased to announce several changes to its senior management team.

In March 2023, Joanna Pearson will be stepping down as EVP and Chief Financial Officer ("CFO") and will be replaced by Guy Young. Mr. Young will join Endeavour from Vesuvius plc, the FTSE250 molten metal engineering and technology group, where he has been Chief Financial Officer since 2015. Prior to this, he served as Chief Financial Officer of Tarmac and subsequently Lafarge Tarmac, the British building materials company. He previously held a number of senior financial and business development positions at Anglo-American plc. In addition, Martino De Ciccio, currently Vice President of Strategy and Investor Relations, will assume the newly created role of Deputy CFO, maintaining his focus on investor relations.

Further changes have also been made to the Company's senior team to reflect the company's evolution over the past years. The Executive Committee will now be composed of ten members comprised of Sebastien de Montessus as CEO, Mark Morcombe as Chief Operating Officer, Guy Young as CFO, Morgan Carroll as EVP Corporate Finance and General Counsel, Pascal Bernasconi as EVP Public Affairs and Security, David Dragone as EVP HR and Communications who recently joined the Group, Martin White as EVP Projects (previously General Manager at Endeavour's Mana mine), Jono Lawrence as EVP Exploration (previously SVP Exploration), Guenole Pichevin as EVP Strategy and Business Development (previously VP Strategy and Business Development), and Djaria Traore as EVP ESG and Supply Chain (previously VP Supply Chain).

In accordance with Endeavour’s succession planning strategy, Jono Lawrence replaces Patrick Bouisset who retired on 31 December 2022. Subject to shareholders approval at the next Annual General Meeting in May 2023, Mr. Bouisset is expected to be appointed to the Endeavour Board as a Non-Executive Director and a La Mancha representative, replacing Jim Askew who has decided to retire and will not therefore stand for re-election. The Company confirms that there is no further information to be disclosed in respect of Mr. Bouisset’s appointment under the FCA’s Listing Rule 9.6.13.

SHAREHOLDER RETURNS PROGRAMME

• Endeavour is pleased to announce its H2-2022 interim dividend of $100 million or approximately $0.41 per share based on its current issued share capital. As such, the total dividend amounts to $200 million or approximately $0.81 per share for FY-2022, which represents $50 million or 33% more than the minimum dividend commitment for the year, reiterating Endeavour's strong commitment to paying supplemental shareholder returns.
• The ex-dividend date for the H2-2022 interim dividend will be 23 February 2023 and the record date will be 24 February 2023. The dividend will be paid on or about 28 March 2023 (the “Payment Date”). Shareholders of shares traded on the Toronto Stock Exchange will receive dividends in Canadian Dollars (“CAD”), but can elect to receive United States Dollars (“USD”). Shareholders of shares traded on the London Stock Exchange will receive dividends in USD, but can elect to receive Pounds Sterling (“GBP”). Currency elections and elections under the Company's dividend reinvestment plan ("DRIP") must be made by shareholders prior to 17:00 GMT on 7 March 2023. Dividends will be paid in the default or elected currency on the Payment Date, at the prevailing USD:CAD and USD:GBP exchange rates on 13 March 2022. This dividend does not qualify as an “eligible dividend” for Canadian income tax purposes. The tax consequences of the dividend will be dependent on the particular circumstances of a shareholder.
• Shareholder returns are being supplemented through the Company’s share buyback programme. A total of $98.7 million, or 4.6 million shares were repurchased during FY-2022, of which $24.2 million or 1.2 million shares were repurchased in Q4-2022.
• As shown in Table 3 below, Endeavour returned $299 million to shareholders for FY-2022 through dividends and share buybacks, equivalent to $212 per ounce produced. Since the launch of the Company’s shareholder returns programme in early 2021, a cumulative $637 million (including the upcoming H2-2022 dividend) has been delivered to shareholders in the form of dividends and share buybacks.

• At 31 December 2022, Endeavour’s available sources of financing and liquidity remained strong at approximately $1.53 billion, which included approximately $951 million from its current cash position and $575 million in undrawn funds from its revolving credit facility, which has been upsized from $500 million to $575 million to provide additional liquidity headroom during the Company's ongoing construction phase. As a result, the Company has significant financial flexibility to settle the principal amount of its outstanding convertible bond in cash at its maturity on 15 February 2023.

2022 OPERATIONAL PERFORMANCE OVERVIEW         

• FY-2022 production from continuing operations amounted to 1,400koz, achieving the top end of the guided 1,315-1,400koz range while all-in sustaining costs ("AISC") amounted to ~$928/oz, achieving the guided $880-930/oz range in spite of industry-wide inflationary pressures. The production out-performance is mainly due to the Houndé and Ity mines which benefitted from higher than planned throughput, and the Mana mine where higher than expected open pit mining tonnages were extracted from the Wona open pit prior to its depletion. Inflationary pressures on costs were partially offset by favourable foreign exchange movements as the Euro declined against the Dollar as well as group-wide optimisation initiatives.
• FY-2022 production from continuing operations decreased by 36koz or 3% from 1,436koz in FY-2021 to 1,400koz in FY-2022 due to lower production at Boungou, Mana and Wahgnion as a result of mining and processing of lower grade ore. AISC from continuing operations increased, in line with guidance, from $882/oz in FY-2021 to $928/oz in FY-2022.
• The Group’s realised gold price from continuing operations, excluding the impact of realised gains on gold hedges and inclusive of the Sabodala-Massawa gold stream, was $1,742/oz and $1,792/oz for Q4-2022 and FY-2022 respectively. Including the impact of the gold hedges, the Group's realised gold price from continuing operations was $1,758/oz and $1,807/oz for Q4-2022 and FY-2022 respectively.

¹All Q4-2022 and FY-2022 numbers are preliminary and reflect Endeavour's expected results as at the date of this press release.

Q4-2022 vs Q3-2022 Insights

• Production decreased due to lower tonnes milled and a slightly lower recovery rate, while processed grades remained flat.
  • Total ore tonnes mined increased due to greater ore availability and lower stripping in the West Pit compared to the prior quarter.
  • Tonnes milled decreased due to downtime experienced during the quarter due to the previously disclosed supply chain challenges in the quarter.
  • Average grade processed remained flat compared to the prior quarter as a decrease in the average grade of mined ore was offset by reduced reliance on lower grade stockpiles in the mill feed.
  • Recovery rates decreased slightly due in part to reduced volumes in the processing circuit.
• AISC decreased due to lower mining unit costs driven by reduced haulage and blasting, partially offset by lower ounces sold during the quarter.

FY-2022 Performance

• FY-2022 production totalled 116koz, which inline with the previously disclosed outlook, stands below the guided 130-140koz range mainly due to lower than scheduled mining activities, which limited access to higher grade ore, as a result of supply chain delays. FY-2022 AISC amounted to approximately $1,064/oz, which is above the guided $900-1,000/oz range due to the lower than expected production, higher fuel prices and increased security costs.
• FY-2022 production decreased from 174koz in FY-2021 to 116koz in FY-2022 due to the impact of lower grade material available in FY-2022 due to supply chain delays. FY-2022 AISC increased from $801/oz in FY-2021 to $1,064/oz in FY-2022 due to the lower grades processed, and fuel, consumable and security cost increases.

2023 Outlook

• Boungou is expected to produce between 115-125koz in FY-2023 at an AISC of between $985-1,075/oz.
• Mining activities in H1-2023 are expected to focus on waste stripping at the West Flank pit and ore mining in the West pit phase 3. In H2-2023, greater ore volumes are expected to be sourced from the West Flank pit. Mill throughput is expected to decrease slightly while grades are expected to improve year over year. Production is expected to be weighted towards H2-2023 as higher grades will be accessed from the West Flank pit in H2-2023 after waste stripping activities wind down.
• Sustaining capital expenditure is expected to decrease from approximately $6.6 million in FY-2022 to $5.0 million in FY-2023, relating mainly to waste stripping, plant maintenance and fuel storage capacity increases.
• Non-sustaining capital expenditure is expected to increase from approximately $27.5 million in FY-2022 to $30.0 million in FY-2023, relating primarily to significant waste stripping activity at the West Flank pit in H1-2023.

¹All Q4-2022 and FY-2022 numbers are preliminary and reflect Endeavour's expected results as at the date of this press release.

Q4-2022 vs Q3-2022 Insights

• Production decreased due to lower processed grades, which was slightly offset by higher mill throughput, while recovery rates remained flat.
  • Tonnes of ore mined increased as higher volumes mined in the Kari West and Vindaloo Main pits offset lower volumes from the Kari Pump pit, where stripping activities have continued. Total tonnes mined increased due to higher utilisation of the mining fleet following the end of the wet season.
  • Tonnes milled increased as there was a higher proportion of softer ore from Kari West in the mill feed enabling higher throughput rates.
  • Processed grades decreased, as per the outlook previously disclosed, due to less high grade oxide ore sourced from the Kari Pump pit given the increased focus on stripping activities.
• AISC increased mainly due to increased mining volumes and lower production due to lower average grade in the ore blend in addition to higher unit milling costs.

FY-2022 Performance

• FY-2022 production totalled 295koz, which inline with the previously disclosed outlook, exceeded the guided 260-275koz range, due to higher than scheduled volumes of high grade ore sourced from the Kari area and better mill performance following optimisation initiatives. FY-2022 AISC amounted to approximately $809/oz, which is below the guided $875-925/oz range due to the benefit of the higher than expected production.
• FY-2022 production remained consistent with FY-2021 as increased mill throughput, driven by efficiency improvements, and improved recoveries associated with the high-grade ore sourced from the Kari Pump pit offset a lower average grade milled. FY-2022 AISC decreased from $843/oz in FY-2021 to approximately $809/oz in FY-2022 due to lower waste mining volumes.

2023 Outlook

• Houndé is expected to produce between 270-285koz in FY-2023 at AISC of $850-925/oz.
• Mining activities during the year will focus on the Vindaloo Main, Kari Pump and Kari West pits. In H1-2023, ore is expected to primarily be mined from the Kari West pit, while significant waste stripping is underway at the Kari Pump and Vindaloo Main pits. In H2-2023, greater ore volumes are expected to be mined from the Kari Pump and Vindaloo Main pits following the waste stripping in H1-2023, with Kari West continuing to provide supplemental feed. Production for the year is expected to be weighted towards H2-2023 as the waste stripping activities in H1-2023 are expected to provide access to higher grade ore sources at both the Kari Pump and Vindaloo Main pits in the second half of the year. Throughput and recoveries are expected to be slightly lower in FY-2023 compared to FY-2022 due to a greater proportion of harder fresh ore in the blend.
• Sustaining capital expenditure is expected to increase from $27.4 million in FY-2022 to approximately $40.0 million in FY-2023, relating mainly to waste stripping, fleet re-builds and plant equipment replacements and upgrades.
• Non-sustaining capital expenditure is expected to decrease from $39.2 million in FY-2022 to approximately $35.0 million in FY-2023, and primarily relates to waste stripping activities and stage 8 and 9 of the TSF1 embankment raise.

¹All Q4-2022 and FY-2022 numbers are preliminary and reflect Endeavour's expected results as at the date of this press release.

Q4-2022 vs Q3-2022 Insights

• Production remained flat as lower processed grades were offset by higher throughput, while recoveries remained consistent.
  • Tonnes of ore mined and total tonnes mined increased due to increased mining rates at the Ity and Walter pits as well as increased tonnages mined from the historic stockpiles, which was partially offset by reduced mining at the Le Plaque pit.
  • Tonnes milled increased as a higher proportion of softer oxide ore from the historic heap leach stockpiles was fed through the surge bin feeder, while the previous quarter was impacted by the wet season.
  • Processed grades decreased as a lower proportion of high grade material from Le Plaque was processed.
• AISC increased due to lower grade ore processed, which was partially offset by slightly lower unit mining and processing costs.

FY-2022 Performance

• FY-2022 production totalled 313koz, which in accordance with the previously disclosed outlook, was above the guided 255-270koz range mainly due to higher than expected grades, higher recoveries associated with less processing of transitional material from Daapleu, and improved processing plant performance from increased throughput and use of the surge bin. FY-2022 AISC amounted to approximately $812/oz, which was below the guided $850-900/oz range mainly due to the higher than expected production and grades.
• FY-2022 production increased from 272koz in FY-2021 to 313koz in FY-2022 due to an increase in throughput rates from improvements in plant operating and maintenance strategies, continued use of the surge bin providing supplemental oxide ore to the mill feed, higher average processed grades due to higher portions of high grade material from Le Plaque in the mill feed and higher recoveries due to a lower portion of fresh material from Daapleu. FY-2022 AISC decreased from $836/oz in FY-2021 to approximately $812/oz in FY-2022, driven largely by the increased production during the period.

2023 Outlook

• Ity is expected to produce between 285-300koz in FY-2023 at an AISC of between $840-915/oz.
• For FY-2023, ore is expected to be sourced from the Ity, Bakatouo, Le Plaque and Walter pits, supplemented by historical heap leach stockpiles. Ore tonnes processed for FY-2023 are expected to remain consistent with the prior period. Grades are expected to decline compared to the prior year due to the cessation of ore mining at the higher grade Daapleu open pit in mid-2022, while recoveries are expected to increase as no Daapleu fresh material is expected in the mill feed for FY-2023.
• Sustaining capital expenditure is expected to increase from $13.4 million in FY-2022 to $25.0 million in FY-2023 and is primarily related to waste stripping, de-watering borehole drilling and capital spares.
• Non-sustaining capital expenditure is expected to decrease from $49.0 million in FY-2022 to approximately $40.0 million in FY-2023, mainly related to the completion of the Recyn Project which is expected to be commissioned early in H2-2023, as well as the TSF Stage 5 raise and initial design and earthworks on TSF 2. Further, the mineral sizer project is expected to be launched in H2-2023.

¹All Q4-2022 and FY-2022 numbers are preliminary and reflect Endeavour's expected results as at the date of this press release.

Q4-2022 vs Q3-2022 Insights

• Production increased due to higher processed grades and gold recovery rates, partially offset by a decrease in tonnes milled.
  • Total open pit tonnes mined increased as mining activities ramped up at the Maoula open pit.
  • Total underground ore tonnes mined increased as more production stopes were accessed from the Siou underground mine due to the benefit of the underground development conducted in Q3-2022. Across both underground mines, a total of 2,117 meters of development were completed during the quarter.
  • Tonnes milled decreased due to planned mill maintenance, as per the outlook previously disclosed.
  • The average processed grade increased due to higher grade ore feed from the Siou underground.
  • Recovery rates increased slightly due to the change in the ore blend.
• AISC decreased due to higher volumes of gold sold and lower unit processing costs, partially offset by an increase in open pit mining unit costs as a result of the ramp up of mining at the Maoula open pit.

FY-2022 Performance

• FY-2022 production totalled 195koz, exceeding the guided 170-190koz range due to better than expected ore tonnage mined from the Wona open pit before it was depleted and greater volumes of ore sourced from the Siou and Wona underground mines. FY-2022 AISC amounted to approximately $994/oz, slightly below the guided $1,000-$1,100/oz range, largely due to better than expected processed grades throughout the year.
• FY-2022 production decreased from 205koz in FY-2021 to 195koz in FY-2022 largely due to lower grades milled as a result of processing more lower grade stockpiles to supplement the mill feed as open pit mining at the Wona open pit came to a close during the year. FY-2022 AISC decreased from $1,026/oz in FY-2021 to approximately $994/oz in FY-2022 primarily due to an increased proportion of underground mining, and the cessation of open pit mining in the higher cost Wona open pit during the year.

2023 Outlook

• Mana is expected to produce between 190-210koz in FY-2023 at an AISC of $950-1,050/oz.
• In FY-2023, ore will be primarily sourced from the Siou and Wona underground where stope mining is expected to continue throughout the year, supplemented by ore from the Maoula open pit. Processed grades are expected to increase compared to the prior year as higher grade underground ore is expected to represent a larger portion of the mill feed. Production is expected to be weighted to H2-2023 as more stopes are expected to be accessible at the Siou underground mine following the development conducted in H1-2023. The underground development at the Wona underground deposit is expected to continue throughout the year while development of an additional portal is expected to commence in H1-2023.
• Sustaining capital expenditure is expected to increase from $9.9 million in FY-2022 to approximately $25.0 million in FY-2023, with expenditure relating mainly to capitalised underground development and plant maintenance.
• Non-sustaining capital expenditure is expected to decrease from $61.4 million in FY-2022 to approximately $45.0 million in FY-2023, with expenditure relating mainly to Wona underground development, and its associated infrastructure, and the stage 5 lift of the TSF.

¹All Q4-2022 and FY-2022 numbers are preliminary and reflect Endeavour's expected results as at the date of this press release.
²For the post acquisition period commencing 10 February 2021.        .

Q4-2022 vs Q3-2022 Insights

• Production increased due to an increase in processed grade and plant throughput while plant recovery rates remained stable.
  • Total tonnes mined increased with a ramp up of mining activities at the Bambaraya pit and increased ore mining at the Massawa North Zone pits, in addition to the ongoing mining activity at the Sabodala and Massawa Central Zone pits.
  • Tonnes milled increased as the feed blend contained a higher proportion of softer oxide material from the Bambaraya pit while the previous quarter was impacted by the rainy season and downtime associated with scheduled plant maintenance.
  • Average processed grade significantly increased due to the increased contribution of higher grade ore from the Massawa Central Zone and Massawa North Zone pits.
• AISC decreased largely due to higher production driven by the higher grade ore from Massawa and lower processing unit costs driven by lower maintenance costs, while mining unit rates remained consistent.

FY-2022 Performance

• FY-2022 production totalled 358koz, achieving near the bottom end of the guided 360-375koz range due to delays at the end of the year in accessing high grade ore areas and greater volumes of waste extraction in the Massawa North Zone pits than initially scheduled. FY-2022 AISC amounted to approximately $691/oz, within the guided $675-$725/oz range.
• FY-2022 consolidated production increased from 345koz in FY-2021 to 358koz in FY-2022 due to the full year of production following the Teranga acquisition in Q1-2021. FY-2022 AISC increased from $645/oz to approximately $691/oz due to the lower average grade processed and increases in fuel and explosive costs, which were partially offset by foreign exchange benefits and lower sustaining capital.

2023 Outlook

• Sabodala-Massawa is expected to produce between 315-340koz in FY-2023 at an AISC of $760-810/oz.
• In FY-2023 ore will be primarily sourced from the Sabodala and Bambaraya pits with additional higher grade non-refractory ore expected to be sourced from the Massawa Central Zone and Massawa North Zone pits. Tonnes milled and recoveries are expected to be consistent with FY-2022 performance, while grades are expected to be slightly lower as FY-2022 benefitted from higher grade ore from the Sofia Main pit.
• Sustaining capital expenditure is expected to increase from approximately $40.0 million in FY-2022 to $45.0 million in FY-2023, primarily related to capitalised waste as well as fleet re-builds and additional mining equipment purchases.
• Non-sustaining capital expenditure is expected to decrease from approximately $40.1 million in FY-2022 to $35.0 million in FY-2023 and is primarily related to waste capital stripping, infrastructure related to the Massawa mining areas and community resettlement.
• Growth capital expenditure is expected to be $170 million, with further detail on the growth capital spend for the project provided below.

Plant Expansion

• Construction of the Sabodala-Massawa expansion project was launched in April 2022 and remains on budget and on schedule for completion in H1-2024.
• Growth capital expenditure for the expansion project is approximately $290 million, of which $68.1 million was incurred in FY-2022 and approximately $170 million is expected to be incurred in FY-2023 mainly related to process plant and power plant construction activities as well as the TSF-1B construction. Approximately $155 million or 53% of the total growth capital has now been committed, with pricing inline with expectations, mainly related to detailed engineering and design, earthworks, civil works, processing plant construction and long lead items including the mills.
• The construction progress regarding critical path items is detailed below:
  • Bulk earthworks are largely complete with the primary crushing pad and surrounding construction completed.
  • Civil works have continued to progress well with the concrete pour complete for the BIOX reactors and the crusher and reclaim areas. Civil works at the neutralisation area commenced in late November.
  • Processing plant construction is underway, with three BIOX reactors currently being installed.
  • Procurement for the 18MW powerplant expansion is completed and expansion work has commenced.

¹All Q4-2022 and FY-2022 numbers are preliminary and reflect Endeavour's expected results as at the date of this press release.
²For the post acquisition period commencing 10 February 2021.

Q4-2022 vs Q3-2022 Insights

• Production increased due to higher processed grades which was partially offset by slightly lower tonnes milled, while gold recovery rates remained flat.
  • Total tonnes mined increased due to increased mining productivity following the end of the wet season and the benefit of a full quarter of mining at the Samavogo pit. In addition, mining continued at the Nogbele North and South pits while mining at the current stage of the Fourkoura pit ended during the quarter.
  • Tonnes milled decreased slightly due to higher processing plant downtime, which was slightly offset by higher plant utilisation rates.
  • The average processed grade increased due to the addition of higher grade ore sourced from the Samavogo pit.
• AISC decreased compared to the prior period due to increased gold ounces produced and lower sustaining capital incurred associated with less waste stripping during the quarter.

FY-2022 Performance

• FY-2022 production totalled 124koz, which in accordance with the previously disclosed outlook, stands below the guided 140-150koz range mainly due to lower than expected grades from the Nogbele North and South pits during the year. FY-2022 AISC amounted to approximately $1,525/oz, which is above the guided $1,050-$1,150/oz range due to lower volumes of gold sold and higher than expected mining costs driven by a combination of increased unit costs due to the expected higher fuel pricing and greater volumes being mined at a higher strip ratio.
• FY-2022 production decreased from 147koz in FY-2021 to 124koz in FY-2022 due to lower processed grades associated with lower grade ore mined and lower recovery rates, which was partially offset by higher tonnes milled. FY-2022 AISC increased from $994/oz in FY-2021 to $1,525/oz in FY-2022 due to higher than expected mining costs and mining at a higher strip ratio.

2023 Outlook

• Wahgnion is expected to produce between 150-165koz in 2023 at an AISC of $1,250-1,350/oz.
• Ore is expected to be primarily sourced from the Nogbele North and Samavogo pits, with mining at the Nogbele South pits scheduled to end in H1-2023 and commencement of mining at the Stinger pits expected in H2-2023. Production is expected to be weighted to the second half of the year as greater volumes of ore are expected to be sourced from the Samavogo pit in H2-2023, as the strip ratio reduces and increased volumes of relatively higher grade ore become available. Mill throughput rates are expected to be similar to FY-2022 while grades are expected to increase with the full year benefit of higher grade deposits.
• Sustaining capital expenditure is expected to increase slightly from $23.2 million in FY-2022 to approximately $25.0 million in FY-2023, and primarily relates to waste stripping at the Samavogo, Stinger and Nogbele North pits.
• Non-sustaining capital expenditure is expected to decrease from $31.6 million in FY-2022 to approximately $15.0 million in FY-2023, and primarily relates to mining infrastructure at the Stinger pit including haul road construction, a TSF raise and resettlement activities.

 

Lafigué Project Construction

• Construction of the Lafigué project on the Fetekro property in Côte d'Ivoire was launched in early Q4-2022, following the completion of a DFS which confirmed Lafigué’s potential to be a cornerstone asset for Endeavour. The project will have a 4Mtpa capacity CIL plant, with an annual average production of 203koz at a low AISC of $871/oz over its initial 12.8 year mine life, with significant exploration potential on the Fetekro property. First gold production is scheduled for Q3-2024.
• Growth capital expenditure for the project is approximately $448 million, of which $47.5 million was incurred in FY-2022 and approximately $230 million is expected to be incurred in FY-2023 mainly related to further earthworks and civil works as well as process plant and TSF construction activities. Approximately $136 million or 30% of the total growth capital has now been committed, with pricing inline with expectations, mainly related to site roads, the construction camp and offices, airstrip construction, perimeter fencing, process plant earthworks and the detailed engineering.
• The construction progress regarding critical path items is detailed below:
  • Process plant earthworks and civil works are well underway with key earthworks for the crushing area now completed and further earthworks for supporting infrastructure underway. Foundations for the CIL tank ring beams have been poured and mill foundations will be poured in Q1-2023.
  • Long lead packages have now all been awarded including the ball mill, HPGR, thickeners, apron feeders, jaw crushers and cone crushers, with contracted dates in line with the construction schedule.
  • Earthworks for the TSF are nearing completion.
  • Construction of the 225kv power line is ongoing with transmission tower manufacturing expected to be completed in H1-2023.

These measures are presented as they can provide useful information to assist investors with their evaluation of the pro forma performance. Since the non-IFRS performance measures listed herein do not have any standardised definition prescribed by IFRS, they may not be comparable to similar measures presented by other companies. Accordingly, they are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. Please refer to the non-GAAP measures section in this press release and in the Company’s most recently filed Management Report for a reconciliation of the non-IFRS financial measures used in this press release.
