Liberty Gold Announces Maiden Resource Estimates for Five Gold and Copper Deposits at the TV Tower Project, Turkey
Liberty Gold has announced significant independent mineral resource estimates from its TV Tower Property in Turkey, enhancing the existing resource base by over threefold. The 92 km² site, 62.9% owned by Liberty Gold, now includes two gold oxide deposits and three gold-copper porphyry deposits. The detailed estimates reveal substantial amounts of gold, silver, and copper, with multiple undrilled targets remaining. The company aims to elevate the profile of TV Tower while focusing on pre-development efforts primarily at its Black Pine and Goldstrike sites.
- Resource estimates increased by over 300% at TV Tower Property.
- Multiple undrilled gold, copper, and silver targets indicate potential for further resource expansion.
- The project is accessible year-round and close to critical infrastructure.
- Focus remains on Black Pine and Goldstrike, which may divert resources from TV Tower.
- Current resource estimates are classified as Indicated and Inferred, indicating uncertainty in economic viability.
New Resources Triple Gold and Copper Endowment at TV Tower; Multiple Undrilled Targets Remaining to be Tested
VANCOUVER, British Columbia, April 06, 2021 (GLOBE NEWSWIRE) -- Liberty Gold Corp. (TSX:LGD; OTCQX:LGDTF) ("Liberty Gold" or the "Company") is pleased to announce maiden independent Mineral Resource Estimates at its 92 square kilometer (“km2”),
The TV Tower Property is located in the Biga Peninsula, home to numerous epithermal gold and silver and gold-copper porphyry deposits, mines and development projects. The project is road accessible year-round and close to power generation facilities and deep-water ports.
Table 1 is a summary of the mineral resource endowment for the TV Tower Property, with an additional breakdown of resource subsets in subsequent tables.
The TV Tower Property is divided into South (“South TVT”) and North (“North TVT”) resource areas. The South TVT resource area contains four geographically separate deposits (Kayalı and Yumrudağ oxide gold deposits and Hilltop and Valley Au-Cu porphyry deposits), all located within a 4 km2 area.
The North TVT resource area, located approximately 7 km north of the South TVT resource area, hosts two deposits: the Columbaz Au-Cu porphyry and the Küçükdağ high sulphidation epithermal (“HSE”) Au-Ag-Cu deposit (“North TVT KCD”). The former is comprised of two resource zones based on mineralogy and anticipated milling technique: North TVT Au-Cu Porphyry and North TVT Oxidized Porphyry. KCD was the subject of a 2014 resource estimate that is still current.
All deposits are open for extension laterally and to depth.

“While we are primarily focusing our pre-development efforts on oxide gold at Black Pine and Goldstrike in the Great Basin, it was deemed appropriate to raise the profile of the TV Tower Property now. Multiple gold, copper and silver deposits occur within this large land package,” commented Cal Everett, President and CEO of Liberty Gold. “The six deposits discovered to date remain open for extension laterally and to depth. When the discoveries were made, drilling stayed focused until another deposit was identified and drill tested. TV Tower is still in the early stages of exploration and discovery. We are now assessing our options to crystallize value for our shareholders.”
Moira Smith, V.P. Exploration and Geoscience for Liberty Gold, commented, “When we resumed operatorship of the TV Tower Property in 2012, it was with a vision that the property’s massive alteration zones contained multiple centres of epithermal gold and silver mineralization and porphyry Au-Cu mineralization that could give rise to multiple millions of gold-equivalent ounces. Today, we can provide proof of concept, and with multiple untested targets, we are confident that the resource endowment at TV Tower will continue to grow.”
MINERAL RESOURCE ESTIMATES FOR TV TOWER DEPOSITS
TV Tower is underlain by intermediate volcanic rocks and intrusive bodies. The highest elevations of the property are host to residual quartz ledges and ribs with oxidized HSE gold mineralization and/or unoxidized gold-silver-copper mineralization. Gold-copper porphyry systems lie immediately under or adjacent to the oxidized gold zones, often with a zone of supergene copper mineralization at the interface.
The four South TV Tower deposits contain multiple ore types and corresponding resource subsets by ore type and cut-off grade, with the breakdown illustrated in Table 2. These resource subsets comprise the South TVT Oxide Gold; South TVT Supergene Copper; and South TVT Au-Cu Porphyry subsets. The four deposits all lie within a 4 km-long trend, such that separate milling and heap leaching operations, managed as a single operation, would reasonably be expected to accommodate mineralized material from all of the deposits.
The two North TV Tower deposits contain three ore types and corresponding resource subsets (North TVT Au-Cu Porphyry, North TVT Oxidized Porphyry and North TVT KCD HSE Au-Ag-Cu resource subsets). The two deposits are located within 1.5 km of each other such that it is reasonable to expect that they would be developed using common infrastructure. However, without further analysis, it is uncertain at this time whether the North TV Tower and South TV Tower deposits would be developed using common infrastructure.

SOUTH TV TOWER OXIDE GOLD RESOURCE
The Kayalı and Yumrudağ gold oxide deposits are located at either end of a 4 km-long ridge in the southern portion of the TV Tower Property. Both deposits are open in several directions, and the Yumrudağ deposit in particular has seen relatively little drilling to date. The deposits comprise elemental gold with iron oxides in a matrix of vuggy quartz replacing intermediate volcanic rocks and are interpreted to represent oxidized high sulphidation epithermal gold systems.
In the central, lower-elevation portion of the ridge, the upper portion of the Hilltop gold-copper porphyry deposit is exposed and oxidized, leaving a shallow blanket of oxidized gold-only mineralization. This mineralization was also included in the estimate.

KEY POINTS
- The Kayalı and Yumrudağ gold oxide deposits and Hilltop Porphyry shallow gold oxide zones are located along a 4 km long ridge and contain oxide gold on surface and at shallow depth.
- Column testing by Liberty Gold suggests that Kayalı and Yumrudağ are amendable to heap leaching, with 70 –
90% extraction achieved in four column tests using 0.5 inch crush size. Additional details of the column testing program are provided below, with a full description to be provided in the TV Tower Technical Report. - Kayalı is open for expansion to the northwest and southeast. Yumrudağ is open in all directions.
SOUTH TV TOWER SUPERGENE COPPER RESOURCE
The Kayalı deposit oxide gold zone is underlain by a relatively flat-lying blanket of disseminated chalcocite. The potential significance of the copper zone was recognized late in the drilling process, is relatively untested, and potentially open in several directions.
Copper was likely originally part of the unoxidized gold deposit, but was leached and redeposited as chalcocite at the base of the oxidized gold zone. Chalcocite in similar settings is amenable to recovery by conventional flotation.

1See notes below Table 3 and in the Resource Estimation section of this press release for estimation parameters and other information about estimation procedures.
KEY POINTS
- Supergene copper as a potentially economic mineralization type has not been fully explored at TV Tower, with a density of drilling sufficient to estimate a resource only realized at Kayalı.
- The primary copper mineral is chalcocite, which is readily amenable to recovery by flotation and concentration.
- Supergene chalcocite is recognized beneath the oxide zone at Hilltop Porphyry, the lower portion of the Yumrudağ deposit and other areas where oxidized HSE mineralization is present.
SOUTH TV TOWER AU-CU PORPHYRY DEPOSITS: HILLTOP, VALLEY AND YUMRUDAĞ
Hilltop and Valley are Au-Cu porphyry deposits, characterized by the presence of free gold and copper in chalcopyrite and lesser bornite and chalcocite. Preliminary concentrate testing by Liberty Gold and a previous operator suggest the amenability of both deposits to recovery of copper and gold to a concentrate (see below for more information regarding the metallurgical program).
The Valley porphyry deposit represents the deeper portion of a porphyry system, characterized by the presence of strong quartz stockwork veining, potassium feldspar and magnetite alteration hosted in quartz monzonite. The Hilltop porphyry represents the higher levels of a porphyry system, characterized by free gold and copper in chalcopyrite and chalcocite in sericite and biotite altered quartz monzonite porphyry. The Hilltop deposit remains open in several directions.
Gold-copper mineralization located immediately beneath the Yumrudağ gold oxide zone includes areas of chalcocite mineralization likely representing a supergene copper blanket, superimposed on a weakly-developed Au-Cu porphyry system. The difference in style of mineralization would account for the relatively high ratio of copper to gold in this deposit relative to Hilltop and Valley. It is relatively sparsely drilled, with more drilling necessary to fully define the system, which is open in all directions.

1See notes below Table 3 and in the Resource Estimation section of this press release for estimation parameters and other information about estimation procedures.
KEY POINTS
- The Hilltop Au-Cu porphyry deposit lies 3 km to the northeast of the Valley Au-Cu porphyry deposit, and immediately east of the Yumrudağ Cu-Au zone. All three zones of mineralization would logically be processed at a central mill facility.
- The Hilltop and Yumrudağ mineralized zones are open to expansion in several directions.
- Preliminary metallurgical testing by Liberty Gold suggests that the Valley porphyry deposit would be amenable to producing a high-grade concentrate using a flow-sheet similar to the nearby Halilağa Au-Cu porphyry deposit, with concentrate grades after 2 cleaner stages ranging from
32.0% Cu to44.2% Cu and from 44.7 g/t Au to 84.5 g/t Au. - Preliminary metallurgical testing at the Hilltop porphyry deposit by a previous operator produced acceptable results using rougher flotation, but cleaner recoveries were poor due to no regrind, so more testing is needed to optimize results. See below for more information regarding the metallurgical programs at TV Tower.
- No metallurgical testing has been carried out at Yumrudağ, but the presence of free gold and copper in chalcocite and chalcopyrite suggest conventional Cu flotation should perform well.
- The South TV Tower Au-Cu porphyry deposits are located approximately 15 km west of the Halilağa Au-Cu porphyry deposit, currently in development.
NORTH TV TOWER DEPOSITS
The northeast portion of the TV Tower Property hosts two deposits: The Columbaz deposit comprising a Au-Cu porphyry system cut by low sulphidation Au-Ag quartz veins and the KCD high sulphidation Au-Ag-Cu deposit, lying 1.5 km to the north of Columbaz.
Columbaz Au-Cu Porphyry Deposit
The Columbaz Au-Cu porphyry system was discovered in 2014 when core drilling targeting LSE Au-Ag quartz veins intersected the top of a porphyry system at shallow depth (see press releases dated 22 October, 2014 and 06 February, 2015). A total of 5 holes intersected the porphyry system. A deep induced polarization (“IP”) survey over the area showed that a large chargeability high covered upwards of 0.6 km2, within a 2 km2 area with multiple chargeability highs, an area much larger than had been drill tested. Five additional holes were drilled to the north and south of the original drill holes in late 2020, showing that mineralization continued to the north and south, and to a depth of at least 740 m (Table 6).
The Columbaz porphyry Au-Cu system consists of copper as chalcopyrite and free gold in phyllic, potassic and magnetite altered volcanic rocks, phreatic breccias and polyphase quartz monzonite porphyry of Eocene age. Mineralization extends from surface to over 740 m, and includes a small amount of oxidized, gold-only material. Portions of the system are cut by gold- and silver-bearing, LSE quartz veins. The Columbaz porphyry system has a strong magnetic and IP chargeability signature. The roughly coincident magnetic and IP chargeability anomaly covers several square km extending to the north of the Columbaz resource area, and only a small portion of it has been drill tested to date.
The Columbaz porphyry resource estimate is shown below in Table 7.
For a map of the Columbaz area, IP anomaly and drill collars, please click here:https://libertygold.ca/images/news/2021/April/TVTower_NR040621ColumbazMap.pdf
KEY POINTS
- The Columbaz porphyry system has been intersected by a total of only 11 drill holes, with Au-Cu mineralization extending to a depth of at least 740 m.
- The drill density is sufficient to estimate inferred resources, but the deposit requires more infill and step-out drilling to test the extents of mineralization and estimate indicated resources.
- Drilling to date has tested only a small portion of a much larger IP and magnetic anomaly that extends northward from the Columbaz deposit over an area of approximately 2 km2.
- No metallurgical testing has been carried out at Columbaz. However, the mineralogy is very similar to the Hilltop deposit, for which metallurgical testing indicates that it is amenable to recovery of copper and gold by flotation.
- Permitting is underway to gain access to and test the large, undrilled IP anomaly.

KCD HSE Au-Ag-Cu Deposit
The KCD deposit is a high-sulphidation system characterized by a zone of gold and copper mineralization overlain by a zone of predominantly silver mineralization. KCD was the subject of an intensive drill program in 2012 and 2013, with a maiden resource estimate in 2014. Mineralogically, the gold zone contains largely enargite, silver sulphosalts and gold in association with arsenian pyrite and enargite, while the overlying silver zone contains abundant pyrite with very fine-grained silver minerals. It also contains an average of 18 ppm tellurium in the gold zone.
The resource estimate is still current and will be included in the TV Tower Technical Report. For full details, please see the full 2014 Technical Report available on Liberty Gold’s website or under Liberty Gold’s profile on www.sedar.com.

1The Classified Mineral Resource estimate is quoted at a cut-off grade of 0.50 g/t AuEq. At a 0.50 g/t AuEq cut-off, the strip ratio is 1.47:1. Gold equivalence was calculated using a ratio of Au:Ag of $1200:$20, at
UNDRILLED TARGETS
In addition to the six drilled deposits with resource estimates and possible extensions to these deposits, several other undrilled targets remain on the property. These include:
- Gümüşlük, a gold-copper-silver target hosted in metamorphic rocks suspected to be a listwaenite lode-gold system. The target is a strong copper-gold-silver soil anomaly measuring over 1 km long by 400 m wide, with individual soil samples returning assays up to 6 g/t Au and 92 g/t Ag and rock samples up to 9 g/t Au.
- Tesbihçukuru, an Au-Cu porphyry target located approximately 4 km north of the Hilltop porphyry deposit and 4 km south-southwest of the Columbaz porphyry deposit, characterized by:
- Outcropping, oxidized porphyry-style quartz-stockwork alteration.
- Au up to 0.6 g/t and Cu up to
0.27% in channel samples. - A large IP chargeability anomaly.
- Kestanecik, 1 km x 1 km zone of strong argillic alteration with LSE quartz veins containing gold and silver.
- Kartaldağ West, a 1 km-long, oxidized HSE gold target located 1.5 km northeast of Gümüşlük.
RESOURCE ESTIMATION (OTHER THAN KCD)
The resource estimate was completed by Mr. Mehmet Ali Akbaba, P. Geo., AIPG, an Independent Qualified Person as defined by NI 43-101, in accordance with the CIM Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended. Estimation methods are summarized below. Further details of the estimation methods and procedures will be available in the TV Tower Technical Report, authored by DAMA Mühendislik A.Ş., that will be filed within 45 days of the date of this press release, and which will be available on SEDAR (www.sedar.com) and on Liberty Gold’s website.
The resource estimate is based on results from 30,055.2 metres of drilling in 122 drill holes (113 core and nine reverse circulation) for the deposits (i.e., Hilltop, Yumrudağ, Valley and Kayalı) in the TV Tower South area and 8,353.1 meters of drilling in 11 drill holes for the Columbaz prospect in the TV Tower North area.
Quality-control data generated for the various drill programs were independently verified by DAMA as part of the project review. The resource model consists of a detailed three-dimensional geological model including lithological and grade domains. These, in turn, were used to constrain the interpolation of gold and copper grades. Block grades were estimated by ordinary kriging.
Blocks sizes are 10 x 10 x 5 meters for the South TV Tower deposits and 20 x 20 x10 meters the North TV Tower (Columbaz) deposit. In the South TV Tower database, a total of 9,981 individual assay intervals averaging 1.47 m in length were composited into a total of 7,753 composite intervals of 2.00 m length, while a total of 2,771 individual assay intervals with an average length of 1.42 m in the Columbaz deposit at the North TV Tower sector were composited into a total of 1,978 composite intervals of 2.00 m length.
Gold and copper assay data were reviewed statistically to determine appropriate grade capping levels by domain. A total of 95 gold assays and 51 copper assays in the South TV Tower database and a total of 14 gold assays in the North TV Tower database were capped prior to compositing.
All North TV Tower mineralization (i.e., Columbaz) within the pit shell was classified as Inferred. For the South TV Tower deposits, Mineral Resources estimated with a minimum of two holes and 4 composites within 50 m were classified as Indicated, while all other above cut-off material within the pit shell was classified as Inferred.
The mineral resources are confined within a Micromine pit shell generated by DAMA to ensure reasonable prospects of economic extraction. The pit shell was based on the following parameters: Au:
METALLURGICAL TESTING
Metallurgical testing was carried out on oxide and hypogene sulphide material from the Kayalı, Yumrudağ, Hilltop, Valley and KCD deposits. KCD metallurgical testing is described in the 2014 Technical Report.
In 2015, three master composites from oxide material in five drill holes at Kayalı (Kayalı-1, Kayalı-2 and Kayalı-3) and one composite from one hole at Yumrudağ (Yum-1) were prepared from drill core and shipped to McClelland Laboratory in Reno, Nevada, USA for a preliminary heap leach amenability study, under the supervision of G.L. Simmons Consulting LLC. Scope of work included:
1. Composite preparation and feed analysis
2. Detailed comminution test work (Kayalı-1 and Yum-1 only)
3. Bottle roll tests (BT) on P801.7mm (168 hour leach) and P8075μm feed sizes
4. Head screen analysis
5. Column percolation leach tests (CT) on P8012.5mm feeds
6. Tail screen analyses on CT leached/rinsed residues
Results show that composites are amenable to cyanidation processing. Highest gold extractions were achieved from P8075μm feeds showing that milling will liberate Au for dissolution by cyanide. Overall, results show that composites Kayalı-1, Kayalı-2 and Kayalı-3 and Yum-1 are potentially amenable to heap leach processing at the P8012.5mm crush size. Respective gold extractions were 84.2, 71.1, 73.6 and 90.6 percent in 80 to 120 days of leaching and rinsing.
In 2014, five master composites (VPMC-1 to VPMC-5) were generated from drill core from the Valley Porphyry deposit and subjected to laboratory flotation testing conducted by John Gathje Consulting, LLC, an independent consultant, using the facilities and support provided by Hazen Research, Inc. (Golden, Colorado). Samples were subject to a primary grind P80 of 140μm followed by rougher flotation using lime to adjust to ±pH 9 and potassium amyl xanthate (PAX) as the collector. The rougher concentrate was reground to a P80 of 20μm and two or three stages of cleaning were used to produce a final copper concentrate product. The pH during cleaning is maintained at ~11 to 11.5 (using lime) to reject pyrite.
For VPMC-1 to VPMC-4 two cleaner stages produced copper concentrates with grades >
At the Hilltop deposit in 2012, previous owner Chesser Resources Limited commissioned Ausenco and ALS Metallurgy of Balcatta, WA, Australia to carry out preliminary rougher and cleaner floatation testing, which was carried out on three samples from drill hole KAD-02. The samples had a range of Cu grades from 0.3 to
Full details of the metallurgical testing programs at TV Tower will be disclosed in the TV Tower Technical Report.

Cautionary Note for United States Investors
The terms “mineral resource”, “measured mineral resource”, “indicated mineral resource” and “inferred mineral resource”, are Canadian mining terms as defined in, and required to be disclosed in accordance with, National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”), which references the guidelines set out in the Canadian Institute of Mining, Metallurgy and Petroleum (the “CIM”) – CIM Definition Standards on Mineral Resources and Mineral Reserves (“CIM Definition Standards”), adopted by the CIM Council, as amended. However, these terms are not defined terms under SEC Industry Guide 7 (“SEC Industry Guide 7”) under the United States Securities Act of 1933, as amended, and normally are not permitted to be used in reports and registration statements filed with United States Securities and Exchange Commission (the “SEC”). The SEC has adopted amendments to its disclosure rules to modernize the mineral property disclosure requirements for issuers whose securities are registered with the SEC under the United States Securities Exchange Act of 1934, as amended. These amendments became effective February 25, 2019 (the “SEC Modernization Rules”) with compliance required for the first fiscal year beginning on or after January 1, 2021. The SEC Modernization Rules replace the historical disclosure requirements for mining registrants that were included in SEC Industry Guide 7. The Company does not file reports with the SEC and is not required to provide disclosure on its mineral properties under the SEC Modernization Rules and will continue to provide disclosure under NI 43-101 and the CIM Definition Standards.
United States investors are cautioned that there are differences in the definitions under the SEC Modernization Rules and the CIM Definition Standards. There is no assurance any mineral resources that the Company may report as “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources” under NI 43- 101 would be the same had the Company prepared the resource estimates under the standards adopted under the SEC Modernization Rules. United States investors are also cautioned that while the SEC will now recognize “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources”, investors should not assume that any part or all of the mineralization in these categories will ever be converted into a higher category of mineral resources or into mineral reserves. Mineralization described using these terms has a greater amount of uncertainty as to their existence and feasibility than mineralization that has been characterized as reserves. Accordingly, investors are cautioned not to assume that any “measured mineral resources”, “indicated mineral resources” or “inferred mineral resources” that the Company reports are or will be economically or legally mineable. Further, “inferred mineral resources” have a greater amount of uncertainty as to their existence and as to whether they can be mined legally or economically. Therefore, United States investors are also cautioned not to assume that all or any part of the “inferred mineral resources” exist. In accordance with Canadian securities laws, estimates of “inferred mineral resources” cannot form the basis of feasibility or other economic studies, except in limited circumstances where permitted under NI 43-101. In addition, the SEC has amended its definitions of “proven mineral reserves” and “probable mineral reserves” to be “substantially similar” to the corresponding CIM definitions. United States investors are cautioned that a preliminary economic assessment cannot support an estimate of either “proven mineral reserves” or “probable mineral reserves” and that no feasibility studies have been completed on the Company’s mineral properties.
Accordingly, information contained herein describing the Company’s mineral deposits may not be comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements under the United States federal securities laws and the rules and regulations thereunder.
