TORONTO, Nov. 02, 2022 (GLOBE NEWSWIRE) -- Hudbay Minerals Inc. (“Hudbay” or the “company”) (TSX, NYSE: HBM) today announced an update on various exploration initiatives, including an initial mineral resource estimate for the Llaguen copper deposit located in the Otuzco province in the La Libertad region in Peru.
“We have a rich pipeline of organic copper growth projects at Hudbay and our Llaguen property adds another exciting opportunity to this pipeline,” said Peter Kukielski, President and Chief Executive Officer. “Our pipeline also includes the Maria Reyna and Caballito properties near Constancia where our exploration team has confirmed copper mineralization that could add meaningful long-term value for our Peru operations. We also continue to have exploration success at our Copper World project in Arizona and we look forward to an initial drill program to test the down-dip extensions of Lalor at depth in 2023. The opportunities arising from our pipeline of organic copper growth projects comes at an opportune time with the global scarcity of new copper assets and long-term global copper supply unable to meet the demands from a low carbon future. We have an extremely talented exploration team at Hudbay and we are excited to continue to add value to these projects through the drill bit.”
“The initial mineral resource estimate for our Llaguen project has confirmed the presence of a significant copper-molybdenum porphyry deposit at a higher level of geological confidence than we expected at this stage due to the continuous nature of the mineralization,” said Andre Lauzon, Senior Vice President and Chief Operating Officer. “The mineral resources include a significant higher-grade component located near surface, with a low 0.9 strip ratio and the potential to be mined in the initial years of production to maximize the economics for the project. This project benefits from its location at moderate altitude, close to regional infrastructure and the city of Trujillo.”
Llaguen Initial Mineral Resource Estimate
The Llaguen project is
Hudbay optioned the property from a Vale subsidiary in 2017 and has since completed an exploration agreement with the local community, conducted additional geological mapping and geochemical sampling, and completed a 28-hole confirmatory drill program during 2021 and 2022. Hudbay’s tenement comprises 12 mining concessions totaling 8,900 hectares and the mineralization is fully contained within these
Successful Confirmatory Drill Program
In the summer of 2021, Hudbay began a confirmatory drilling campaign over a known copper and molybdenum rich mineralized zone. The mineralized zone was previously identified from a 23-hole historical drill program completed by Vale from 2006 to 2008, which was based on a chargeability anomaly identified from a ground geophysical survey. The porphyry mineralization is hosted in tonalite rocks with late-stage hydrothermal breccia with tourmaline and semi-massive molybdenite veins along fractures. Hudbay’s exploration program at Llaguen included an initial campaign of 28 diamond drill holes duplicating and infilling the widely spaced holes historically drilled by Vale.
Hudbay’s drilling confirmed and extended the footprint of the known mineralization and highlighted the existence of a high-grade tourmaline rich brecciated zone in the center of the deposit, which starts from surface and is almost entirely contained within the pit shell hosting the initial mineral resource (please refer to Figure 2). The deposit is now defined by a total of 51 drillholes all with mineralized intercepts. As illustrated in Figure 3, the Llaguen mineralization in most cases starts from surface with a low strip ratio of 0.9 and contains higher-grade mineralization at the center of the deposit.
High-grade Mineral Resource Underlying the Global Mineral Resource Estimate
Based on the assay results compiled and validated as of August 31, 2022, the initial mineral resource estimate for the Llaguen deposit contained within an economic pit shell is summarized in Table 1 below.

Llaguen Remains Open and Several Regional Exploration Targets Untested
The Llaguen mineralization defined by Hudbay’s recent drilling campaign remains open at depth and to the northeast and northwest in a new porphyry with disseminated mineralization. In addition, mapping has confirmed the continuity of the mineralized system to the southeast, coincident with geochemistry and chargeability anomalies along a structural corridor with several additional targets that have been identified and could be tested in the future to further grow the mineral resource estimates (please refer to Figure 4). The current mineral resource is also surrounded by a large halo of low grade hypogene copper mineralization, not currently included in the mineral resource estimate, for which metallurgical test work could assess the potential for sulfide heap leaching via commercially available technologies.
Llaguen Next Steps
Hudbay has initiated preliminary technical studies at Llaguen, including metallurgical test work as well as geotechnical and hydrogeological studies, which are expected to be incorporated into a preliminary economic assessment for the Llaguen project. Additional exploration drilling is warranted on the property to test the areas of the deposit that remain open and the several untested geophysical targets in the area to fully define the regional extent of the mineralization.
Early Exploration Activities Commence at Maria Reyna and Caballito
Hudbay controls a large, contiguous block of mineral rights with the potential to host mineral deposits within trucking distance of the Constancia processing facility, including the past producing Caballito property and the highly prospective Maria Reyna property. Geophysical surveys indicate large-scale potential at Maria Reyna and Caballito, as shown in Figure 5.
In August 2022, the company executed a surface rights exploration agreement with the community of Uchucarcco that allows for exploration of the Maria Reyna and Caballito properties. Shortly after the agreement was completed, Hudbay commenced baseline environmental and archaeological activities to advance the permitting process to allow for drilling the property in the future. The company’s geological team also commenced surface investigation activities and field evidence confirms that both Caballito and Maria Reyna host sulfide and oxide rich copper mineralization in skarns, hydrothermal breccias and large porphyry intrusive bodies.
Caballito
The past producing Caballito property is located approximately five kilometres from Constancia and includes an open pit mine (formerly called Katanga) that was operated by Mitsui Mining and Smelting Co. (“Mitsui”) until the early 1990s. Hudbay collected hand samples in the old Mitsui pit which confirmed the mineralization is both copper oxides and sulfides rich with extensive occurrence of chalcopyrite and bornite and copper oxides in various forms. Please refer to Figure 6 for images of Hudbay’s hand samples and the waste rock pile near the old Mitsui open pit. Part of Hudbay’s immediate exploration plans consist of surveys and the collection of samples from the historical waste stockpiles to assess their size and composition.
A U.S. Geological Survey from 1990 estimated a historical mineral resource estimate of 90.9 million tonnes at
Maria Reyna
The Maria Reyna property is located approximately 10 kilometres from Constancia and hosts three types of mineralization – skarn, hydrothermal breccia and porphyry – with magnetite and garnet skarns and hydrothermal breccias having the potential to host high grade zones, as shown in Figure 7. Artisanal mining activity is present in these high-grade areas in the form of small-scale selective mining operations reported by the local operators to produce at an average grade ranging between
Historical drilling in the Maria Reyna south-west zone completed by a previous owner consisted of 11 diamond drill holes covering a total of 5,585 meters. The historical drill results include 136 metres at
Manitoba Exploration Continues to Grow Resources and Find Extensions
Hudbay’s 2022 exploration efforts in Manitoba have been focused on completing ongoing infill drilling at Lalor and 1901 and confirmatory drilling at the Flin Flon Tailings Impoundment System as part of the early technical evaluation of the opportunity to reprocess tailings. Hudbay continues to have resource conversion success at Lalor, which will be incorporated into the company’s annual mineral resource and reserve estimate update in the first quarter of 2023. Hudbay is also in the process of planning a winter drill program to test the down-dip gold and copper-gold extensions of the Lalor deposit in 2023, which will be the first time the company has completed step-out drilling in the deeper zones at Lalor since 2009.
Flin Flon Tailings Drilling Indicates Higher Grade than Expected
In 2021, Hudbay identified the opportunity to reprocess Flin Flon tailings where in excess of 100 million tonnes of tailings have been deposited for over 90 years. The company recently completed confirmatory drilling which covered about two-thirds of the facility, as shown in Figure 8. The results indicate higher zinc, copper and silver grades than predicted from historical mill records while confirming the historical gold grade. For more information, please see the table of drill hole intersections provided at the end of this news release. Hudbay plans to complete metallurgical test work on the Flin Flon tailings to assess the processing viability.
Hudbay also intends to evaluate the opportunity to reprocess the tailings at the Anderson facility in Snow Lake given significant amounts of gold have been deposited over many decades. The gold processing capacity in Snow Lake is enhanced with the recent start-up of the New Britannia mill and Hudbay’s initiatives underway to improve the gold recoveries at the Stall mill.
Continued Exploration Success at Copper World Increases the Size of Bolsa
Hudbay continues to have three drill rigs turning at Copper World and recent drilling completed since the preliminary economic assessment was published in June 2022 has increased the extent of the mineralization at the Bolsa deposit. Drilling has confirmed the continuity of the mineralization between the Bolsa and East deposits and extended the width and depth of the mineralized envelope, as shown in Figure 9. The gain in volume has the potential to more than double the volume of the Bolsa deposit, and while most of the increased mineralization is located on patented mining claims, it is likely to only benefit the mine plan during the second phase of the Copper World project given the first phase already maximizes the use of available private land for mining and waste disposal. The combined mineralized zone remains open in several directions and at depth.
Nevada Regional Exploration Update
A conductivity-resistivity IP ground survey commenced in October 2022 at the Mason Valley properties located on Hudbay’s private land claims near the Mason project. This work, in combination with a re-interpretation of geological data from past operating mines and previous exploration data, will be used to finalize a drill plan to test high grade skarn targets in 2023. The objective is to repeat the success of the Copper World discoveries in a very similar geological setting with the same history of small-scale operations extracting high-grade copper via small open pit and underground mines in the early part of the 20th century.
Qualified Person and NI 43-101
The scientific and technical information contained in or incorporated by reference into this news release has been prepared under the supervision of Olivier Tavchandjian, P. Geo., Hudbay’s Vice President, Exploration and Technical Services. Mr. Tavchandjian is a “qualified person” for purposes of NI 43-101.
At Llaguen, a total of 51 holes drilled by Hudbay and previous owners of the project area have intersected copper-molybdenum mineralization and were used to define the Llaguen deposit. The Llaguen mineral resource estimates were estimated assuming a selective mining unit of 20 metres x 20 metres x 15 metres and within an economic pit shell defined by a Lerch Grossman algorithm. Hudbay is not aware of any drilling, sampling, recovery, or other factors that could materially affect the accuracy or reliability of the Llaguen mineral resource estimate disclosed in this news release.
The methodology followed to estimate mineral resources at Llaguen is identical to the approach used for several years at Hudbay’s Constancia mine in Peru where the mineral resource and reserve estimates have shown good reconciliation results with mill credited production (please refer to the NI 43-101 Technical Report for Constancia dated March 29, 2021 for more details, which is available on the company’s SEDAR profile at www.sedar.com).
Mr. Tavchandjian has verified the Llaguen exploration data disclosed in this news release, including sampling, analytical, and test data underlying the information or opinions expressed herein. The data verification and quality assurance / quality control (“QA/QC”) measures that were used as part of the Llaguen drill program conducted by Hudbay since June 2021 are summarized below:
- Recent exploration core drilling done by Hudbay at the Llaguen porphyry deposit was a combination of HQ and NQ size. Drill core was removed from the core tube by drilling contractors and placed in labelled core boxes. Core was logged by geologist, photographed, tagged with sample tags including drillhole number and depth. Core was cut in half and placed in labeled sample bags with the sample tags weighed in a digital balance and transported via commercial truck from the core storage facilities in Trujillo to the analytical Laboratories in Lima for preparation and analysis. For duplicate samples, the drill core samples were cut for a second time, resulting in a ¼ drill core sample. Two selected independent commercial analytical laboratories were used: Bureau Veritas Lima (“BV”) and SGS Lima (“SGS”). The remaining second half and ¼ of the core was securely stored at the Trujillo storage facility for eventual verification purposes and further analysis if required.
- Drill core samples were prepared and assayed following industry standard analytical protocols at each laboratory. Analyses were carried using multi acid digestion to achieve near total dissolution with an ICP-AES finish (Methods MA301 at BV and ICP40B at SGS). Gold was analyzed by fire assay with AAS finish (Methods FA430 at BV and FAA313 at SGS). Samples with concentration of Cu>10,000 ppm and Mo>10,000 ppm were reanalyzed by resource grade multi acid digestion with ICP-AES finish (Methods MA402 at BV and AAS41B at SGS). Three stages Cu Sequential Analysis (sulfuric acid leach followed by sodium cyanide leach followed by CuRes CLL) were analyzed by methods LH-SEQ at BV and AAS73B at SGS. QA/QC included the insertion of
3% of samples as blank material,3% as standards (from 2 certified OREAS reference materials) and3% as ¼ drill core duplicates. Failure rates were nominal in all cases and no significant QA/QC issue was identified. - The validity of using historical Vale drilling, for which QA/QC results are not available, was confirmed by conducting a global comparison of grade interpolation using this data versus the recent drilling done by Hudbay.
Because of its early stage of development, Hudbay does not consider the Llaguen deposit to be a material mineral property for purposes of NI 43-101.
Certain information in this news release regarding potential mineralization at Caballito and Maria Reyna is based on information that has been obtained from publicly available information and/or industry reports, which constitute “historical estimates” for the purposes of NI 43-101. Such reports generally state that the information contained therein has been obtained from sources believed to be reliable, but the accuracy or completeness of such information is not guaranteed. While the company considers such historical estimates to be relevant for purposes of this news release as they may indicate the presence of mineralization, the qualified person for the company has not done sufficient work to classify the historical estimates as current "mineral resources" or "mineral reserves" (as defined in NI 43-101). The historical estimates contained in this news release are not compliant with NI 43-101 and the company is not treating the historical estimates as current "mineral resources" or "mineral reserves". A thorough review of all historical data performed by a qualified person, along with additional exploration work to confirm results, would be required to produce a current mineral resource estimate prepared in accordance with NI 43-101. The company has not independently verified and cannot guarantee the accuracy or completeness of the historical estimates and other third-party data contained in this news release and investors should use caution in placing reliance on such information.

Notes:
1 Drilling was completed with a LS250 Sonic drill with samples vibrated out of the core barrel into a long plastic bag and then cut in half, with one half going into a plastic bag with the sample tag number written and sealed and the other half of the sample kept for reference. QA/QC samples are inserted at a rate of one standard, one blank and one duplicate sample for each 20 samples collected. The insertion of QA/QC samples is performed by the geologist logging the samples.
2 All samples were sent to the Bureau Veritas laboratory in Vancouver and were checked against the custody chain form. The sample preparation includes weighing the sample, crushing 1 kg to minimum
3 QA/QC results including standards, blanks, duplicates and external checks did not reveal any issue or concern for this drill program.
