TORONTO, Nov. 10, 2022 (GLOBE NEWSWIRE) -- YAMANA GOLD INC. (TSX:YRI; NYSE:AUY; LSE:AUY) (“Yamana” or the "Company”) is pleased to announce new exploration drilling results across its asset portfolio, underscoring its strategic outlook and efforts to meaningfully extend and expand its sustainable production platform. Exploration results at Canadian Malartic, Wasamac and Jacobina support strong organic growth in mineral reserves, mineral resources and production through successful brownfield exploration programs. Further success at El Peñón, Minera Florida and Cerro Moro is expected to significantly replace or reduce depletion due to mining, extending mine life, increasing sustainable production and enhancing asset value.
The Company is also pleased to report that the strong operational performance seen throughout the nine month period ended September 30 continued in the month of October. This overwhelmingly strong production performance significantly exceeded plan and positions the Company for a strong finish to the year, well within guidance expectations. The Company produced 88,739 gold equivalent ounces ("GEO")(1) in October, with gold production near a monthly high of the year at 79,472 ounces and silver production near a monthly high of the year at 796,573 ounces. With both gold and silver production coming in well ahead of plan, GEO(1) production in October was the second strongest monthly production so far this year. The standout GEO(1) production also notably reflects a gold-to-silver ratio which is near an all-time high and significantly above that assumed in guidance. The results reflect continued operational strength at all of the Company’s operations with standout performances at Canadian Malartic with 30,943 GEO(1) (50% attributable basis), El Peñón with 19,249 GEO(1) and Cerro Moro with 14,644 GEO(1).

Notable exploration highlights include:
- Significant progress on the conversion of inferred mineral resources to indicated mineral resources at East Gouldie and Odyssey South with infill drilling continuing to meet or exceed the grade and width of the reported inferred mineral resource. Updating of the mineral resource model with the new drill holes has commenced and is expected to result in the conversion of a significant portion of the inferred mineral resource declared in 2021 to indicated mineral resources by the end of 2022. Exploration drilling at the East Gouldie zone of the Odyssey mine also continues to grow the mineralized footprint with new intercepts to the west of the known resource envelope highlighting the generational nature of the deposit.
- Wasamac's mineral reserves and mineral resources have grown significantly, with gold mineral reserves increasing by 14%. Wider than expected intervals in some core zones, significant infill drilling as well as the delineation of new mineralized zones have contributed to an updated resource model at Wasamac, with increases in probable mineral reserves, indicated mineral resources and inferred mineral resources. The updated resource model supports an expanded gold production scenario at 9,000 tonnes per day (“tpd”) which contemplates an early ramp-up to 200,000 ounces in 2027 and up to 250,000 ounces in 2028. The inferred mineral resource expansion and exploration programs are ongoing and further results are expected by year-end.
- Exceptional results are being produced by Jacobina's expanded drilling program. Strong mineral resource growth in the new and rapidly growing João Belo Sul zone as well as a pending maiden inferred mineral resource for part of the Morro do Vento Leste zone continue to highlight the long-term upside potential at Jacobina. The results are expected to continue the strong track record of mineral reserve and mineral resource growth at Jacobina which supports the recently completed Phase 2 expansion and the planned Phased 3 expansion which will allow for production of up to 270,000 ounces of gold per year.
- Solid exploration results at El Peñón, Minera Florida and Cerro Moro. Drill programs at El Peñón, Minera Florida and Cerro Moro designed to replace depletion due to mining and the solid exploration results reported in this release suggest that the sites are on track to meet this target for the year.
Infill drilling of the East Gouldie and Odyssey South deposits continues to meet or exceed the grade and width of the reported inferred mineral resource. It is expected that a significant portion of the inferred mineral resources declared in 2021 will be converted by the end of 2022 into indicated mineral resources as a result of updating the mineral resource model with the new drill holes. These new indicated mineral resources will provide the basis for updated technical studies that will allow the definition of mineral reserves for the Odyssey underground project over the next few years. The Company expects the definition of mineral reserves for the Odyssey underground project to start at the end of 2022, supporting first gold production from Odyssey South in the first quarter of 2023.
Additionally, drilling continues to delineate the Odyssey internal zones, which were not previously considered in the 2021 preliminary economic assessment mine plan. The Odyssey team is in the process of optimizing the mine plan with these drilling results, which is expected to result in higher gold production during the construction period, further offsetting the initial capital cost and optimizing the cash flows profile starting in 2023.
As previously reported, exploration drilling of the East Gouldie Extension and parallel Titan zone indicate that a corridor of mineralization extends at least 1.3 kilometres to the east of East Gouldie and over an approximate 2,000 metre vertical extent. The Company believes that the underground development will support a significantly higher level of production than assumed in the current mine plan with more production that could come from further ramp development and from a possible second shaft at depth where mineralization remains open in all directions.
New drilling demonstrates that the East Gouldie deposit also extends significantly to the west of the resource envelope at economically favourable grades and widths. Overall, drilling indicates that the East Gouldie deposit extends more than 4 kilometres along strike, of which only approximately 1.5 kilometres is currently reported as mineral resources.
Year to date, 68,541 metres of infill drilling at East Gouldie have been completed with ten to twelve drill rigs. Infill drilling continues to convert as expected with predictable wide zones at expected grades. Highlights include: MEX 21-219ZB with 9.68 g/t of gold (9.65 g/t of gold cut to 20 g/t) over an estimated true width of 30.90 metres, MEX21-224WAZ with 4.57 g/t of gold over an estimated true width of 50.70 metres and MEX 22-235Z with 6.18 g/t of gold over an estimated true width of 31.00 metres.
Infill drilling on the Odyssey South zone totals 32,300 metres to date with significant mineralization observed in internal higher grade zones including the following highlights: UGOD 16-075 with 6.80 g/t of gold (5.69 g/t of gold cut to 20 g/t) over an estimated true width of 21.84 metres and UGOD 16-071 with 15.31 g/t of gold (11.29 g/t of gold cut to 20 g/t) over an estimated true width of 5.70 metres. See Figure 1 and Table 1 for additional drill results.
Exploration drilling on the East Gouldie corridor includes 12,405 metres of drilling year-to-date in 2022. Step out drilling west of the East Gouldie mineral resource has generated several positive new intercepts expanding the potential of the East Gouldie zone highlighted by hole MEX22-240 with 4.19 g/t of gold over an estimated true width of 12.80 metres at 1,331 metres depth in an area approximately 670 metres west of the current East Gouldie mineral resources.

Drilling through the remainder of 2022 and into 2023 will complete the mineral resource conversion of the core mineralized zone at East Gouldie, explore the up dip and western extensions of the known East Gouldie envelope and continue to convert mineral resources to indicated mineral resources at Odyssey South with infill drilling.
To date all results support the planned underground Odyssey project with significant upside in extensions of the East Gouldie zone across a very large mineralized panel and in extensions and within internal higher grade zones in the advancing Odyssey South project. Notably, the Company also recently received the requisite mining lease from the Quebec Ministry of Natural Resources and Forestry and the Certificate of Authorization to commence underground mining. As such, all required permits to commence gold production from the Odyssey mine have now been obtained.
Wasamac mineral reserves and mineral resources have increased across all categories and by a total of 19% since completion of the feasibility study in mid-2021. Mineral reserves have increased by 260,000 ounces or 14% (Table 3), while indicated mineral resources and inferred mineral resources have increased by 4% and 76% respectively (Table 4).
The growth in mineral reserves and mineral resources is the result of infill drilling, with 30,242 metres completed year-to-date, concluding the drill program for the year. Results are positive with both wider than expected mineralization in some sectors of the existing mineral reserves and the definition of several new mineralized zones in the hanging wall of the deposit (Table 2; Figure 2). These results have contributed to an updated resource model and stope designs, with the average horizontal stope width increasing from 12.6 metres in 2021 to 13.6 metres in 2022. As such, the additional mineral reserves are expected to be accessible at a lower unit cost, with an improved ratio of gold ounces per development metre.
The positive results support the expanded production plan at 9,000 tpd, with a gold production profile of 200,000 to 250,000 ounces per year compared to the LOM average of 169,000 ounces in the 2021 feasibility study, while maintaining a reserves life of nearly 10 years. With conversion of mineral resources and exploration potential, the Company is confident that mine life will extend at least 15 years. Additionally, 47 new infill drill holes within the indicated mineral resource envelope provides a high level of geological confidence, supporting the first three years of production.
The Wasamac deposit remains open at depth and along strike and the underexplored secondary zones such as Wildcat are showing promising drilling results. Follow up exploration drilling at Wildcat and Wildcat south totaling 4,266 metres has been completed in 2022. Additional exploration targets on the property, including the adjacent Francoeur, Arntfield, and Lac Fortune properties, provide further potential upside. Exploration drilling of potential mineral envelopes defined by historic drilling at Francoeur and Arntfield totaling 7,232 metres has been completed in 2022. Results are pending for the exploration drilling.

- Mineral resources have been estimated by Dominic Chartier, P.Geo., a full-time employee of Yamana Gold Inc., and a qualified person as defined by NI 43-101. The estimate conforms to the CIM (2014) Standards and the CIM (2019) Guidelines. Mineral resources were estimated using ordinary kriging informed by capped composites and constrained by three-dimensional mineralization wireframes. Classification was completed following a distance-based criteria determined by grade continuity observed from variography.
- Mineral resources are not mineral reserves and have not demonstrated economic viability.
- Underground mineral resources are estimated at a variable cut-off grade of 1.14 to 1.42 g/t Au, which corresponds to 75% of the mineral reserves cut-off grades. Mineral resources are reported fully diluted within conceptual mining shapes. Bulk densities ranging from 2.77 g/cm3 to 2.81 g/cm3 were used to convert volume to tonnage.
- All figures are rounded to reflect the relative accuracy of the estimate.
Exploration drilling at Jacobina ramped up significantly in 2022, supported by a budget of $15 million. Through the end of the third quarter, 38,900 metres of drilling had been completed. Conversion of inferred mineral resources to indicated mineral resources, supported by 23,600 metres of infill drilling, was completed at Morro do Vento and João Belo Sul as well as the north extension of João Belo with additional step out and exploration drilling at both zones. Morro do Vento and Morro do Vento Leste are both expected to contribute to new inferred mineral resources for year-end updates and modelling. João Belo Sul is expected to provide significant new indicated mineral resources and inferred mineral resources only two years after discovery of the zone and following definition of a maiden inferred mineral resource in 2021. This zone continues to exhibit large scale potential with exploration drilling now identifying potentially economic mineralization along 3.1 kilometres of strike length (Figure 3).
Recent drilling highlights from João Belo Sul include the following estimated true width intervals: 8.22 g/t of gold over 2.10 metres (hole JBS00012); 5.15 g/t of gold over 3.04 metres, including 10.04 g/t of gold over 1.38 metres and 6.75 g/t of gold over 2.30 metres, including 10.27 g/t of gold over 0.92 metres in drill hole JBS00013; 15.20 g/t of gold over 1.15 metres and 3.90 g/t of gold over 2.98 metres, including 6.81 g/t of gold over 1.56 metres in drill hole JBS00008; and 6.67 g/t of gold over 2.94 metres, including 18.16 g/t of gold over 0.93 metres and 3.26 g/t of gold over 3.95 metres in drill hole JBS00021. This new mineralized zone is expected to continue to demonstrate growth over the next decade of mining at Jacobina.

Morro do Vento Leste is a large mineralized zone which extends vertically from approximately 300 metres to 900 metres below surface in the eastern portion of the mine. This zone has seen limited infill drilling to date but the completion in 2022 of 3,280 metres in six drill holes will allow a portion of the mineralized area to be defined as inferred mineral resources for year end, the first step in providing the next generation of indicated mineral resources for a growing eastern mine complex. Drilling highlights from Morro do Vento Leste include estimated true width drill intervals 4.26 g/t of gold over 2.57 metres (drill hole MVE00004) and 4.35 g/t of gold over 3.19 metres, including 14.51 g/t of gold over 0.62 metres in hole MVE00006.
Exploration also continues to expand the mineralized trend to the north of Canavieiras with positive drill results reported from exploration at Viuva and Maricota. At Maricota, drill hole MRCEX00001A returned a positive result of 7.56 g/t of gold over an estimated true width of 2.37 metres at 417.5 metres down hole, confirming the down-plunge continuation of mineralization at surface, and opening up this target for further exploration down plunge as far as historic drill hole MVTEX22 (9.72 g/t of gold over 1.80 metres). (See Table 5 for additional drilling results).

The Company expects these drilling results to translate into another year of significant mineral reserve and mineral resource growth at year-end. Mineral reserves and mineral resources have grown by approximately 68% over the past five years, net of depletion, unlocking the ability of the underground mine to support the Phase 2 expansion to 230,000 ounces of gold per year, which was completed in the third quarter.
Exploration drilling resulted in maiden mineral resources at João Belo Sul in 2021 and is expected to result in maiden mineral resources at Morro do Vento Leste at the end of this year. These two new additional deposits are expected to not only extend mine life, but provide additional sectors to be mined in parallel with the existing underground mines, supplementing the existing mine production rate and facilitating further expansion phases. Both João Belo Sul and Morro do Vento Leste can be accessed from the existing mine with modest underground development and infrastructure requirements. The Company has now begun pursuing the Phase 3 expansion to 10,000 tpd through continued incremental debottlenecking. With the permit to 10,000 tpd already in hand, Phase 3 is expected to increase gold production to approximately 270,000 ounces per year. The Phase 4 expansion, of up to 15,000 tpd, would increase gold production in excess of 350,000 ounces per year.
El Peñón, located approximately 165 kilometres southeast of the city of Antofagasta in northern Chile, is a high-grade underground gold-silver mine. The operation has a strong track record of mineral reserve replacement, continually replacing ounces mined since entering production in 1999. El Peñón highlights Yamana’s ability to deliver value and organic growth by consistently replacing mineral reserves beyond depletion and increasing mine life. This record of exploration success continued in the second half of 2022 with continued success expanding multiple core mine structures.
Exploration at El Penon has focused on replacing mineral resources and mineral reserves due to mining depletion and mineral resource conversion drilling. Exploration and infill drilling totalling 59,359 metres was completed in 11 sectors of the core mine. Drilling continued to focus on sectors that were most productive in generating new mineral resources during 2021, following higher grade trends, extending mineralization to depth within the lower dacitic unit across shallowly dipping faults, and on parallel and secondary veins associated with known structures (e.g., Pampita, Martillo Flat Sur Este). Results are positive to date with good intercepts in the Pampa Campamento, Pampita, Martillo Flat, Ventura and Dorada veins which are expected to deliver new indicated mineral resources for year end.

After completing drilling at the Penon Sur discovery in the second quarter of 2022 and having recently developed a full three dimensional geological, geochemical and structural model, the Company will now focus on advancing underground drill access and generating priority targets available for drilling planned in 2023.
El Peñón, which achieved a fourth consecutive year of adding mineral reserves in excess of depletion with mineral reserves increasing 23% to 1.3 million GEO(1) over that period, represents another source of value creation for the Company as it continues to extend the mine life at a production rate of 220,000 to 230,000 GEO(1) per year. Daily throughput is now approximately 3,300 tpd versus the currently available plant capacity of up to 4,200 tpd, representing an opportunity to increase production as the operation endeavours to build its mineral inventory in wake of consistent exploration results.
The 2022 exploration program at Minera Florida is focused on replacing depletion due to mining and on building a strong inventory of new inferred mineral resources that will open new mine sectors and provide a possible path to production expansion. Infill drilling year-to-date totaling 22,569 metres, utilizing four underground drill rigs and one surface diamond drill rig, was completed in several core mine areas and positive results were received from Aurora, Bandolera, Patagua W and elsewhere. At Aurora, high-grade mineralization remains open for expansion to depth. Drill highlights from the Aurora Vein include the following estimated true width intercepts: 12.07 g/t of gold, 54.6 g/t of silver and 0.13% of zinc over 2.87 metres (ALH3790); 19.79 g/t of gold, 53.9 g/t of silver and 0.15% of zinc over 1.70 metres (ALH3846); 7.71 g/t of gold, 32.7 g/t of silver and 1.78% of zinc over 2.35 metres (ALH3804).
Exploration drilling totalling 17,533 metres utilizing two underground drill rigs tested several target areas during the year, including Maqui Norte, Manda Norte, Maqui CII, Cantillana, Circular, Cucuracha, Lisette, Lisette Sur, Milenium, Satelite Manda, Diablita, Las Lauras, Maqui, Don Leopoldo, Peumo, Polvorin and VCN. High-grade intercepts were reported at Maqui Norte, where mineralization remains open for further expansion laterally to the north, and at Manda Norte, where mineralization remains open down dip, and where drilling results to date suggest grades may increase with depth.
Highlights from Maqui Norte include the following estimated true width intervals: 8.51 g/t of gold, 7.8 g/t of silver and 2.95% of zinc over 2.85 metres in drill hole ALH3793; and 6.22 g/t of gold with 3.2 g/t of silver over 1.79 metres in hole ALH3691. Highlights from Manda Norte, proximal to existing underground infrastructure, include the following estimated true width intercepts: 39.01 g/t of gold, 7.9 g/t of silver and 1.21% of zinc over 2.57 metres and 5.49 g/t of gold, 3.5 g/t of silver and 0.88% of zinc over 2.42 metres in drill hole ALH3664; 11.88 g/t of gold, 20.7 g/t of silver and 12.02% of zinc over 1.42 metres in hole ALH3799; 6.84 g/t of gold, 3.8 g/t of silver and 1.05% of zinc over 1.60 metres in drill hole ALH3668; 7.57 g/t of gold, 10.7 g/t of silver and 5.04% of zinc over 1.50 metres in hole ALH3817; and 8.93 g/t of gold and 4.5 g/t of silver over 1.14 metres in hole ALH3658. Results to date are positive with promising result for new potential indicated mineral resources and inferred mineral resources in both the core mine, the new Pataguas sector and along the Maqui fault structure.

Consistent with the 10-year outlook, the Minera Florida plant de-bottlenecking study is advancing on schedule, with the objective to increase throughput from 74,500 to 100,000 tonnes per month in 2025, thereby increasing annual gold production to approximately 120,000 ounces. The Company submitted the ESIA for the expansion during the fourth quarter of 2021, with the timeline expected to be approximately 18 months for approval, with another 12 months to receive sectoral permits.
Cerro Moro exploration during 2022 has largely been concentrated in the core mine and Naty sectors with infill drilling targeting extensions of known mineralization both to depth and along strike to replace mining depletion. Infill drilling to date totaling 13,658 metres returned positive results at Escondida West, Veronica, Gabriela, Naty and Zoe. Highlights include the following estimated true width intervals: 63.24 g/t of gold and 206.3 g/t of silver over 1.82 metres (MD3842); 28.32 g/t of gold and 1,164.4 g/t of silver over 4.85 metres (MD3783); 53.17 g/t of gold and 719.1 g/t of silver over 0.87 metres (MD3983); 20.91 g/t of gold and 173.3 g/t of silver over 8.25 metres (MD3612); and 15.55 g/t of gold and 2,155.4 g/t of silver over 2.34 metres (MD4089). The infill program will continue at Gabriela, Martina, Naty, Michelle, Nini, Domos Union and Esperanza in the fourth quarter.
Exploration drilling completed to date included 17,800 metres of diamond drilling largely continuing to focus on the core mine Escondida-Zoe structural corridor, continuing to test extensions of known ore shoots to depth and laterally and to test new sectors, targeting areas with potential to generate new underground mineral resources. Drilling utilizing two diamond drill rigs was completed and results received during the quarter include positive intercepts from Escondida West, Escondida Far East, Veronica, Zoe and Gabriela, extending ore shoots laterally and to depth at both targets. At Escondida Far East, drilling targeted the down plunge extensions of steeply plunging high grade ore shoots in the southeastern sector of this zone. Highlights include the following estimated true width intervals: 532.18 g/t of gold and 113.2 g/t of silver over 0.57 metres (275.28 g/t gold diluted over 1.10 metre mining width) (MD3598); 45.03 g/t of gold and 3,246.9 g/t of silver over 2.53 metres (MD3532); 44.24 g/t of gold and 187.6 g/t of silver over 1.56 metres (MD3529); 10.59 g/t of gold and 429.2 g/t of silver over 4.74 metres (MD3981); and 176.95 g/t of gold and 399.4 g/t of silver over 1.15 metres (MD3562).

The mine has a significant inventory of veins that are comparatively lower-grade in relation to the very high Cerro Moro mineral reserve and mineral resource grade, that are not fully reflected in the current mineral reserve and mineral resource statements. These veins could potentially support new mineral resources for the plant expansion scenario with lower cut-off grades than the high grades currently being mined. Drilling of these lower grade veins was not typically followed up with infill drilling in the past as the mineralization is below the current cut-off grade. Cerro Moro was developed as a high grade, low tonnage operation but, from the beginning, the Company has considered alternative processing options to allow for economic extraction of lower grade mineralization, including:
a) a scalable plant, where the front-end of the plant anticipates higher 2,000 tpd tonnage, with the expectation of modest capital requirement to achieve this objective,
b) heap leaching near surface, lower-grade material to supplement other production.
The objective at Cerro Moro is to create a sustainable ten years of production of at least 160,000 GEO(1) per year, and up to 200,000 GEO(1) per year. Upside from the aforementioned processing options would be beyond the current ten-year outlook that assumes Cerro Moro as a 150,000 to 165,000 GEO(1) per year operation, which is expected to be sustainable from mineral reserves mine life, ongoing exploration successes and mineral reserve replacement.

Quality Assurance, Quality Control and Data Verification
Yamana incorporates a Quality Assurance and Quality Control (“QA/QC”) program for all of its mines and exploration projects which conforms to industry best practices.
Samples are transported in security sealed bags for preparation at Geoassay, SGS and ALS Geochemistry. ALS and SGS are both ISO 9001:2008 and 17025 certified laboratories. Gold is analyzed by gold fire assay with 30 grams aliquot and AAS finish (lab code: Au-AA25). Au-AA25 is certified from 0.01 to 100 g/t gold. Samples over 100 g/t gold are re-analyzed by gravimetric finish methods. Silver is determined using a four acid digestion and ICP-MS finish (ultra trace). The ME-MS61 method we use for silver is certified 0.01 to 100 ppm. Five percent of all pulps are further checked by a secondary certified laboratory (SGS) using the same ore grade fire assay analytical method.
All exploration diamond drill cores are split in half by core sawing and sampled at appropriate intervals for assay. The remaining core, and pulps are stored on-site in a secure location. We disposed of the rejects at the lab after the QA/QC was complete.
Certified reference standards, blanks and duplicates (preparation and analytical) are routinely inserted into the sample stream as a control for assay accuracy, bias, precision and contamination. The results of these checks are tracked and failures are re-analyzed. This information also includes pulp checks carried out in the secondary lab.
