Further details including tonnes, grade and assumptions are presented in the full Mineral Reserves and Mineral Resources table below while all Mineral Resources reported herein are exclusive of Mineral Reserves. The Proposed Transaction is expected to close by the end of the month.
Yamana also announces that it has filed its consolidated fourth quarter and year-end 2022 financial results, which are available under the Company’s profile on SEDAR at and on the Company’s website.
HIGHLIGHTS
- Track Record of Mineral Reserves Replacement: On an aggregate basis across its wholly-owned operations, the Company replaced gold mineral reserves by 104% of depletion highlighting the sustainability and longevity of its production platform.
- Continued Success of Mineral Reserve Growth at Jacobina: Jacobina had another year of mineral reserve and mineral resource growth, adding approximately 35,000 ounces of gold mineral reserves, or 117% of depletion. Gold mineral reserves have grown by 57% or more than 1 million ounces net of depletion over the past five years to 2.97 million ounces and mineral resources have increased by 80% over the same period, as detailed below. The track record of growth in mineral reserves and mineral resources at Jacobina underpins its significant prospectivity and geological upside.
- Conversion of Inferred Mineral Resources at Odyssey: At Odyssey, the ongoing infill drilling program continues to increase the inventory of indicated mineral resources to support the potential conversion of mineral resources to mineral reserves. Indicated gold mineral resources increased by over 3.81 million ounces to 6.17 million ounces with total inferred resources at year end of 9.23 million ounces (100% basis). 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 mineral resource envelope highlighting the generational nature of the deposit.
- Fifth Consecutive Year of Increasing Mineral Reserves at El Peñón: El Peñón achieved a fifth consecutive year of adding mineral reserves in excess of depletion, with mineral reserves growing 4% to 1.37 million GEO(1), or by 123% of depletion, over the last year.
- Company-wide Mineral Reserves and Mineral Resources Show Significant Scale: As at December 31, 2022, the Company reports 13.8 million ounces of gold mineral reserves and 112 million ounces of silver mineral reserves, relatively unchanged from the prior year. Further, the Company reports measured and indicated mineral resources of 17.1 million ounces of gold, 52 million ounces of silver, and 1.4 billion pounds of copper exclusive of mineral reserves, with measured and indicated gold mineral resources up 18% from the prior year. Inferred mineral resources contain 13.3 million ounces of gold, 60 million ounces of silver, and 2.13 billion pounds of copper. At the Company’s development projects, mineral reserves of 7.4 million ounces of gold, 57 million ounces of silver, and 6.7 billion pounds of copper represent significant upside potential within the existing portfolio.
YEAR END MINERAL RESERVES AND MINERAL RESOURCES SUMMARY
Canadian Malartic including Odyssey, Canada (50%)
The Canadian Malartic & Barnat Open Pit saw a decrease of approximately 263,000 ounces of gold in proven and probable mineral reserves (reflecting the Company’s 50% interest) driven primarily by depletion of 360,000 ounces of gold (50% interest) as the Canadian Malartic pit enters into its final years of operation and open pit mining transitions to the Barnat pit. With initial production from the underground Odyssey mine at Canadian Malartic having commenced earlier this month, an initial small portion of the indicated mineral resources at the Odyssey South deposit was converted to probable mineral reserves as at December 31, 2022, adding 98,000 ounces of gold in mineral reserves (50% interest). A substantial addition of mineral reserves is expected at the Odyssey project at year-end 2023 with the conversion of indicated mineral resources at the East Gouldie deposit where continued conversion drilling success resulted in the addition of 1.9 million ounces of gold in indicated mineral resources (50% interest) during the year.

(i) Adjustments for stockpile inventory variation and optimizations
At the Odyssey project, underground development remains on schedule with initial production and start of shaft sinking expected in March 2023. With only 0.4 million ounces of gold in indicated mineral resources and 6.9 million ounces of gold in inferred mineral resources, or approximately 47% of the Odyssey mineral resources included in the mine plan outlined in the March 2021 technical study on a 100% basis, there is significant upside potential to a mine life already expected to last until at least 2039. 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 flow 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.
Drilling demonstrates that the East Gouldie deposit also extends significantly to the west of the mineral resource envelope at significant 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. Thirteen drill rigs are currently active on the property, with five underground drills in the Odyssey South and Internal zones and eight surface drills focused on infilling and expanding the East Gouldie mineralization.
Jacobina, Brazil
Jacobina had another successful year of exploration, adding approximately 35,000 ounces of gold mineral reserves net of depletion, with additions of 239,000 gold ounces amounting to 117% of depletion. Gold mineral reserves have grown by 57% or more than 1 million ounces over the past five years to 2.97 million ounces. Mineral resources have increased by 80% over the same period, with mineral resources, exclusive of mineral reserves, increasing by 328,000 ounces of gold in measured and indicated mineral resources and 30,000 ounces of gold in inferred mineral resources versus the prior year. Mineral reserves average gold grade is unchanged from the previous year at 2.18 g/t. Highlights from 2022 include ongoing infill drilling success at João Belo Sul and Morro do Vento and successful exploration drilling at the new Morro do Vento Leste zone.

(i) Additions from infill drilling and new mine
Cerro Moro, Argentina
At Cerro Moro, mineral reserves changed due to 2022 depletion and adjustments to the geological models, partly offset by additions to the mineral reserves inventory from successful infill and delineation drilling. While gold ounces added by drilling covered annual depletion, an updated block model at Verónica caused an overall decrease of approximately 11,000 gold ounces. Depletion during 2022 was primarily from Zoe, a higher grade silver deposit, resulting in an overall decline of approximately 3.6 million silver ounces contained in mineral reserves.

(i) Gold Equivalent Ounces (GEO) calculated using mineral reserves metal price assumptions of $1,250 per ounce of gold and $18 per ounce of silver, and metallurgical recoveries of 94% for gold and 95% for silver.
El Peñón, Chile
Successful drilling at El Peñón resulted in the operation achieving a fifth consecutive year of adding new mineral reserves in excess of mining depletion, with mineral reserves growing 28% to 1.37 million GEO(1) over that period. The replacement of depletion maintains the El Peñón mine life at five to six years. Infill drilling, mainly at the Pampa Campamento and Martillo Flat veins, together with the conversion of underground mineral resources to mineral reserves at Chiquilla Chica, which is being reported for the first time, account for the replacement of gold ounce depletion and the increase of silver ounces contained in mineral reserves.

Minera Florida, Chile
At Minera Florida, new mineral reserves replaced mining depletion, extending the mine life. Gold ounces contained in mineral resources and mineral reserves have increased across most main zones with significant success at Maqui due to infill drilling and inaugural mineral reserves added at the Cucaracha zone.

Wasamac, Canada
Wasamac mineral reserves and mineral resources were updated in November 2022, with mineral reserves and mineral resources increasing 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%, while indicated mineral resources and inferred mineral resources have increased by 4% and 76% respectively.
The growth in mineral reserves and mineral resources is the result of infill drilling, the success of which has contributed to an updated mineral resource model and stope designs, with the average horizontal stope width increasing from 12.6 metres in 2021 to 13.6 metres in 2022.
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 mineral reserves life of nearly 10 years.
