Confirmed and possible reserves at Mesquite are unique of assets. Reserves whole 30.3 million tonnes grading 0.48 g/t gold for 471,000 oz. of contained gold.
Equinox primarily based its Mesquite estimates on 20,230 metres of drilling finished over the past half of 2020, and the numbers don’t embrace any outcomes for the 2021 program.
Drilling at Fazenda efficiently changed underground and pit reserves on an annualized foundation, with the outcomes of 155,008 metres drilled from Could 2018 to Dec. 31, 2020. After mining 196,000 oz. throughout that interval, Equinox says the reserves are just about unchanged. Confirmed and possible reserves now stand at 6.6 million tonnes with a median grade of 1.47 g/t gold for 315,000 oz. of contained gold.
The measured and indicated assets (unique of reserves) whole 5.2 million tonnes with a median grade of 1.77 g/t gold for 294,000 oz. of contained gold. The inferred useful resource is 3.3 million tonnes with a median grade of 1.5 g/t gold for 158,000 oz. of contained gold.
110,000-metre drill program
This yr, Equinox started a 74,000-metre drill program at Fazenda to exchange reserves and check greenfield targets within the 70-km-long Fazenda-Santa Luz mining district. Mixed with near-mine and regional exploration across the Santa Luz mine (on account of pour its first gold early subsequent yr) to the north, the corporate plans to finish greater than 110,000 metres of drilling this yr to additional outline the district.
The Riacho Dos Machados (RDM) open-pit gold mine numbers embrace 42,654 metres of grade management drilling finished from Could 2018 to Dec. 31, 2020, in addition to a reinterpretation of the block mannequin. Confirmed and possible reserves are 17.6 million tonnes grading 0.99 g/t gold for 556,000 oz. of contained gold. The numbers characterize a 30% drop in metallic content material after 173,000 oz. of gold was mined throughout the interval.
The measured and indicated assets (unique of reserves) at RDM are 3.2 million tonnes grading 1.27 g/t gold for 132,000 oz. of contained gold. The inferred portion is 3.6 million tonnes grading 1.95 g/t gold for 226,000 oz. of contained gold.
Equinox acquired the RDM gold mine in 2020 with the takeover of Leagold Mining. The corporate has targeted on operational enhancements together with connection to the ability grid and plant optimizations which have boosted throughput and recoveries. Subsequent yr’s exploration program will likely be aimed toward rising assets.
With seven producing mines and 4 development initiatives within the Americas, Equinox has set a purpose of manufacturing 1 million oz. of gold yearly. The 2021 manufacturing steerage is for about 600,000 oz. at an all-in sustaining price of $1,300 per ounce.
