GoldMining Updates Mineral Resource Estimate with Inclusion of Antimony at its Crucero Gold Project, Peru
Highlights:
- Indicated Mineral Resource: 42.7 million tonnes ("Mt") at 1.26 grams per tonne ("g/t") gold equivalent ("AuEq") for 1.74 million ounces ("Moz") AuEq.
- Inferred Mineral Resource: 34.9 Mt at 0.93 g/t AuEq for 1.04 Moz AuEq.
- For the first time, antimony ("Sb") is modeled in the MRE and contributes approximately 25% of the Indicated AuEq oz and 29% of the Inferred AuEq oz.
- Estimated gold equivalent ounces in the Indicated category have increased by approximately 75% compared to the prior MRE from 2017*.
- The MRE is reported within a conceptual pit shell for the Project using long-term average prices of
US$3,110 /oz for Au andUS$28,700 /t for Sb.
Alastair Still, Chief Executive Officer of GoldMining, commented: "We are excited to update the Mineral Resource Estimate at Crucero, which has for the first time incorporated antimony, a critical metal globally recognized for its strategic importance. On a gold equivalent basis we have expanded Indicated resources by approximately 75% using a long-term average gold price of

Exploration programs from 1996 to 2012 conducted by previous operators included geological mapping, soil and rock geochemistry, trenching, surface geophysical surveys, diamond drilling (79 holes over 24,773 m) and metallurgical testwork. Drilling was concentrated on one of the geophysical anomalies referred to as the
To date, exploration of the Project has concentrated on the

Notes:
- Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the Mineral Resources estimated will be converted into Mineral Reserves.
- Open pit resources stated as contained within a conceptual open pit above a 0.30 g/t AuEq cut-off.
- Pit constraints are based on an assumed gold price of
US$3,110 /oz, an antimony price ofUS$28,700 /tonne, metallurgical recoveries of 90% for gold and antimony, mining cost ofUS$2.50 /t and processing cost ofUS$20.00 /t. - Mineral resource tonnage and contained metal have been rounded to reflect the accuracy of the estimate, and numbers may not add due to rounding.
- Mineral resource tonnages and grades are reported as undiluted.
- Contained metal grades are in-situ and do not include process recovery losses.
- CIM (2014) definitions were followed for classification of Mineral Resources.
- AuEq (g/t) = Au grade (g/t) + (2.87 * Sb grade (%) x 90% recovery)
