Superior Gold Inc. announces substantial growth in mineral reserves and resources
UNDERGROUND RESERVES MORE THAN TRIPLED
INCREASE IN RESERVES AND RESOURCES ACROSS ALL PROJECTS
TORONTO, April 3, 2018 /CNW/ - Superior Gold Inc. ("Superior Gold" or the "Company") (TSX.V:SGI) is pleased to announce the updated Mineral Reserve and Mineral Resource estimates as at December 31, 2017 for its Plutonic Gold Operations in Western Australia, which are comprised of the 100%-owned Plutonic underground gold mine, and 100%-owned Hermes open pit gold mine, along with the Company's interest in the Bryah Basin joint venture.
Comparisons are made to the prior Mineral Reserve and Mineral Resource estimates as described in a previously filed NI43-101 report dated September 30, 2016.
Highlights of the recent estimates include:
- Underground Mineral Reserves at the Plutonic mine more than tripled to 276,000 ounces grading 5.97 g Au/t, after mining depletion of approximately 125,000 ounces of gold from October 2016 to December 31, 2017
- The total Mineral Reserves across all projects doubled to 382,000 ounces
- Total Measured and Indicated Resources across all projects increased approximately 30% to 1.14 million ounces
- Total Inferred Resources across all projects increased more than 35% to 1.09 million ounces
Chris Bradbrook, President and CEO of Superior Gold stated: "We are extremely pleased to be able to provide this updated Mineral Reserve and Mineral Resource estimate, which we believe delivers on all the targets we have communicated to investors, the most important of which was to grow the underground Reserve and to demonstrate a longer term future for the Plutonic gold mine. This announcement is a good first step and we plan to provide a further Mineral Reserve and Mineral Resource update during 2018."
Mineral Reserves as at December 31, 2017 were estimated using a long term gold price of A$1,650 per ounce (US$1,287 per ounce). Mineral Resources as at December 31, 2017 were estimated using a long term gold price of A$1,700 per ounce (US$1,325 per ounce). Dilution of 10% was factored into the estimation of underground Mineral Reserves. Cut off grades for the Mineral Reserve and Mineral Resource estimates were 2.00 g Au/t for underground and 0.60 g Au/t for open pit.
