TriMetals Mining Inc. said March 29 that it completed an updated pit-constrained mineral resource estimate for the Jumbo Trend, Grey Eagle zone and Thor zone of its Gold Springs gold-silver property, which straddles the Nevada-Utah border.
The updated estimate shows a 22% increase in measured and indicated gold resources as compared to 2015 figures, and an increase in the average reported gold grade. The majority of the resource is also located in the Jumbo Trend, which comprises the Jumbo North and Jumbo South blocks.
Using a cutoff grade of 0.25 g/t of gold, the blocks host 29.8 million tonnes at 0.55 g/t of gold and 10.0 g/t of silver for 527,687 ounces of gold and 9.6 million ounces of silver in the measured and indicated category.
Inferred resources, meanwhile, total 4.7 million tonnes at 0.46 g/t of gold and 6.49 g/t of silver for 69,484 ounces of gold and 972,708 ounces of silver.
According to the company, the new resource was based on drill information from 2015 and 2016 programs and uses capped assay data.
