The assays come from last year's program for 16,418 metres (m) in 32 holes and show the up-plunge extents of the deposit and also the continuity of the deeper Footwall Copper-Silver Zone (FCZ).

"We continue to be encouraged by the continuation and strength of the JT Deposit mineral system at depth and by the emergence of the Footwall Copper-Silver Zone, a new area of copper-silver rich mineralization, with resource potential that contributes to the overall metal endowment at Johnson," said CEO Darwin Green in a statement.
"The current batch of drill results are base-metal dominant and highlight the presence of copper and zinc-rich domains within the polymetallic gold-rich JT Deposit."
Highlights included 11m at 8.6% zinc, 0.4% copper, including 5m at 12.0% zinc, 0.3% copper in one hole, down plunge, and 12m at 2.8% copper, 51 g/t silver, within 58.6m at 1% copper, 21 g/t silver in another at the FCZ.
Green noted that drilling last year had "significantly" expanded the JT Deposit footprint with step-outs from the area, which hosts an indicated resource of 750,000 ounces of gold-equivalent at 10.9 g/t gold-equivalent.
"HighGold's geological and structural model continues to evolve. Based on the new data, it appears that a significant portion of the mineral system is open to expansion down-plunge and is not cut-off at depth as interpreted by previous operators," he added.
"With approximately C$18 million in the treasury, the company is fully funded to further test the limits of these zones and other targets in 2021.
Johnson Tract spans 21,000 acres and is a polymetallic (gold, copper, zinc, silver, lead) asset near tidewater in south-central Alaska. It hosts the high-grade JT deposit and at least nine other prospects over a 12km strike.
HighGold acquired the asset through a lease agreement with Cook Inlet Region, Inc (CIRI), one of 12 land-based Alaska Native regional corporations. CIRI is owned by more than 9,100 shareholders, who are primarily of Alaska Native descent.
