First Test of 2021 Shows Johnson Tract Exploration Potential North of 60th Mining News – September 17, 2021
On September 14, HighGold Mining Inc. cut heavy mineralization in the first resource expansion hole of the JT deposit, as assay results begin to arrive from the company’s 2021 program on the Johnson Tract polymetallic gold project in the south-central Alaska.
According to a calculation made in April 2020, the JT deposit contains 2.14 million metric tons of indicated resources with an average of 6.07 grams per metric ton (417,000 ounces) of gold, 5.8 g / t (397 000 oz) silver, 5.85% (275.3 million pounds) zinc, 0.57% (26.8 million pounds) copper and 0.71% (37.6 million pounds) lead .
During the 2020 season, and after the resource was calculated, HighGold completed 32 holes to expand this deposit and test other targets in the immediate area.
Highlights of the 2020 drill intersections on the margins of the JT deposit mineral resource area include:
• 74.1 meters containing on average 17.89 g / t gold, 7.1 g / t silver, 0.48% copper, 7.28% zinc and 1.31% lead in the hole JT20-092.
• 75.1 meters containing on average 10.01 g / t gold, 6 g / t silver, 0.57% copper, 9.36% zinc and 1.11% lead in JT20-093.
• 20.1 meters containing on average 11.5 g / t gold, 4 g / t silver, 0.5% copper and 3.1% zinc in JT20-096.
Building on the success of the 2020 drill program, the 2021 program’s first hole, JT21-123, cut 4.3 meters with an average of 13.1 g / t gold, 200 g / t silver , 4.92% zinc, 2.04% lead and 0.35% copper.
“This is a great start to the 2021 drill program,” said Darwin Green, President and CEO of HighGold Mining. “Our first drill hole of the season intersected strong precious and base metal mineralization in a big step up from last year’s drilling, increasing the total length of mineralization at the JT deposit by 15-20% at 600 meters. In addition to the excellent gold grades, the intersection includes some of the highest silver grades documented to date at the JT deposit and is developed in a mudstone host – features often found in gold-rich VMS deposits. . “
Mineralization encountered in hole JT21-123 is hosted in a unit of fine-grained mudstone similar to the “VMS style” mineralization reported last season in hole JT20-114, which intersected 7.8 meters with an average of 6.1% zinc, 1.6% lead, 0.2% copper, 0.7 g / t gold and 36 g / t silver approximately 600 meters northeast of the JT deposit.
HighGold says mineralization mined in JT21-123 highlights overall exploration potential at Johnson Tract.
“We are already designing follow-up holes and are excited to see how this new variation in the style of mineralization at the JT deposit develops as we continue to test at depth and along strike,” said Green.
Although HighGold is more than half of the 20,000 meters of drilling planned for 2021 at Johnson Tract, the results from hole JT21-123 mark the first results of this large program.
So far this year, the company has completed 11 holes in the target area of the JT deposit and 15 holes at DC Prospect, one of several regional targets located along a 7.5 mile (12 kilometer) trend. running through the Johnson Tract project.

Upon completion and receipt of all assays from the 2021 drilling program, HighGold will have completed a recalculation of resources that incorporates all new drilling completed at Johnson Tract in 2020 and 2021.
