VANCOUVER – HighGold Mining has reported assays from another five drill holes in its nine-hole drill campaign at its Johnson Tract gold-copper-zinc property, 200 km southwest of Anchorage, Alaska.
The project has seen past work, including drilling, in the 1980s and 1990s, and the new drill results both confirm and expand upon historic results.
- Hole 85, which returned 59.2 metres (31.4 metres estimated true width) grading 15.06 g/t gold-equivalent (8.16 g/t gold, 5.9 g/t silver, 0.39% copper, 8.8% zinc and 0.72% lead) from 68 metres depth. This hole twinned a historic hole and was drilled for NI 43-101 validation purposes;
- Hole 86, which returned 47.6 metres (33.7 metres) of 9.52 g/t gold-equivalent (2.36 g/t gold, 4.8 g/t silver, 0.4% copper, 9.68% zinc and 0.13% lead) from 48 metres depth; and
- Hole 88, which hit 97.5 metres (48.8 metres) grading 9.52 g/t gold-equivalent (5.93 g/t gold, 4.2 g/t silver, 0.46% copper, 3.86% zinc and 0.62% lead) from 128 metres depth, including 22.5 metres of 16.24 g/t gold-equivalent.
Collectively, the new results demonstrate excellent continuity of thick zones of high-grade mineralization over a vertical dip length of over 250 metres.
HighGold reported on the first two holes drilled at JT in early November. Once it receives results from the final two holes of the program, HighGold plans to develop a 3-D geological model for the JT deposit and begin to put together the project’s first resource estimate.
“Drilling at Johnson continues to deliver impressive intersections and confirms the presence of a very robust mineralized zone,” said HighGold president and CEO, Darwin Green. “The widely spaced drill holes tested the JT Deposit over a vertical extent of 250 metres with excellent widths of high-grade mineralization intersected throughout. In addition to incremental expansion of the mineralized zone, the new data helps refine lateral and vertical zonation of precious and base metals, in which both gold grade and zone thickness increase with depth.”
He continued: “This bodes well for future exploration at the Northeast Offset target approximately 700 meters to the north, which we believe to be the off-set depth extension of the deposit.”
