Diamond explorer Dunnedin Ventures ponders its B.C. gold-copper porphyry project

Primarily focused on Nunavut diamond exploration, Dunnedin Ventures TSXV:DVI has launched a technical and strategic review of its Trapper gold project in northwestern British Columbia.

The 40-square-kilometre property lies adjacent to Brixton Metals’ (TSXV:BBB) Thorn project and hosts the Ring zone “with over 10 kilometres of strike surrounding a porphyry centre, with gold-rich polymetallic mineralization drilled across 2.2 kilometres and associated surface copper porphyry showings,” Dunnedin stated.

Over $4 million of exploration included a 42-hole, 8,580-metre program completed in 2011. Some highlights showed:

Hole TG-11-011

  • 1.71 g/t gold, 5.6 g/t silver, 1.01% lead and 0.25% zinc over 34.11 metres, starting at 106.89 metres in downhole depth
  • (including 92.8 g/t gold, 18.8 g/t silver, 0.13% lead and 0.12% zinc over 0.41 metres)
  • (and including 3.9 g/t gold, 27 g/t silver, 9.11% lead and 0.91% zinc over 3.39 metres)

Hole TG-11-038

  • 1.68 g/t gold, 1.8 g/t silver, 0.02% lead and 0.07% zinc over 15 metres, starting at 122.5 metres
  • (including 5.08 g/t gold, 4.4 g/t silver, 0.05% lead and 0.13% zinc over 4.23 metres)
  • (which includes 21.8 g/t gold, 11.9 g/t silver, 0.15% lead and 0.36% zinc over 0.62 metres)

Hole TG-11-039

  • 1.01 g/t gold, 2.3 g/t silver, 0.02% lead and 0.13% zinc over 30 metres, starting at 67.5 metres
  • (including 2.19 g/t gold, 2.7 g/t silver, 0.06% lead and 0.3% zinc over 2.5 metres)
  • (and including 2.98 g/t gold, 4 g/t silver, 0.04% lead and 0.09% zinc over 2.5 metres)
  • (and including 2.64 g/t gold, 2.5 g/t silver and 0.35% zinc over 2.34 metres)

Hole TG-11-040

  • 1.19 g/t gold, 1.8 g/t silver, 0.01% lead and 0.07% zinc over 27.5 metres, starting at 132.5 metres
  • (including 11.15 g/t gold, 5.7 g/t silver, 0.03% lead and 0.17% zinc over 2.5 metres)

“The property overlies an unusually gold-rich porphyry copper complex including drill-ready copper porphyry and gold-rich semi-massive sulphide stockwork,” commented CEO Chris Taylor. “Dunnedin is conducting a comprehensive review of this 100%-owned project to determine how best to unlock its value for shareholders.”

The company has also been finding gold on its flagship Kahuna diamond project, with evidence from 2015 till sampling—just recently evaluated for gold—and from historic rock samples.

This year’s program collected 10 times as many till samples as 2015, gathering 1,111 samples to be analyzed for diamond indicator minerals and gold. The company also staked another 25,000 hectares, increasing Kahuna to about 60,000 hectares.
