Golden Dawn Minerals to refurbish former B.C. gold-silver-copper mine and mill for trial operation

by Greg Klein | September 28, 2017

Slated to begin imminently, a dewatering and rehab program could help Golden Dawn Minerals TSXV:GOM bring new life to a southern British Columbia past producer. Under a previous operator the former Lexington mine produced 5,486 ounces of gold, 3,247 ounces of silver and 860,259 pounds of copper from April to December 2008. Processing took place about 17 kilometres away at the Greenwood mill. With a 212-tpd capacity expandable to 400 tpd, the mill now comprises an important asset in Golden Dawn’s portfolio of nearby former mines.

Built in 2007 only to be shuttered months later by the downturn,
the Greenwood mill holds a key position in Golden Dawn’s plans.

Lexington’s rehab will focus on two declines prior to installing electrical service and ventilation. The agenda then calls for mapping, sampling and definition drilling to support test mining.

A 2016 resource used a base case 3.5 g/t gold-equivalent cutoff, giving Lexington:

  • measured: 58,000 tonnes averaging 6.98 g/t gold, 1.1% copper and 8.63 g/t gold-equivalent for 16,100 gold-equivalent ounces

  • indicated: 314,000 tonnes averaging 6.38 g/t gold, 1.04% copper and 7.94 g/t gold-equivalent for 80,200 gold-equivalent ounces

  • inferred: 12,000 tonnes averaging 4.42 g/t gold, 1.03% copper and 5.96 g/t gold-equivalent for 2,300 gold-equivalent ounces

Although Lexington remains the company’s current priority, surface drilling continues on the company’s Golden Crown property, host to the Greenwood mill. Fifteen holes have been completed so far, with a plan to further delineate and extend the project’s 2016 resource. Using a 3.5 g/t gold-equivalent cutoff, the estimate shows:

  • indicated: 163,000 tonnes averaging 11.09 g/t gold, 0.56% copper and 11.93 g/t gold-equivalent for 62,500 gold-equivalent ounces

  • inferred: 42,000 tonnes averaging 9.04 g/t gold, 0.43% copper and 9.68 g/t gold-equivalent for 13,100 gold-equivalent ounces

Another summer drill program at May Mac, another past producer, wrapped up with eight surface holes totalling 1,886 metres. One interval found 1.13 g/t gold, 23 g/t silver and 0.7% lead over 0.36 metres starting at 204.34 metres in downhole depth. Another intersection revealed previously unknown copper, grading 0.24% over 0.79 metres starting at 45 metres in depth.

Following up on a spring campaign, the program showed May Mac’s Skomac vein system extending at least 215 metres beyond the former mine’s workings. Golden Dawn now has permitting underway for underground drilling to avoid the topographical challenges encountered over the extension.

As for the mill, contractors agree the 2007-built facility “is in excellent shape,” Golden Dawn stated. Estimates call for about $270,000 and three to five weeks to put the plant back into operation. The company anticipates that happening as feed becomes available from the Lexington mine.

Golden Dawn also spent the summer prospecting additional former mine sites and mineral showings on other holdings within an approximately 15-kilometre radius of the mill.

Given the portfolio’s existing resources, infrastructure and potential, Golden Dawn hopes to enter production without de-risking at the feasibility level. The properties lie approximately 500 kilometres by highway east of Vancouver.

Earlier this month the company closed a $2-million private placement first tranche. Subject to approvals, Golden Dawn expects to close an additional $640,000.
