Golden Dawn Minerals Inc (CVE:GOM) has filed its accompanying technical report for the Preliminary Economic Assessment (PEA) at its Greenwood gold project in British Columbia.
On base case numbers the internal rate of return is 72.6% and net present value C$32.5mln at a 6% discount rate and life of mine of five years.
After-tax, the internal rate of return is 61.5% and NPV C$23.2mln.
Pre-production capital requirements are C$9.7mln, with a life of mine cash cost of US$631 per oz gold and all-in sustaining costs of US$820 per oz.
Golden Dawn added there is potential to increase the resource on both Lexington and Golden Crown Mines, while feed may be shipped from the May Mac Mine 15 km by road from the Greenwood Mill.
Several satellite deposits too small to warrant stand-alone processing facilities may further increase mill feed, it said.
