Golden Dawn To Commence Underground Mine Work At Greenwood Precious Metals Project

VANCOUVER, BC--(Marketwired - August 22, 2017) - Wolf Wiese, President & CEO of Golden Dawn Minerals Inc. (TSX VENTURE: GOM) (FRANKFURT: 3G8A) (OTC PINK: GDMRF) (the "Company" or "Golden Dawn"), provides the following update on activities at the Greenwood Precious Metals Project.

Lexington Mine

The BC Ministry of Environment has given the Company the go ahead to dewater the Lexington mine upon giving 72 hours' notice, following the conditions outlined in the discharge permit and the Water Management Plan that was recently submitted. The Company is now working with its contractors to schedule the mine work and necessary environmental monitoring.

The dewatering program is estimated to take approximately four weeks and will be followed by an evaluation/mining program. Both of these programs will be carried out by a mining contractor. The dewatering program is expected to commence shortly, upon awarding the contract to a suitable Mining Contractor. Contractor bids have been received and are being reviewed by the company's consultants. Dewatering will consist of initial pumping at up to 1,000 cubic metres per day for 30 days, followed by continual pumping at 35 cubic meters per day.

Concurrent with dewatering, rehabilitation of the two ramps and surface mine infrastructure will take place. The ground support, mine electrical and ventilation services will be re-established to enable mining operations. The dewatering program will provide access to mine workings that were previously developed by Merit Mining in 2008. After dewatering, rehabilitation of mine workings will continue as will definition drilling, mapping and sampling of the workings toward assembling a test mine program.

Mining operations are planned to commence once the mine is dewatered to a sufficient level and services are installed. Test mining will target the mineralized zones between the 1,210m and 1,175m elevations, and the mining methods of longhole open stoping, jumbo mining and jackleg/slusher mining will be evaluated. Very little waste or zone development will be required to access the areas of the proposed test mining. During the test mining period, Golden Dawn will continue to evaluate the resources between these elevations, which could provide mill feed after the rehabilitation and dewatering of the Lexington Mine.
