US-based Silver Falcon Mining has restarted operations at its 100%-owned Sinker Tunnel Gold Project in Idaho after a 100-year hiatus.

The news follows the company’s announcement last month that all administrative requirements to the US Mine Safety and Health Agency had been approved.

Following preparations carried out over two years, the Sinker Tunnel, located in the Oro Fino Vein system in the War Eagle Mountain, is now open and Silver Falcon has begun aeration and bolting of the remaining upper wall of the existing tunnel.

The company has commissioned equipment required at the mine and is set to commence a 5,000-feet core drilling programme.

Silver Falcon expects to release results from the exploratory drilling after completion of the bolting operation and an excavation for a side room near the Oro Fino Vein.

The underground mine is estimated to produce 500,000oz of gold equivalent over the next ten years.

Around 1,200 acres of mineral rights on War Eagle Mountain are under the company’s ownership, including the Diamond Creek Mill located at the foot of War Eagle Mountain.

The mill is connected through 6.2m of paved roads, enabling uninterrupted access to the Sinker Tunnel.
