Omineca Mining and Metals reports that it has completed testing of a grout plug meant to aid in accelerating a dewatering program of the existing mine workings at its underground alluvial gold project at Wingdam.
The pump down rate was found to be 85% faster after the grout plug was installed relative to before it was put into place.
The company plans to continue with a phased dewatering program involving the installation of an engineered plug system.
Once dewatered, the company will rehabilitate the underground workings in preparation to begin mining operations for a larger bulk sample based on the proof of concept bulk sample completed in 2012 that yielded 5.4 kilos or 174 ounces of placer gold.
The 2700-hectare Wingdam Project is located 45 kilometers east of Quesnel B.C. and 40 kilometers downstream from Barkerville in the Cariboo Mining District.
The property includes both placer and hard-rock tenures along the Lightning Creek valley.
Topographic conditions created a thick overburden which preserved a large portion of a placer-bearing channel from conventional surface placer mining activity.
Wingdam consists of a two and a half kilometer stretch of an underground, placer-bearing paleochannel buried by 40 meters of a wet mix of gravel and silt beneath Lightning Creek.
Lightning Creek was historically one of the more prolific placer streams during the Cariboo gold rush of the late 1800’s.
The grout plug system and the dewatering process together are an integral part of the company’s plan to safely extract the placer trapped beneath the wet overburden.
Any areas of the wet overburden that remain unstable after dewatering may be stabilized by ground freezing thereby enabling crosscuts across the underground channel.
Material from the cross cuts will be processed by trommel and wash plant with water, to extract the placer gold from the gravels, with the gravels then packed back into the crosscut.
The 2012 proof of concept bulk sample yielded 5.4 kilos or 174 ounces of raw placer gold from a two and a half meter wide crosscut that was 24 meters long across the gold bearing paleochannel.
The shares are trading at $0.055 on the TSX Venture Exchange under the symbol “OMM”.
