A number of personal and business circumstances, some timely and not so timely lead me to be involved in the Wingdam Project and ultimately, overseeing the successful completion of the bulk sample of what was a very rewarding project.

Historically the Wingdam deposit had, for the past 116 years defeated the miners, who had attempted to mine, using conventional underground mining methods, the alluvial gold deposit. The historic record indicated that the orebody was rich but due to sudden cave ins and the infamous “cariboo slum” the ore body remained virtually unmined. Infrastructure such as the “Deep Leed channel was constructed at considerable cost to facilitate gold recovery but the continuous and complete mining of the deposit had not been accomplished prior to CVG taking on the Project.

The sole purpose of the CVG project was to substantiate the grade of the gold bearing ore body. To facilitate this and knowing that conventional mining had not worked in the past CVG introduced and utilized ground freezing to stabilize the ground to be mined. Literature searches found no information that would suggest that this had been accomplished anywhere else in the world for an underground placer deposit.

The frozen ground would allow for the safe drifting and extraction of ore. If successful, the project could then be considered for full production.

The end result was that the freezing technique worked and the grade proved to be as rich as the historical data suggested.

In summary I respectfully acknowledge the contribution of Al Basham, Herb Robertson and Don Bernard to the acquisition and early success of the project. Also, my thanks to the miners, consultants and the many supplies that helped to complete a very rewarding and successful project.
