Oregon Gold Mine

The potential output of the Grandview mine is truly astounding.

​

Various studies commissioned by Midwest Mining and Sigma Technology over the course of many years have concluded that Grandview Mine has the potential to be a HIGHLY profitable precious metal mining operation. All permits are in place with recovery problems resolved and both reclamation and exploration completed.

In February of 1995 by Charles Ross, Professional Geologist, estimated 482,143 tons X 0.5 opt = 241,171 contained ounces of gold. A 90 percent recovery rate could be attained, according to Mr. Ross by fine-tuning the milling operations. Based upon the current price of gold (1200 / ounce mined with a 90% recovery rate) and estimated costs of slope mining (mining cost per ounce of $85, process cost per ounce mined of $40), the potential gross profit is $1,075/oz mined, or approximately $259,258,825.

In another geological survey performed by John J. Oberling in December, 1995, random samples evidenced gold values to vary from .1 oz to over 70 oz. per ton. Mr. Oberling stated in his report that this estimate is “conservative and probably will average higher.” The veins were traced 1500 feet along the surface and vertically over 1200 feet with the width of the veins averaging mineralization of 1.5 feet. Using this information, Mr. Oberling’s report estimated underground reserves at 652,000 tons. During mining, “it is assumed that other veins will be encountered . . .that will add to the tonnage.” Approximately 80,000 tons of open pit ore is also available on the top of the No.1 Tunnel outcrop and in the vicinity of the No. 3 Adit. At an average of 0.50 oz. gold per ton, this would result in 366,000 ounces of gold. Using the estimate of $1200 per oz., the reserves would bring in gross revenue of approximately $440 million.
