The Providence Group of Mines is located in the Summerville Mining District, Tuolumne County, California, upon the eastern belt of the “Mother Lode” District. Within this belt are a number of the well-known, rich producing mines of California, including the Black Oak Mine, the Soulsby Mine, the Dead Horse Mine, the New Albany Mine, the Star King Mine and others from which many millions of ounces in gold have been taken. In the “Mother Lode” district, the general reports are that the mineralization increases in value with depth. These mines are located via passable all weather roads three miles east of the town of Tuolumne about 12 miles east of Sonora, California.
Mineralization: The veins of the Providence Mines are in black slates, lying parallel with each other at an angle of about 45 degrees, dipping toward the east. The strike of the veins is from south east to north-west. The formation contains intermediate porphyry dykes and limestone. The mineralized bodies are often found along these contacts. The mineralization bodies forms high grade shoots or lenses at varying distances along the veins. These lenses or shoots of mineralization have been opened up on various levels of the mine and a large amount of ore extracted.
Development: A double compartment shaft was sunk to a depth of 1470 ft. along the dip of the vein. Twelve drifts were run north and south of the shaft on twelve different levels. The number 12 level being about 1400 feet from the mouth of the shaft. From different levels, crosscuts were run east or west to develop and exploit parallel mineralized shoots found in parallel veins.
Some of these mineralized shoots and veins have been stoped out. In others the mineralization is still reported to remain in place. Good potential remains unknown at depth and along strike
The Providence Group of Gold Mines has not only been a great producer of gold in its historical past, further potential remains for similar but yet to be exploited gold resources.
The Providence Group of Mines has been historically identified and described as having similarities to many of the great mines within the “Mother Lode” gold district. The Providence Mines are known to have mined ore shoots with reported production of 30,000 to 50,000 ounces of gold within individual stopes with grades reported to average greater than 1.0 oz. / ton.
At that time, over 100 years ago, the lower levels of the mines were allowed to fill with water, which remain flooded to this day, and the lower eight levels were never reopened. Thus, conditions of the workings in these lower levels are in the same condition that they were in when the operations ceased in 1907, at which time the former manager was reported to be milling profitable high grade ore from the tenth and eleventh levels. At the same time development work had been completed on the twelfth level into good bodies of mineralization.
The Providence Group of Mines is an extremely intriguing proven gold property with an impressive historical past production of significant high grade gold. It remains a current mystery as to how it has been forgotten. The Providence Group of Gold Mines is in an impressive Mother lode setting and is truly a unique opportunity until now frozen in the passage of time.
