Show MAKE GOOD PROGRESS 1 OMR THE Geological Formation Ideal for Ore Deposition, According Ac-cording to Engineer. v Good progress is being made in driving driv-ing the main tunnel on the Baker Mining Min-ing company's property, located just east of the Maxfield mine in the Big Cottonwood district, according to the management. Mineralization is showing in the breast, and Frank Bover, general gen-eral manager of the propertv, is con lideut of cutting the main ore 'body that has been opened near the surface when the objective point of the tunnel is reached. The property embraces a part of the upper series of Ordovician limestones and lime'shales in which tho first iip1 cover of ore was made iu the Maxfield mine, according to Henry Jones, who recently completed an examination of the Baker holdings. The property also covers the lower and upper series of the Devonian limestones, lime shales and cream-colored rjuartzit.es. The northeastern portion ot the property embraces em-braces about 300 feet of the lower side of the Weber quartzites, known as the Ontario quartzites iu the Park City dis trie The same formation has been carefully care-fully traced several times through Kess-ler Kess-ler peak, through Montreal' hill, the Cardiff property, down the north slope I of Little Cottonwood, canyon, through the Old Columbus, now the property of j the Wasatch Mines company, southerly I through the ground of the South Hecla I company and continuing south on the east side of Peruvian gulch to Miller i hill and Mineral flat of American Fork canyon. The formation of the Baker ground is cut by dioritic porphyry, in some places appearing from one foot to several hun dred feet m width. This porphyritic rock is associated in some way with all of the known ore bodies in the Big and Little Cottonwood districts, and is believed be-lieved to be . the source of all the mineralization min-eralization and ore deposits as far south as the American Fork canyon. In the various mines along this mineral min-eral zone some of the ore has been' discovered dis-covered along the contact between the quartzite. and the limestone, known as contact deposits, other ore deposits have been found alone: the contact between the diorite and the limestone and other deposits are replacement deposits iu the limestone beds in conjunction with the mineralized fissures traveling through the northeast mineral-hearing fissures. All of these conditions exist and are possible of development on the Baker property. |
