Sierra Grande Minerals Inc. provided an update on the mineral potential of the eastern B&C Springs Project. As part of its ongoing work, Sierra has acquired a database related to drilling undertaken on the northeastern part of its B&C Springs property, mainly during the 1970's and early 1980's. The drilling aimed to delineate a zone of molybdenum (Mo)-copper (Cu)-Silver (Ag) mineralization, which formed the basis for several reports and compilations written as recently as 2007. While the Company is not relying on these historical sources to calculate a NI43-101 compliant resource on the property, the data included in them have been compiled and analyzed by Sierra, and include partial assays for 43 vertical drill holes, many of which yielded intersections of significant grade and width.

Furthermore, the data indicate that 127 holes were drilled on the Property, and the results suggest that the modelled Mo-Cu mineralized zone encompasses an area roughly 2000 x 2300 m and that it remains open along strike. In September 2023, Sierra also located the B&C Springs drill core, and with permission from the storage facility owner, was able to gain access to perform an initial review of its condition. Notably, the Paradise Peak Mine 5.6 miles to the West/Southwest of the B&C Springs Project produced 1.6 million ounces of gold and 24 million ounces of silver from 1986 to 1994.

The B&C Springs property mirrors the potential of the Fairplay District in that it has both base (copper-silver-molybdenum) and precious (gold-silver) metals potential. Much of the focus for previous work at B&C Springs, including a considerable amount of drilling, was on the Mo-Cu-Ag mineralized zone on the east side of the property. However, farther west, in the Mildred Mine area, numerous historical prospecting pits, adits and shallow shafts exist, and the soil geochemical respon se for gold and silver in that area confirms that there is potential for precious metals mineralization.

Still farther west, across the area of the upper pediment blanketing some of the southern part of the property, the Company's expanded property holdings abut Almadex Minerals Ltd.'s Paradise Valley project, which has long been the focus for precious metals exploration. The historical work on either side of this pediment area hints at expanded potential for precious metals exploration, particularly beneath the shallow overburden of the upper part of the upper part of the pediment, and that potential was further reinforced by the results of both Sierra's recent drone-based aeromagnetic survey and its staking-related prospecting program, in which grab samples returned values up to 150.5 g/t gold.
