Sierra Grande Outlines Substantial Molybdenum Copper Silver Goal at Jap B&C Springs Challenge, Western Nevada Specific Occasions

Must read


Surrey, British Columbia, Nov. 15, 2023 (GLOBE NEWSWIRE) — Sierra Grande Minerals Inc. (the “Firm” or “Sierra”) (CSE: SGRO) (OTCQB: SIERF) (FSE: SRR) (“Sierra” or the “Firm”) is happy to offer an replace on the mineral potential of the jap B&C Springs Challenge.

As a part of its ongoing work, Sierra has acquired a database associated to drilling undertaken on the northeastern a part of its B&C Springs property, primarily through the 1970’s and early 1980’s. The drilling aimed to delineate a zone of molybdenum (Mo)-copper (Cu)-Silver (Ag) mineralization, which fashioned the premise for a number of experiences and compilations written as just lately as 2007. Whereas the Firm will not be counting on these historic sources to recalculate a NI43-101 compliant useful resource on the property, the info included in them have been compiled and analyzed by Sierra, and embody partial assays for 43 vertical drill holes, a lot of which yielded intersections of great grade and width. Moreover, the info point out that 127 holes had been drilled on the Property, and the outcomes counsel that the modelled Mo-Cu mineralized zone encompasses an space roughly 2000 x 2300 m and that it stays open alongside strike (see Determine 1). In September 2023, Sierra additionally situated the B&C Springs drill core, and with permission from the storage facility proprietor, was in a position to achieve entry to carry out an preliminary overview of its situation. Sierra’s preliminary evaluation means that better than 80% of the core is undamaged and in glorious situation, in cardboard core containers that had been stacked on pallets and shrink-wrapped in plastic. Sierra estimates there are better than 40 pallets containing between 75 and 100 containers of core per pallet (See Photographs 1 to 4). Sierra’s subsequent steps are to have a geologist carry out a extra full overview of the core to evaluate its geological worth within the context of the B&C Springs venture.

The Upside

In 2022, Sierra undertook a soil geochemical survey throughout the B&C Springs Property aimed toward evaluating the dear metals potential. From that work, a northwesterly trending copper-in-soil geochemical anomaly, partly coincident with Mo and Ag, was outlined. This anomaly extends past the traditionally drilled space in each instructions (see Picture 2) and stays open. The traditionally drilled space has a comparatively muted geochemical response (see Picture 2), largely as a result of the mineralized zone is capped by a weakly mineralized greenstone or diorite physique (see Picture 1).

The Firm additionally accomplished reconnaissance geological work that means the multi-element soil geochemical anomaly is co-spatial with variably veined and chalcopyrite-mineralized granitic dikes that additionally development northwesterly. Though the dikes are usually not proven on regional geologic maps of the Property, geologic maps instantly to the west (Vitaliano and Callaghan 1963, see Determine 2) present an in depth and laterally steady porphyritic dike swarm which tendencies southeasterly towards the traditionally drilled B&C Springs Mo-Cu-Ag zone.

This implies that the porphyritic dikes and the mineralization at B&C Springs are associated, and that additional exploration potential exists alongside this development. This affiliation is strengthened by the Firm’s just lately accomplished drone-based magnetometer survey (see information dated March 27th, 2023) which outlines many linear magnetic options on the Property with tendencies mirroring the porphyritic dikes and the geochemical anomalies.

Deliberate Work

The Firm is taking steps to plan additional exploration for the Mo-Cu-Ag potential on the property.  The plans embody:

  • Detailed mapping of the world of historic drilling, and past alongside the development of anomalous soil geochemistry, with a watch to delineating the presence of porphyry dikes and to investigating their relationship to the mineralization and to the prevailing soil geochemical anomalies
  • Detailed overview of B&C Springs historic drill core
  • Surveying and relocating historic drill collars
  • Infilling and lengthening the soil geochemical pattern grid to higher outline and perceive the distribution of mineralization
  • Provoke drill allowing of quite a few affirmation holes inside the space of earlier drilling

Sierra’s CEO Sonny Janda commented, “The acquisition of the historic B&C Springs dataset in context with Sierra’s latest exploration work highlights the potential for the invention of a big base metals deposit on the jap portion of the B&C Springs Property. We look ahead to getting the staff within the subject quickly to observe up on these thrilling developments.”

Director Appointment

The Firm welcomes Ben Kramer-Miller to the board of administrators. Ben Kramer-Miller has over 5 years of expertise in mineral exploration in Nevada. He has labored with a number of publicly traded junior explorers together with West Vault Mining, Angold Sources, and NV Gold, specializing in company technique and investor relations. He’s a co-founder and former supervisor of Grandview Exploration, LLC:a non-public venture generator with a deal with gold prospects in Nevada and Arizona.

In regards to the B&C Springs Property

The B&C Springs property is situated within the southern Paradise Vary in west-central Nevada, inside the Fairplay Mining District, which is thought primarily for its treasured metals potential, however which additionally hosts quite a few copper deposits and occurrences. Notably, the Paradise Peak Mine 5.6 miles to the West/Southwest of the B&C Springs Challenge 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 each base (copper-silver-molybdenum) and treasured (gold-silver) metals potential. A lot of the main target for earlier work at B&C Springs, together with a substantial quantity of drilling, was on the Mo-Cu-Ag mineralized zone on the east aspect of the property. Nevertheless, farther west, within the Mildred Mine space, quite a few historic prospecting pits, adits and shallow shafts exist, and the soil geochemical response for gold and silver in that space confirms that there’s potential for treasured metals mineralization. Nonetheless farther west, throughout the world of the higher pediment blanketing among the southern a part of the property, the Firm’s expanded property holdings abut Almadex Minerals Ltd.’s Paradise Valley venture, which has lengthy been the main target for treasured metals exploration (see Determine 1). The historic work on both aspect of this pediment space hints at expanded potential for treasured metals exploration, significantly beneath the shallow overburden of the higher a part of the pediment, and that potential was additional strengthened by the outcomes of each Sierra’s latest drone-based aeromagnetic survey and its staking-related prospecting program, during which seize samples returned values as much as 150.5 g/t gold (see above and Picture 1).
