Mountain Boy Minerals Ltd (TSX-V:MTB, OTCQB:MBYMF) has announced that the fieldwork is underway to expand the copper mineralized zones discovered last year on the Telegraph Copper-Gold Project in British Columbia's Golden Triangle.

The company said this work is directed at the Border Zone, an area that saw limited previous exploration as it straddled a property line before Mountain Boy consolidated the property last year. The Border Zone sits in the middle of a 6 kilometre (km) trend with evidence of porphyry-style mineralization previously identified to the north and south.

In a statement, Lawrence Roulston, Mountain Boy's chief executive officer, said: "Ongoing field work continues to validate the presence of at least one center of porphyry-style mineralization. The presence of visibly high-grade copper mineralization associated with veins and hydrothermal breccias is indicative of proximity to a porphyry system and may well constitute a target in its own right."

During the 2021 field season, numerous outcrop and talus samples grading more than 0.5% copper (up to 17.9%) were discovered 3.7 km southeast of the historic drilling at Dok in an area now known as Nirvana Bowl. Work this season has discovered a series of epithermal-style veins up to 750 metres (m) west of Nirvana Bowl.

The veins are interpreted to be related to an underlying porphyry system. Two main styles of vein mineralization are observed, including quartz-carbonate hydrothermal breccia veins  and quartz-malachite>sulfide veins. The veins are hosted in a porphyritic to aphanitic andesite. Detailed photos of some of the representative styles of mineralization include sample of massive sulphide, dominantly pyrite; massive pyrite with covellite; and massive malachite>azurite>chrysocolla in a vuggy quartz vein.

Numerous felsic to intermediate intrusive rocks have been mapped in the vicinity of both styles of mineralized veins. Compositions range from rhyolitic to andesitic, including many porphyritic dykes. The majority of the dykes strike north-south, subparallel to hydrothermal breccia veins. Hydrothermal breccia crosscuts and contains clasts of recognizable dyke material. Dykes are variably altered, exhibiting both potassic and argillic alteration.

Other targets on the property

Mountain Boy said several other targets are also being further explored, including the Strata Mountain Zone. A 4.5 square km area of gossanous weathering 4 km east of the Dok target is currently being prospected and sampled with a view to assessing potential for porphyry style mineralization.

Field observations to-date show that the area is occupied by a dense swarm of potassic altered dykes separated by very distinctive orange corridors of quartz-sericite-pyrite alteration of between 1m and 50m width. Within these corridors, zones of very strong gossan can be seen. In deeper incised areas the gossans are seen to be the result of intense supergene oxidation of up to 20% sulphide (including pyrite). Field observations indicate that the intrusive and hydrothermal activity occurred during the Early Jurassic geological period, associated with the bulk of the porphyry systems in the Golden Triangle.

The area has the visual characteristics and scale of a porphyry system, including the dyke swarm and the large areas of iron oxides after sulphides (now largely supergene oxidized). Work is underway to determine if this mineralized area is part of the same system as the Dok trend or is a distinct mineralizing system.

Stock option grant

The company also announced the grant of stock options to its employees and consultants for an aggregate of 600,000 shares at an exercise price of $0.17 for a term of 5 years, expiring on July 12, 2027.

Mountain Boy has six active projects spanning 624 square kilometres (62,464 hectares) in the prolific Golden Triangle of northern British Columbia.

The 252 square kilometre Telegraph Project is located in the vicinity of several large porphyry deposits including Galore Creek (Teck - Newmont), Schaft Creek (Teck - Copper Fox), Big Red (Libero Copper and Gold), Saddle and Saddle North (Newmont) and the operating Red Chris copper-gold mine (Newcrest - Imperial Metals).
