Big Ridge Gold Corp. (TSX-V: BRAU) (OTCQB: ALVLF) is pleased to announce additional diamond drill results from its Phase I exploration drill program at the past-producing Hope Brook Gold Project, located in southwestern Newfoundland and Labrador. The drill holes reported in this press release are from drill holes that targeted the shallow southwestern extension of the Hope Brook Deposit.
Mike Bandrowski, President & CEO of Big Ridge, commented, “Drilling continues to intercept gold and copper mineralization outside the current resource envelope to the southwest, further supporting our thesis of continued mineralization to the southwest and potential resource expansion.”
Phase I Results
Results from the Phase I drill program continue to extend gold and copper mineralization to the southwest of the former producing Hope Brook open pit. The holes reported in the press release confirm near-surface mineralization in an untested gap in the current resource envelope, southwest of the resource envelope and also show the deposit remains open to the southwest.
Copper mineralization which was recovered by past mine operators as a by-product credit and is known to be associated with gold mineralization at Hope Brook, has not been included in the historic resource estimates. Big Ridge’s initial drill results have generated copper assays ranging from 0.05% Cu to 0.90% Cu in the majority of holes reported to date.

About Hope Brook
The Hope Brook Gold Project is an advanced stage, high-grade gold project that produced 752,162 ounces of gold from 1987 – 1997. Hope Brook hosts an indicated gold resource totalling 5,500,000 tonnes grading 4.77 grams per tonne gold for 844,000 ounces and inferred resources totalling 836,000 tonnes grading 4.11 grams per tonne gold for 110,000 ounces based on a 3.0 gram per tonne cut-off grade and a long-term gold price of US$1,200, according to a technical report for Big Ridge Gold Corp., prepared by authors Michael Cullen, P. Geo., and Matthew Harrington, P. Geo., of Mercator Geological Services Limited and Jeffrey Burke, P. Geo., and titled “NI 43-101 Technical Report for the Hope Brook Gold Project, Newfoundland And Labrador, Canada”, April 6, 2021.
The Hope Brook gold deposit is a high-sulfidation epithermal gold deposit hosted in the Proterozoic aged Whittle Hill Sandstone and is intruded by a Late Proterozoic quartz-feldspar porphyry sill-dike complex of the Roti Intrusive Suite. The deposit in located adjacent to and within an extensive advanced argillic alteration envelope which includes pyrophyllite, kaolinite, andalusite, and alunite. The principal gold mineralization occurs in a buff-colored massive, vuggy silicic alteration with an associated, less developed grey silicic alteration with pyrite, chalcopyrite and lesser bornite. Gold mineralization is also found with pyrite in units of advanced argillic alteration adjacent to or near silicic alteration horizons. The altered and mineralized zone is cut by mafic dykes whose contacts are often mineralized. All of the altered and mineralized sequences and the intruded dykes have been folded.
Hope Brook is located 85 kilometers east of Port aux Basques, Newfoundland. The project has well maintained infrastructure on site, including an operational 28-person camp, an 1,100-meter airstrip, an ice-free docking facility and importantly, connection to the provincial electrical power grid via an on-site substation.
Significant exploration potential remains on the 26,000-hectare concession providing a great opportunity to expand the mine area as well as surface showings throughout the concessions.

Quality Assurance and Quality Control
Big Ridge’s 2021-2022 drilling program, Quality Assurance/Quality Control and compilation of results employ a strict QA/QC program consistent with NI 43-101 and industry best practices. The Hope Brook project is supervised by Big Ridge’s Vice President Exploration, William McGuinty P. Geo.
Drill core is logged and split with half-core samples packaged and delivered to ALS Global’s geochemistry laboratory in Moncton, New Brunswick. Samples are dried and subsequently crushed to 70% passing a 2 mm mesh screen. A 250-gram split subsample is pulverized to a nominal 85% passing a 75-micron mesh screen. The remaining crushed sample (coarse reject) and pulverized sample (pulp reject) are retained for further analysis and quality control. All samples are analysed by Fire Assay with an Atomic Absorption (AA) finish using a 50 g aliquot of pulverized material. Samples are also analysed for copper using ICP AES with four-acid digestion. Big Ridge inserts third party reference control and blank samples in the sample stream to monitor assay performance and performs duplicate sampling of both pulp and reject material. 10% of samples submitted are part of the Company’s laboratory sample control protocols.
