Big Ridge Announces First Results from Hope Brook Phase I Drill Program Intersects 5.84 g/t Au Across 14.8 M at Shallow Depths
Toronto, April 5, 2022 - Big Ridge Gold Corp. (TSXV: BRAU) (OTCQB: ALVLF) ("Big Ridge") is pleased to announce initial diamond drill results from its 25,000-meter ("m"), Phase I drill program at the past-producing Hope Brook Gold Project, located in southwestern Newfoundland and Labrador. Big Ridge commenced the Phase I drilling in early November 2021 and completed 3,729 m in 17 holes before breaking for the holidays. The drill holes reported in this press release targeted the shallow southwestern extension of the Hope Brook Deposit.
Mike Bandrowski, President & CEO of Big Ridge, commented, "Today's drill results southwest and along strike of the Hope Brook open pit confirm near-surface mineralization remains open for potential resource growth, and the copper mineralization, that is being reported for the first time, illustrates the possibility of a by-product credit. The Phase I drill program is very exciting as 100% of our holes have intersected gold mineralization and two of those have intersected visible gold."
- Drill hole HB-21-152 intersected 5.84 g/t Au over 14.8 m including 19.9 g/t Au over 3.4 m, Drill hole HB-21-142 intersected 5.58 g/t Au over 6.1 m including 25.2 g/t Au over 0.5 m and Drill hole HB-21-138 intersected 1.98 g/t Au over 23.1 m including 5.30 g/t Au over 5.89 m.
- Phase I drilling recommenced in January 2022 and approximately 11,400 m in 43 holes have been completed as of this press release.
- Drilling continues to extend gold mineralization outside the current resource shell that is based on a gold price of US$1,200 per ounce and 3.0 g/t Au cut-off grade.
- 100% of the drill results received to date have intersected gold mineralization. The Phase 1 drill program is expected to run until August 2022 and will focus on connecting the Main Zone and 240 Zone near surface and at depth respectively and testing the down dip extensions to both the Main and 240 Zones before moving to test the NE Extension.
- Big Ridge will continue to highlight copper mineralization from the Phase I drill program at Hope Brook as past exploration programs have not quantified or reported on this potentially economic mineralization.
Phase I Results
The initial drilling in the Phase I drill program has successfully confirmed and extended gold mineralization to the southwest of the former producing Hope Brook open pit. Hole HB-21-152 intersected 19.9 g/t Au over 3.4 m within a wider interval of 14.8 m grading 5.84 g/t Au. This hole successfully intersected gold mineralization at a shallow depth of 52.2 m within the main target vuggy silica sulphide zone.
Copper, 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 0.79% Cu, suggesting that copper could be an important consideration and product in a future mining operation.

- Intervals are presented in core length; holes are generally planned to intersect mineralization as close to perpendicular to strike as possible; true widths are estimated to be 75% of downhole length when hole and mineralized horizons orientations are considered.
- Assay results presented are not capped. Intercepts occur within geological confines of major zones but have not been correlated to individual structures/horizons within these zones at this time.
- Vertical depth is measured from the surface to the mid-point of the reported interval.

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, 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 (QA/QC)
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.
