The Technical Report, authored by Allan Armitage, Ph.D., P.Geo., and Ben Eggers, P.Geo., of SGS Geological Services ("SGS"), incorporates an updated Mineral Resource Estimate based on results from the Company's recently completed Phase I drill program in addition to 700 historic drill holes in the Company's database.

The Technical Report is available under the Company's profile at www.sedar.com and will also be available on the Company's website at www.bigridgegold.com.

As reported in the Company's press release dated February 21, 2023, and filed on SEDAR on that date, the Hope Brook Mineral Resource Estimate is comprised as follows:

• A Total Deposit Estimate of 1.2 Million Ounces grading 2.32 g/t Au in Indicated and 231,000 Ounces grading 3.24 g/t Au in Inferred categories.
• Open Pit Mineral Resource Estimate of 1.0 Million Ounces grading 2.14 g/t Au in the Indicated category

The report, titled "Technical Report on the Mineral Resource Estimate Update for the Hope Brook Gold Project, Newfoundland and Labrador, Canada" is dated April 6, 2023, and has an Effective date of January 17, 2023. The report was prepared in accordance with National Instrument 43-101 Standards for Disclosure for Mineral Projects.

Project Planning in 2023

With the Company's improved knowledge of the Hope Brook gold deposit, an updated resource estimate in hand and a significant number of underexplored gold targets on the Company's extensive landholding in southern Newfoundland and Labrador, the following projects are being considered:

• Continued drill testing for expansion of the deposit in the 240 Zone area.

• Processing optimization studies using materials from the company's library of 198 drill holes and sample reject material at site

  • Metallurgical testing to advance gold and copper recoveries.

  • Ore separation testing with the objective of removing unmineralized lithologies from key mineralized material.

• Field evaluation and detailed exploration of several priority targets including Northeast Extension, Old Man's Pond, Woodman's Droke, Phillips Brook and Cross Gulch, by surface mapping and sampling, induced polarization surveys and results-based follow-up drilling.

• Preliminary exploration of the lithium potential along 30 km of the Bay d'Est fault structure along the northern boundary of the Hope Brook Project.

Dr. Allan Armitage, P. Geo., and William McGuinty, P. Geo., Vice President Exploration for Big Ridge, each a Qualified Person within the meaning of NI 43-101, Standards of Disclosure for Mineral Projects, have reviewed and approved the technical information contained in this news release.

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. Initial production consisted of an open pit before moving to underground mining. Hope Brook operated using both heap leach (1987 - 1990) and conventional cyanidation milling methods (1989 - 1997) with a later inclusion of flotation concentration to recover copper (1991). Government records indicate that gold recoveries from milling ranged to low of 78.8% in 1987 to a high of 85.9% in 1989. Government and company annual reports indicate that gold recoveries ranged between a low of 82.1% in 1994 and a high of 89.9% in 1996 following a change of ownership. Copper flotation produced s concentrate at approximately 22% Cu and 34.3 g/t Au for shipment in 1992.

Hope Brook hosts an indicated gold resource totalling 16,190,000 tonnes grading 2.32 grams per tonne gold for 1.2 million ounces and inferred resources totalling 2,215,000 tonnes grading 3.25 grams per tonne gold for 231,000 ounces based on a 0.4 and 2.0 gram per tonne cut-off grade for open pit and underground resources respectively using and a long-term gold price of US$1,750.

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 is 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 accessory minerals. 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.
