Toronto, Ontario--(Newsfile Corp. - October 22, 2024) - Big Ridge Gold Corp. (TSXV: BRAU) (OTCQB: ALVLF) ("Big Ridge" or the "Company") is pleased to provide an update of activities at the Company's Hope Brook Gold Project ("HBGP") located in Southern Newfoundland.
Michael Bandrowski, President & CEO of the Company, commented: "We are excited to continue our systematic exploration program along a series on highly prospective gold bearing structures to the southwest of the Main and 240 Zones at the Hope Brook Gold Project. The ongoing field work covers areas defined during our 2023 exploration program (see Press Release dated April 18, 2024). This is a critical step for the growth of the HBGP as the company looks to define robust drill targets that we plan to have drill ready for 2025."
Geophysical Interpretation at Hope Brook
The 2023 surveys included walking magnetometer surveys completed over all lines on both the Hope Brook and the Old Man's Pond grids. Time domain DC Induced Polarization ("DCIP") surveying was completed over only prioritized areas of the Hope Brook (29.1 km) and Old Man's Pond (9.0 km) grids due to seasonal time constraints. Survey QA/QC and data interpretation were completed by Ronacher McKenzie Geosciences Inc. ("RMG")
Historic Titan 24 Magnetotelluric (MT) and induced polarization data over the Hope Brook deposit show parallel high chargeability anomalies with strong correlations to the locations of the Hope Brook Main Deposit and the 240 Zone, located 300 m to the southwest, both contained within the footprint of the 2023 Hope Brook Mineral Resource Estimate dated April 6, 2023 (see Figure 1).
The 2023 survey extended gridding for 4 km to the southwest and included coverage of the 240 Zone and the full thickness of the Hope Brook Deformation Zone lithologies.
Geophysical interpretation by RMG suggests the 240 Zone geophysical signature is a spatially distinct stratigraphic horizon from the similarly anomalous trend on the northern limit of the Hope Brook Deformation Zone which hosts the Hope Brook Mine. The 240 Zone appears to coincide with the downward projection of the southern chargeability feature in this recent survey, along the southern limit of the Hope Brook Deformation Zone. There is also distinct break within the IP anomaly's trend at this point, suggesting late offset. This southern chargeability trend is present continuously over approximately 3 km of the 2023 surveyed grid.
The northern chargeability anomaly extends southwest from the Hope Brook Mine, 1.5 km to the Chetwynd Copper zone located along the Cinq Cerfs Fault. The Chetwynd Copper Zone was explored in the 1930's for copper mineralization. Historic drilling and surface geology have detected gold hosted in high sulphidation, argillic altered lithologies parallel to the Cinq Cerfs Fault. Resistivity and chargeability anomalies in this area appear to follow the heavily altered rocks extending between the Hope Brook Mine and the Chetwynd showing, these have also been offset locally by late faulting.
Additional study of the geophysical results suggests that stratigraphic horizons with anomalous chargeability are part of a folded sequence (see Figure 2), as seen in the Hope Brook mine area. The inferred folds are isoclinal, likely dipping steeply to the southeast with shallow axes trending to the southwest. Recognizing these folds will be an important factor in tracking alteration and mineralization southwesterly and at depth.
Field Reconnaissance Work
During July and August 2024 ground exploration continued at the HBGP, targeting the Chetwynd Prospect area and the mineralized lithologies contained in the Hope Brook Deformation Zone. This work is a continuation of the 2023 field season during which the Hope Brook land package, outside of the Hope Brook Mine, was evaluated. The Chetwynd Prospect area is a high priority for the company.
The general characteristics of the prospect are:
- On strike to Hope Brook Mine, approximately 2 km southwest
- Within the Hope Brook Deformation Zone and described as containing lenses of highly strained silicic rocks and advanced argillic alteration
- Comprises both buff (first) and grey (second) stages of gold-bearing silicic alteration
- Locally contains strongly anomalous Cu, As, Hg values and up to 2.8 g/t Au (Copper Shaft)
- 2023 IP data illustrates the need for deeper drilling and possible further IP and trenching
Prospecting in previously unsampled rocks and re-sampling of known mineralization was carried out with 36 grab samples being submitted for analysis in August. Of the 36 grabs assayed, 8 reported between 100 ppb Au and 2,300 ppb Au with the remainder of the samples reporting traces of gold.
Channel sampling was carried out on largely unsampled historical trenches to the northeast of Chetwynd and to the west and southwest of the Hope Brook Mine. This work comprised 51 channel samples. A further 114 samples were taken in historical, previously unsampled core, from holes in the Chetwynd Prospect area and along the Cinq Cerf Fault Area. Gold assay and ICP analysis for these samples are pending. Exploration work continued in the Hope Brook Deformation Zone in October.
Preparation for 2025 Drill Program
During 2024 field operations, Big Ridge staff will follow-up on the results and interpretations developed from the 2023 DC Induced Polarization, magnetometer, and reconnaissance sampling surveys, with a focus on a 5 km section of the Cinq Cerfs Deformation Zone, extending from the 240 Zone to the southwest. This stratigraphy contains variably argillic altered metavolcanic rocks and several prominent chargeability anomalies in strike continuation from the Hope Brook deposit. The work will assist with placement of drill holes for a new campaign in 2025. The team will also investigate a suite of anomalous gold-in-rock results, located south of the Cinq Cerfs Deformation Zone identified in 2023.
Quality Assurance and Quality Control (QA/QC)
Quality Assurance/Quality Control and compilation of results employ a strict QA/QC program consistent with NI 43-101 and industry best practices. Historical drill core was split with half-core samples packaged and delivered to SGS Canada's prep Laboratory in Grand Falls Windsor, Newfoundland, by Big Ridge staff.
All samples are analysed by Fire Assay with an Atomic Absorption (AA) finish using a 50 g aliquot of pulverized material. Big Ridge inserts third party reference control and blank samples in the sample stream to monitor assay performance. 10% of samples submitted are part of the Company's laboratory sample control protocols.

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 between a low of 78.8% in 1987 and 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 89.83% in 1996 following a change of ownership. Copper flotation produced a 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 grades for open pit and underground resources respectively using a long-term gold price of US$1,750.
Hope Brook is located 85 kilometres 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 approximately 5,900-hectare Project area, providing a great opportunity to expand the mine resource area as well as continued evaluation of surface showings throughout the licences.
