Cartier Resources Inc. (″ Cartier ″ or the ″ Company ″) (TSXV: ECR,OTC:ECRFF; FSE: 6CA) is pleased to announce it has awarded the contract for beginning the first environmental baseline studies for the Cadillac project and an initial evaluation of economic assessment of the past-producing Chimo mine tailings to Stantec, a global leader in sustainable design and engineering. The baseline studies will be divided into two distinct parts which include 1) environmental baseline desktop study and 2) preliminary environmental geochemical characterization.

‘ These initial baseline studies will form a foundation for Cartier by providing a comprehensive understanding of the current environmental conditions and identifying potential impacts of future development planning of the Cadillac project. The results will help guide our advancing strategies in a responsible and sustainable manner, enabling the design and implementing operations that minimize environmental impact while optimizing the economic potential of the project . ‘ – Philippe Cloutier, President and CEO of Cartier.

‘ We continue to advance the Cadillac project with a dual-focus strategy: drilling an ambitious 100,000-meter drilling campaign that combines the extensions of known gold zones and the exploration of new high-priority targets, identified using cutting-edge AI technology through our collaboration with VRIFY and now launching of the foundational environmental baseline studies. These efforts will be conducted simultaneously, with the potential for additional work emerging as the project advances. ‘ – Ronan Deroff, Vice President Exploration of Cartier.

Below is the description of the different parts:

Part 1 – Environmental Baseline Desktop Study

The environmental desktop study aims to document and characterize the potential environmental constraints on the Cadillac project footprint. This approach identifies potential environmental issues, such as atmospheric conditions, surface and groundwater management, wetlands and natural environments, terrestrial, avian and aquatic fauna as well as land uses.

The approach consists of a rigorous document review that will allow for planning the future general development of the Cadillac project, identifying sensitive areas and minimizing environmental impacts. This first step will permit to plan a comprehensive field work as a next step to the environmental baseline studies. All the information will be sufficiently comprehensive to serve as a basis for drafting Chapter 20 of a possible update to the Preliminary Economic Assessment (PEA).

Part 2 – Preliminary Environmental Geochemical Characterization

The preliminary environmental geochemical characterization study aims to assess the potential geochemical risks of the waste rock and ore that will be extracted from the operations, as well as the tailings generated during ore processing.

In accordance with the criteria of the Guide de caractérisation des résidus miniers et du minerai (GCRMM), geochemical characterization is used to classify mining materials in terms of their acid generation and metal leaching potential. Static tests will be conducted on approximately fifty samples representative of the various lithologies present on the site to determine appropriate management methods for these materials, in accordance with the guidelines of Directive 019 of the Ministère de l’Environnement, de la Lutte contre les changements climatiques, de la Faune et des Parcs (MELCCFP).

Part 3 – Assessment of the economic assessment of the past-producing Chimo mine tailings

This assessment aims to determine whether economic recovery of the Chimo mine tailings is feasible, considering its geochemical, granulometric and metallurgical characteristics.

The study will consist of systematic sampling, with approximately fifty sample sites planned to cover the entire tailings facility. All required authorizations to perform the sampling will be obtained prior to the field work.

S eptember 9, 2025 TheNewswire – Vancouver, British Columbia Blue Lagoon Resources Inc. (‘Blue Lagoon’ or the ‘Company’) (CSE: BLLG,OTC:BLAGF; OTCQB: BLAGF; FSE: 7BL) is pleased to provide an update on its Dome Mountain Gold Project, where the Company is nearing final commissioning of its Moving Bed Biofilm Reactor (MBBR) water treatment system – the final step required before commencing blasting.

The Company expects the MBBR to be fully activated within the next 7 to 10 days , at which point the water treatment plant will be fully commissioned and blasting can begin. In the meantime, underground preparation work is scheduled to start this week to ensure the operation is fully ready for the start of mining.

Underground Work To Commence This Week

Work beginning this week includes:

• Establishing emergency egress exit points – ensuring all ladders are secure and viable.

• Bolt testing – testing approximately 10% of bolting as per the Ground Control Management Plan.

• Re-establishing the ventilation system – moving and wiring underground fans and ventilation ducts.

• Clearing and fortifying underground magazine storage units and purchasing explosives.

• Moving small waste piles to improve efficiency once blasting begins.

• Cleaning the underground sump.

• Drilling at the rollover to establish the first exposed ore face.

Once the MBBR system is commissioned (expected in the next 7 to 10 days), drilling and blasting will begin immediately at both the rollover and in the incline (development work).

‘We are now extremely close to begin mining,’ said Rana Vig, President & CEO of Blue Lagoon Resources. ‘The MBBR commissioning at Dome Mountain is the last remaining step before blasting can commence, and our crews are already underground preparing for operations. We expect to transition quickly into production and near-term cash flow once the system is online.’

To further strengthen its operational readiness, Blue Lagoon has added two experienced professionals to its team:

Michael Kendall – Underground Mine Supervisor

Mr. Kendall brings more than three decades of hands-on underground mining experience, with a proven track record of leading safe, efficient, and high-performing crews across some of Canada’s most notable operations, including Eskay Creek, Rice Lake, Myra Falls, Red Chris, and Minto.

• Former Underground Mine Manager at Fortis Mining and Underground Supervisor at Barminco (Red Chris).

• Extensive experience in mine planning, development, and production management, including recommissioning and optimization of underground operations.

• Recognized Mine Rescue Captain, with multiple provincial championships and decades of safety leadership.

Mr. Kendall’s deep operational knowledge and safety-first approach will be instrumental as Dome Mountain transitions from development into steady-state production.

Dr. Francis Salifu – Environmental Manager

The Company has also appointed an Environmental Manager, a seasoned professional with over 15 years of progressive experience in mining-sector environmental management, including more than five years in senior supervisory roles.

• PhD in Environmental Science.

• Expertise in ML/ARD mitigation, water quality and water balance modeling, and biochemical reactor (BCR) systems.

• Formerly with Conuma Resources, PwC, and the Alberta Energy Regulator, where they developed integrated environmental management programs and improved site compliance by more than 60%.

• Skilled in stakeholder engagement with regulators, consultants, and Indigenous communities, with a strong focus on sustainability and continuous improvement.

This appointment underscores Blue Lagoon’s commitment to the highest standards of environmental compliance and responsible mining as production begins.

‘As we prepare for mining and near-term cash flow, building the right team is critical,’ said Rana Vig, President & CEO of Blue Lagoon Resources. ‘Michael’s extensive underground experience and Francis’s proven leadership in sustainability both strengthen our operational readiness. These hires reinforce our commitment to safety, environmental stewardship, and efficient execution at Dome Mountain

About Blue Lagoon Resources Inc.

VANCOUVER, BC TheNewswire – September 9, 2025 Heritage Mining Ltd. (CSE: HML FRA: Y66) (‘ Heritage ‘ or the ‘ Company ‘) is pleased to announce a confirmed broad gold zone within a newly discovered ~74m wide quartz vein system (true width unknown) associated with a magnetic anomaly that extends for ~4km along strike length and up to 200m in width (Figure 1, 2) at its flagship Drayton Black Lake Project. Scout drilling targeted this previously unrecognized magnetic feature at Zone Three Extension, as part of the ongoing 2025 Exploration Scout Drill Program.

DBL Exploration Update Highlights

Drilling at Drayton-Black Lake (‘ DBL ‘) Zone 3 Extension prospect confirms gold mineralization over broad widths and associated with a thick quartz vein structure that is up to 74m in core length (true width unknown) as initially reported in Heritage’s press release dated May 15, 2025 and July 22, 2025.

Drill Hole HML25-013 intersected

• 0.98 g/t Au over 5.00m from 101.00m (Figure 3)

• 1.11 g/t Au over 11.09m from 115.91m

Including: 4g/t Au over 2m from 125m (Figure 3)

‘We are very pleased with the discovery of such a wide quartz vein structure. Our limited drilling has now confirmed a broad zone of gold mineralization associated with the ‘mega-quartz vein structure’.  The Company is excited by the potential this vein system exhibits, and we look forward to further communicating the next steps as well as findings on our other projects to the market in short order.’ Commented Peter Schloo, President, CEO and Director of Heritage Mining Ltd.

‘The intersection of very wide (~74m wide in core length, HML25-013) strongly deformed quartz vein in drill holes from Zone 3 Extension in the Lake of Bays Batholith was a great proof of concept for our geology/mineralization model. Multiple stages of deformation, fluid ingress, alteration, and sulphide deposition are evident within the quartz vein system. The return of assays showing a composite interval of 0.98 g/t Au over 5.00m and 1.11 g/t Au over 11.09m (including 4g/t Au over 2m from 125m) in hole HML25-013 provides further encouragement for discovery and support of our model.’ Commented Brett Davis, Structural Geologist Consultant to Heritage Mining Ltd.

Discussion of Results

DBL – Zone 3 Extension

The 2025 scout drill program at Zone 3 Extension targeted granite-hosted mineralised quartz-vein structures that were first discovered in the HML Zone 3 drilling program of August 2024 (Figure 2).  The recently completed drill program comprised 4 holes for a total 1105.5m.  Drilling targeted a northeast-southwest trending magnetic lineament, which appears to control the quartz veining.  Drilling is considered a technical success with two ( HML25-011 and 013 ) of the four holes intersecting a well-developed quartz vein structure, including drill hole HML25-013 that intersected a 74m wide vein structure (true width unknown).  Assays received for HML25-010, 011, 012, 13, 14.

Assay results from HML 25-013 confirm broad gold mineralization. Based on the Drone Magnetic survey, the ‘mega-quartz vein structure’ has a potential strike length of ~4km and warrants additional exploration drilling.

Internal dilution is no more then 0.20 g/t Au over a 5m interval.

Figure 4: HML25-013 Box 24 (103.29m – 107.68m) 1.83 g/t Au from 103.5m

Assay results from HML 25-014 confirm anomalous gold values outside the quartz vein zone and inside the granite batholith providing support of a potential mineralized vein system.

HML25-014 Highlights:

• • • • 0.87 g/t Au over 0.46m from 310.82m

      • 0.63 g/t Au over 0.52m from 315.75m

Assays for HML25-010 & 011 & 14 confirm locally elevated gold values in the vein structure per press released July 22, 2025 with HML25-014 missing the structure due to dip direction.

Conclusion

The Company believes additional drilling is warranted to test along this major quartz vein structure along strike.   The Company has proposed an additional 10 holes to test along a 2km strike length of the magnetic lineament (Figure 3) the complete program proposal for the remainder of 2025 will be communicated in short order.

Qualified Person

Stephen Hughes P. Geo, Strategic Advisor for the Company, serves as a qualified person as defined by National Instrument 43-101 – Standards of Disclosure for Mineral Projects and has reviewed the scientific and technical information in this news release, approving the disclosure herein.

Technical Program

Heritage Mining adheres to a strict QA/QC protocol for handling, sampling, sample transportation and analyses.  Chain-of-custody protocols are designed to ensure security of samples until their delivery at the laboratory.

Sampling, Sub-sampling, and Laboratory Analysis for Heritage Mining Drayton Black Lake Project All drilling at the Drayton Black Lake project recovers NQ core. Drill core is systematically split in half using a diamond saw. A qualified geologist examines the drill core, marking intervals for sampling and indicating the cutting line. Sample lengths are typically 1.0 metre, adjusted to a minimum length of 0.5 metre as necessary to respect lithological and/or mineralogical contacts and to isolate narrow veins or structures that may contain higher-grade mineralization.

Technicians saw the core along the cutting lines determined by the geologist. One half of the core is retained as a witness sample, while the other half is submitted for analysis. Individual sample bags are securely sealed and placed into sealed bags, which are then clearly marked with their contents.

Heritage Mining submits samples for gold determination by PhotonAssay to ALS Canada Ltd. (‘ ALS ‘). ALS operates under a commercial contract with Heritage Mining.

Drill core samples are shipped to ALS for sample preparation at their facilities in Thunderbay Ontario. ALS is an ISO/IEC 17025:2017 accredited laboratory for the PhotonAssay method in addition to a variety of diverse metal determination methods.

Analytical Procedures

The ALS procedure for PhotonAssay involves lab applying preparation codes LOG-21 (sample logging via barcode), CRU-31 (fine crushing so that 70% passes through a 2mm screen) and SPL-32a (rotary splitting of a representative ~500g subsample)  followed by analytical code Au-PA01 which is a non-destructive gold analysis method using high-energy X-rays with a gold detection range from 0.03 ppm to 350ppm.

After gold assays are returned, Heritage then may choose to perform multi-element assays on selected samples based on the gold results. In these cases, sample preparation codes FND-05 (locate and use remaining crushed material from Au-PA01) and PUL-32m (pulverization so that >85% passes 75 µm screen) are then applied followed by analytical code ME-MS61 (multi-element ICP-MS analysis for base metals, pathfinder elements, lithophile elements and rare earth elements).
