Swanson Project and Beacon Gold Mill Integration: PEA Update

Lafleur Minerals is progressing with the Preliminary Economic Assessment (PEA) for their Swanson project in Quebec, with the goal of bringing Swanson into production and restarting the Beacon Gold Mill within the next 12 months. The PEA is expected to be completed by the end of the current year.

PEA Scope and Key Activities

Consultants at ERM are overseeing various aspects of the PEA, including:

  • Mine Design: Developing pit shell designs for the Swanson deposit.
  • Integration with Beacon Gold Mill: A core focus is integrating the Swanson deposit with the 100% owned Beacon Gold Mill, located approximately 45-50 km south of Swanson. This integration is a departure from traditional separate project evaluations.
  • Ore Sorting Testing: Preliminary testing for ore sorting is being conducted by SRC in Saskatchewan.
  • Metallurgical Testing: Comprehensive metallurgical testing is underway using historical drill core and new drilling samples from Swanson. This aims to characterize the ore for processing at the Beacon Gold Mill.
  • Resource Update: A mineral resource update for the Swanson deposit is being conducted concurrently, involving twin holes and at least a dozen additional holes. The purpose is to verify historical drilling data and conduct infill drilling. Results are anticipated within the next few weeks.

Project Details and Assumptions

The PEA is examining the mining of the Swanson deposit, which is situated on an existing mining lease and is 100% owned by Lafleur. The mined ore will be trucked to the Beacon Gold Mill.

  • Beacon Gold Mill History: The mill was previously used by Monarch for their B-form mine. Lafleur aims to process ore from Swanson and potentially other nearby deposits.
  • Swanson's Advantage: Swanson is considered advanced and on an existing lease, allowing for quicker production compared to other regional deposits.
  • Metallurgical Integration: The PEA is integrating the detailed knowledge of the Beacon Gold Mill's flowsheets and ore processing capabilities with the Swanson deposit's characteristics. Testing is being performed to de-risk this integration.

Level of Detail and Costing

While termed a PEA, the study is described as being closer to a Pre-Feasibility Study (PFS) level due to the detailed nature of the work.

  • Cost Baseline: Lafleur is moving beyond generic benchmarking by utilizing 2022 Beacon operating data and reconciling it with current cost inflation.
  • Mill Restart Costs: Full assessments of the mill have been conducted, including the costs for restart and maintenance.
  • Trucking Costs: Engagements with contractors have provided firm cost estimates for trucking ore from Swanson to Beacon.
  • Historical Mine Plans: Previous open-pit mine plans for Swanson, developed by Nikko Eagle approximately 15 years ago, are being upgraded due to additional drilling that suggests a larger pit.
  • Certainty of Estimates: The company is aiming for higher certainty than typical PEA Class 5 estimates. For example, ore sorting studies are incorporating both historical and recent drilling data. Metallurgical testing is being conducted by SGS on samples from the deposit's center, providing tangible data rather than relying on older studies.
  • Mill Team: A dedicated team of process engineers, metallurgists, and other specialists is already working on the mill restart plan.
  • Existing Stockpile: A 5,000-ton stockpile from a previous deposit at Beacon is available for test material to get the mill running.
  • Reduced Error Rates: Due to extensive prior work and an existing mill that operated recently (18-24 months ago), Lafleur anticipates significantly lower error rates (less than 35-50%) compared to typical PEAs.

Operational Focus and Expansion Potential

The immediate focus is on the execution of a 750-ton per day (tpd) mill operation, with potential for an increased ramp-up phase to 1100 tpd.

  • Primary Feed Source: Swanson is the prime source of mineralized material for Beacon within the next 12 months.
  • Future Feed Options: Possibilities include other deposits and custom milling for adjacent projects.
  • Mill Upgrade Potential: The mill can be upgraded as more projects are integrated.
  • PA Focus: The current PEA is focused on the combined Swanson and Beacon project.

Timeline to Production and Mill Restart

The PEA is scheduled for completion by the end of the year. Concurrently, work on restarting the Beacon Gold Mill is already in progress.

  • Mill Restart Activities: This includes cleanup, maintenance, and operational testing.
  • Team Deployment: A team of engineers (process, metallurgical, mechanical, electrical) is already at Beacon.
  • Operational Testing: The initial operational phase involves running the existing stockpile through the entire flowsheet (grinding, rod mill, ball mill, etc.) to ensure everything is tuned for smooth operation when Swanson ore is introduced in early 2026.

Bulk Sample and Pit Sequencing

A 80,000-100,000 ton bulk sample, essentially the first phase of mining at Swanson, will be used to validate costs and recoveries.

  • Ore Sorting Integration: This phase will incorporate ore sorting to potentially beneficiate the head grade. The specific ore sorting technology (laser, XRT, visual) is being evaluated based on Swanson's unique deposit parameters.
  • Testing and Processing: Portable ore sorting equipment may be used on-site. The sorted material will be trucked to Beacon and processed for at least a year, generating results, recoveries, and cash flow.
  • Pit Expansion: Following the bulk sample, the pit will continue to expand towards its final estimated size, potentially reaching 500,000 tons.

Critical Path Items for Restart

The team is currently focused on a short-term startup of the mill.

  • Short-Term Startup: This involves necessary repairs and maintenance to get the mill operational and process the existing stockpile. This ensures all equipment functions efficiently before Swanson ore is introduced.
  • Existing Stockpile: The availability of this stockpile is crucial for the initial testing and ramp-up.
  • Repair and Maintenance: Immediate repairs and maintenance are planned using existing funds, with further build-up anticipated.
  • Longer-Term Improvements: Studies for increasing mill efficiency and potential expansion have been conducted internally.
  • Mill Downtime: The mill has been idle for approximately 18 months.
  • Known Issues: Repairs are based on known issues identified after Monarch ceased operations in 2023.
  • Cost of Repairs: The cost for these short-term repairs is estimated to be low, ranging from $2-3 million initially, potentially up to $5-6 million.
  • Tailings Storage Facility: Repairs are also required for the tailings storage facility to enable full production. Geotechnical engineers will inspect and supervise this work.

Tolling and Custom Milling

While not a primary focus, tolling and custom milling are possibilities.

  • Primary Focus: Lafleur's main focus is on the 100% owned Swanson project due to its short-term production potential and existing lease.
  • Environmental Plans: An environmental closure plan and remediation plan are being developed for submission to the Quebec government.
  • PEA Presentation: PEA results will be presented to the Quebec government's natural resources department.
  • Mill Capacity: Lafleur believes the mill can be easily filled with ore from Swanson, with the PEA modeling solely using Swanson as the feed source to reach 750 tpd.
  • Custom Milling Interest: Companies have expressed interest in tolling or custom milling, and processing bulk samples. Many companies in the area have 15,000-20,000 tons of material they wish to process.

Refurbishment and Flowsheet Considerations

The PEA incorporates existing refurbishment work and mill knowledge.

  • ERM's Involvement: ERM engineers have visited the Beacon mill and Swanson project, gaining full awareness of past work.
  • Flowsheet Expertise: The metallurgical engineer involved has extensive experience with Mel Crow type mills and is familiar with the Beacon mill from previous work.
  • Metallurgical Test Results: Independent metallurgical test results from SGS will provide an assessment of recoveries and head grades from Swanson, which will be incorporated into the PEA.
  • Current Flowsheet: The PEA is currently focused on the existing flowsheet.
  • Expansion Plans: Past studies (e.g., by Marinar) have explored expanding the mill to 3,000 tpd, primarily requiring upgrades to crushing and potentially adding a CIL circuit. Lafleur notes that crushing is often a bottleneck in mill expansions. The current plan does not include a CIL circuit but may add a gravity circuit.

Open Pit Schedule and Cutoff Grades

Information on the initial strip ratio, mining rates, and the impact of ore sorting on effective cutoff grades for the Swanson open pit is still being finalized.

  • Ongoing Work: Lafleur is currently conducting this detailed work.
  • Scoping Study: A historical high-level scoping study existed, but the PEA will provide much more detailed numbers.
  • Future Results: These results are expected shortly.

Trucking and Logistics

Trucking ore from Swanson to Beacon covers a distance of approximately 50-60 km.

  • Outsourcing vs. Ownership: Lafleur is considering both scenarios, but a contractor scenario is likely for the initial phase.
  • Initial Operations: A small operation at Swanson will involve excavators and dump trucks. A crusher may also be on-site to reduce ore size.
  • Crushing for Ore Sorting: If ore sorting is implemented, crushing will be necessary.
  • Contractor Availability: Numerous experienced local trucking companies in Quebec's Abitibi region are available, allowing for competitive sourcing of services. Lafleur has contacted at least four to five trucking companies.

Precipitation, Security, and Refinery Contracts

These aspects will be addressed as part of the overall plan.

  • Gold Doré Processing: Similar to Marinar's past operations, the mill will produce gold doré, which will likely be sold to a third-party local company for refinement. The Canadian Mint is often outsourced for refinement.
  • Contractual Agreements: Contracts for these services will be in place.
  • Test Material Production: Gold production will commence during the test material runs as the mill ramps up.
  • Stockpiles: Both high-grade and low-grade stockpiles exist on-site.

Gold Price Assumption in PEA

Determining the gold price for the PEA is a critical consideration.

  • ERM Expertise: ERM, a multinational consultancy, possesses significant expertise in this area, including access to internal knowledge and market data.
  • Short Mine Life Consideration: Given the potentially shorter mine life of Swanson specifically (within its current lease), a higher gold price might be tested. This contrasts with projects with longer mine lives (15-25 years).
  • Resource Expansion: Lafleur plans to continue increasing resources through additional drilling across the Swanson project area and is exploring consolidation opportunities in the region.
  • Unprecedented Price Increases: The company notes unprecedented increases in gold prices ($100-$500 per ounce) seen in recent PEA and PFS reports globally.
  • EBITDA and Capex: The PEA will provide key financial metrics like EBITDA, capex, and sustaining capex, indicating operating margins. The focus will be on demonstrating profitability in the current market.

Capital Allocation and Regional Consolidation

Balancing capital allocation between exploration, organic growth, and acquiring regional assets to feed the mill is a strategic consideration.

  • Underground Resource at Swanson: Lafleur is exploring an underground resource at Swanson, with plans for deeper drilling to verify higher grades found in historical deep holes. This suggests a potential for underground mining in addition to the open pit.
  • Flow-Through Funding: The company anticipates receiving additional flow-through funding to support drilling efforts, particularly deep drilling at Swanson to upgrade inferred resources and increase tonnage.
  • PA Focus: The PEA will focus on an open-pit scenario, but an underground scenario is a strong possibility pending further drilling verification.

Conclusion and Next Steps

The PEA is nearing completion by the end of the year, at which point Lafleur will have firm numbers to discuss. The company is confident in its ability to restart the Beacon Gold Mill and bring the Swanson project into production, leveraging existing infrastructure and a detailed, advanced study approach. The integration of Swanson and Beacon, coupled with ongoing exploration and potential regional consolidation, positions Lafleur for future growth.
