Presentation Template for Mining and Resources: Investor Briefings, Feasibility Presentations, and Stakeholder Reports

Mining presentations carry regulatory requirements that directly constrain language — particularly for companies listed on the Toronto Stock Exchange or the TSX Venture Exchange, where National Instrument 43-101 governs every public disclosure of mineral resource and reserve estimates. An investor day deck that uses phrases like "promising results" or "expected to contain" in connection with undisclosed resource estimates can trigger a regulatory filing requirement or, worse, a securities commission inquiry. Precision is not a preference in mining — it is a legal obligation.

This guide covers the primary presentation formats in the mining sector: NI 43-101 compliant resource briefings, project feasibility presentations, investor day decks, community and stakeholder presentations, and safety reporting.

NI 43-101 Compliant Resource Briefing

NI 43-101 is the Canadian standard for public disclosure of scientific and technical information about mineral projects. Any mining company with securities listed in Canada — and any company marketing to Canadian investors — must comply with its requirements when presenting resource estimates.

Core NI 43-101 disclosure rules in presentations:

Qualified Person (QP) requirement: Every scientific and technical disclosure must be based on work supervised by or reviewed by a Qualified Person. The QP must be named in the presentation or in an accompanying filing. The slide disclosing the resource estimate should carry a footnote: "Resource estimate prepared under the supervision of [Name], [P.Eng./P.Geo.], a Qualified Person as defined by National Instrument 43-101." Without the QP attribution, the disclosure is non-compliant.

Resource vs. reserve — use the correct term: This is the most common error in mining presentations. A Mineral Resource is a concentration of material with reasonable prospects for eventual economic extraction — it is a geological estimate. A Mineral Reserve is the economically mineable part of a Mineral Resource — it requires a feasibility study or pre-feasibility study. Do not use the word "reserve" when the project is at the resource stage. Do not call anything a resource unless it meets the CIM Definition Standards classification.

Mandatory disclosure categories:

| Category | Definition | Geological confidence | |----------|-----------|----------------------| | Inferred Resource | Reasonable estimate, limited sampling | Lowest — tonnage and grade estimated but not verified | | Indicated Resource | Sufficient sampling for reasonable assumption of continuity | Moderate — detailed plans with economic parameters possible | | Measured Resource | Sufficient detail for detailed mine planning | Highest — detailed economic parameters applicable | | Probable Reserve | Indicated (sometimes Measured) + economic viability demonstrated | Feasibility or pre-feasibility study required | | Proven Reserve | Measured + economic viability demonstrated | Feasibility study required |

Resource estimate slide format:

Present resource estimates in a table with columns for: Category, Tonnage (Mt), Grade (g/t Au for gold, % for base metals, or applicable unit), and Contained Metal (Moz for gold, kt or Mt for base metals). Include the cut-off grade and the basis for it. State the effective date of the estimate. Reference the technical report (NI 43-101 Technical Report, filed on SEDAR/SEDAR+) from which the estimate is drawn.

What cannot be said without a technical report: Do not present resource figures that have not been disclosed in a current technical report, unless the presentation is contemporaneous with a technical report filing. Presenting a revised resource estimate in a slide before the supporting technical report is filed on SEDAR+ is a regulatory violation.

Project Feasibility Presentation

Feasibility study presentations are made to boards of directors authorizing a construction decision, to lenders conducting project finance due diligence, and to investors at a production decision announcement.

Recommended structure:

| Slide | Content | Key metrics | |-------|---------|-------------| | 1 | Project overview | Location, ownership, commodity, development stage | | 2 | Resource and reserve | NI 43-101 compliant table, mine life calculation | | 3 | Mine plan | Open pit or underground, production profile by year, strip ratio (open pit) | | 4 | Processing | Metallurgical recovery, process flowsheet, capacity (tpd) | | 5 | Capital cost | Initial CapEx and sustaining CapEx, contingency percentage, basis of estimate (AACE class) | | 6 | Operating cost | AISC (All-In Sustaining Cost) per ounce/pound, breakdown by category | | 7 | Economic analysis | NPV (after-tax, at base-case metal price), IRR, payback period, sensitivity table | | 8 | Environmental and permitting | EIS status, permits required vs. received, anticipated permitting timeline | | 9 | Project schedule | Construction timeline, commissioning, first production | | 10 | Project finance | Funding plan: equity, debt (project finance, streaming, royalty), funding gap |

Capital cost estimate class: Mining feasibility studies should state the AACE cost estimate class. A Class 3 estimate (feasibility, ±15–20% accuracy) supports a production decision and project finance. A Class 4 estimate (pre-feasibility, ±20–30%) may not. Investors and lenders distinguish between these; presenting a pre-feasibility number as a feasibility estimate misrepresents the confidence level.

AISC (All-In Sustaining Cost): The World Gold Council definition of AISC includes cash operating costs, royalties, sustaining capital, and corporate G&A. Present AISC against the current spot price and your base-case price assumption to show the margin. Show AISC on the cost curve for the relevant commodity to position the project relative to industry peers.

Sensitivity analysis: Present a sensitivity table showing NPV and IRR at ±10% and ±20% changes in metal price, CapEx, and operating cost. The metal price sensitivity dominates for commodity projects; the CapEx sensitivity matters most for high-capex underground or deep open pit projects. Show the base case in the center column with sensitivities to each side.

Investor Day Deck with Reserve Estimates

Investor day presentations for producing mining companies must balance a comprehensive operational review with forward-looking statements that comply with securities disclosure requirements.

Operational performance review:

Present gold equivalent ounces produced (or copper pounds, coal tonnes, etc.) for the period against guidance. Show costs: AISC per ounce year-over-year. Safety: Total Recordable Injury Frequency Rate (TRIFR) per million hours worked. Environmental: significant environmental incidents (number and category).

Reserve and resource update disclosure:

Annual reserve and resource estimates are a material disclosure event. When presenting updated reserves, show the reconciliation to the prior year: beginning reserves + additions (new drilling/conversions) − depletion (mining) − revisions (economic, geological) = ending reserves. Investors need to see that the reserve base is sustainable, not just the ending number.

Forward guidance: Provide production guidance in ounces/tonnes and cost guidance in AISC per unit for the forward period. Guidance is a forward-looking statement — include the standard disclaimer and the material assumptions underlying it (metal price, exchange rate, throughput assumption). State when guidance is expected to be updated.

Community and Stakeholder Presentation

Stakeholder presentations are made to local communities, Indigenous groups, local governments, and NGOs. These audiences did not request the project and may not support it. The presentation must acknowledge this reality.

Structure for community consultation meeting:

Lead with listening, not informing. If this is a consultation meeting under UNDRIP (UN Declaration on the Rights of Indigenous Peoples) or applicable law, the structure is not "here is what we are going to do." It is "here is what we are proposing — your feedback will shape the project."

Project overview: Location, size, proposed activities, timeline. Use maps at a scale that is relevant to the community — property boundaries that are meaningful to residents, not a geological claim map.

Environmental and social impact summary: What impacts are anticipated? Don't bury adverse impacts in appendices. Communities that discover withheld information in subsequent reporting become permanent adversaries. State the adverse impacts — noise, traffic, groundwater drawdown, habitat disturbance — and the mitigation measures for each.

Local hiring and procurement commitments: Employment projections by phase (construction vs. operations), skills training programs, local supplier preference policy. Quantify: "We anticipate hiring 240 construction workers, of whom 60% will be sourced from within 50km of the project."

Grievance mechanism: Explain how community members can raise concerns — who to contact, what the response timeline is, and how grievances are tracked and reported. Regulators increasingly require a documented grievance mechanism as a condition of permit.

Safety Reporting Presentation

Mine safety reporting is presented to boards, regulators, investors, and employees. The primary metric is TRIFR (Total Recordable Injury Frequency Rate) — the number of recordable injuries per million hours worked.

Safety performance dashboard:

• TRIFR: current period vs. prior period vs. industry benchmark
• Lost Time Injury Frequency Rate (LTIFR) separately from TRIFR
• Severity Rate: lost days per million hours worked
• High-Potential Incidents (HiPo): incidents that did not cause injury but had the potential to — these are the leading indicators that determine future injury rates
• Fatalities: any fatality warrants its own slide with full disclosure of circumstances and corrective action

Leading indicator disclosure: Trailing metrics (TRIFR, LTIFR) measure past performance. Leading indicators predict future performance: percentage of safety inspections completed, near-miss reporting rate, percentage of high-potential incidents investigated to root cause within target timeframe. Boards that review only trailing metrics are always looking backward.

Significant incident review: For any significant incident during the period, present: what happened, the cause investigation (5-why or bow-tie methodology), what was changed as a result, and the status of corrective action items. The board presentation should include this review — a board that receives an injury rate without understanding the incidents cannot provide meaningful governance oversight.
