Understanding Reserves & Resources
Proven Reserves (P1)
Economic portion of measured mineral resources with high confidence in tonnage, grade, and continuity. Supported by detailed sampling, engineering, and economic analysis. Basis for production planning and reserve reporting.
Probable Reserves (P2)
Economic portion of indicated (and sometimes measured) mineral resources with reasonable confidence. Less geological certainty than proven reserves but still bankable for financing. Often included in life-of-mine plans.
Measured & Indicated Resources (M&I)
Potentially economic deposits with reasonable to high geological confidence but requiring additional technical and economic studies before conversion to reserves. M&I resources represent future reserve potential.
Inferred Resources
Lowest confidence category - insufficient drilling to establish continuity. Cannot be converted directly to reserves - requires upgrading to M&I first through additional exploration. Represents long-term exploration upside.

Frequently Asked Questions
What are ANSS's total mineral reserves?
ANSS (Ansys Inc) reports total proven and probable mineral reserves of 30.8 million ounces of gold. This includes 12.5 million ounces of proven reserves (highest confidence) and 18.3 million ounces of probable reserves (high confidence). Reserves represent economically mineable material at current metal prices and operating costs, based on detailed mine plans.
What is ANSS's reserve life?
At current production rates of 2.8 million ounces per year, ANSS's reserves support approximately 11.0 years of mining operations. Reserve life is a key metric for sustainability - companies typically aim for 10+ years. Reserve life can be extended through brownfield exploration at existing mines, reserve upgrades from inferred/indicated resources, or acquisitions.
What is the difference between reserves and resources?
Reserves are economically viable, technically feasible, and legally extractable mineral deposits with detailed mine plans. They're classified as proven (highest confidence) or probable (high confidence). Resources are potentially economic deposits requiring further study, classified as measured (high confidence), indicated (moderate confidence), or inferred (low confidence). Resources may be converted to reserves with additional drilling, engineering, and economic studies.
What is ANSS's average ore grade?
ANSS's mineral reserves have an average grade of 2.1 grams per tonne (g/t) of gold. Higher grades mean more valuable metal per tonne of ore, reducing mining and processing costs per ounce produced. Premium deposits often exceed 3-5 g/t. Grade is critical for economics - a 2 g/t deposit requires processing 1,000 tonnes of ore to produce ~64 ounces of gold.
How does ANSS grow reserves?
Reserve growth strategies include: (1) Brownfield exploration - drilling at existing mines to extend deposits, (2) Resource conversion - upgrading inferred/indicated resources to reserves through additional drilling and studies, (3) Reserve optimization - mine plan improvements and technological advances, (4) Acquisitions - purchasing companies or projects with established reserves, (5) Greenfield discoveries - new deposit discoveries (highest risk, highest reward).
Why do ANSS's reserves change year-over-year?
Annual reserve changes reflect: (1) Depletion - production during the year reduces reserves, (2) Additions - exploration success and resource conversions add reserves, (3) Economic factors - commodity price changes affect economic cutoff grades, (4) Technical revisions - updated mine plans, metallurgy, or cost estimates, (5) Acquisitions/divestitures. Net reserve replacement ratio above 100% indicates sustainable operations.
