The PEA evaluates a conventional open-pit, crushed heap-leach operation with a pre-tax NPV of $87 million and a 48% IRR based on $3,600/oz gold. Reasoning: The PEA demonstrates robust economics for a heap-leach operation with high IRR and rapid payback, though it relies on inferred resources. - Positive factor: Strong economic metrics with 48% pre-tax IRR - Positive factor: Low strip ratio of 0.8:1 - Positive factor: Rapid payback period of 1.7 years - Positive factor: Significant upside potential from undrilled targets - Negative factor: PEA includes inferred resources which are speculative - Negative factor: Low silver recovery \(13%\) Facts used in scoring: 3 ## Classification and evidence **PEA-Supporting** Polarity: neutral Definition: Resource estimate prepared to support a Preliminary Economic Assessment — early-stage study. Why it applies: The announcement presents a Preliminary Economic Assessment \(PEA\) for the project. Evidence · text > announced the results of a Preliminary Economic Assessment \("PEA"\) **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: The PEA includes inferred mineral resources which are considered speculative. Evidence · text > It includes inferred mineral resources that are considered too speculative geologically **QP/CP Signed** Polarity: positive Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience. Why it applies: Qualified Persons are named and have reviewed the technical information. Evidence · text > reviewed and approved by the relevant Qualified Persons **Heap Leach Route** Polarity: neutral Definition: Processing via heap leach — lower CAPEX and OPEX, lower recovery expected. Why it applies: the document describes a heap\_leach route \("heap-leach"\) **Single Domain Only** Polarity: negative Definition: Testing limited to one composite or domain — representativeness not established. Why it applies: only one composite was tested ## Extracted facts Stored fact records: 3.

Ashton, Richard Kern, Reinis N. Sipols - Resource group id: resource:cc4b9e4e49743a60f493 - Deposit or zone: Longstreet - Mining method: open\_pit - Material type: oxide - Resource basis: gross #### Resource Data - Category: inferred - Tonnes: 6550000 - Contained Metal: 105461 - Contained Unit: oz #### Review - Needs Review: No - Historical: No #### Dates - Event date: 2026-09-22T00:00:00.000Z Reasoning: The PEA mine plan uses a subset of the larger resource to demonstrate economic viability. - Positive factor: Establishes economic baseline for the project - Negative factor: Includes inferred resources which are speculative Evidence · text > The PEA mine plan designed pit processes approximately 6.55 million tons of ore containing 105,461 ounces of gold. #### Tags used in scoring **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: category is "inferred" **Cut-off Undisclosed** Polarity: negative Definition: High-grade interval reported without stating the cut-off grade used for compositing. Why it applies: no cutoff\_grade was stated **QP/CP Signed** Polarity: positive Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience. Why it applies: qp\_signed is true **No QP/CP Disclosure** Polarity: negative Definition: No Qualified Person or Competent Person named — lower credibility for the estimate. A QP/CP should be a member of a recognized professional association with relevant experience. Why it applies: no Qualified or Competent Person is named anywhere in the release **Resource Update** Polarity: neutral Definition: Revised estimate for an existing resource — compare to prior to assess progress. Why it applies: the release compares against a previous estimate **PEA-Supporting** Polarity: neutral Definition: Resource estimate prepared to support a Preliminary Economic Assessment — early-stage study. Why it applies: the release names the study this estimate supports ## Metallurgical Results (2) ### Fact 1 [Link to this fact](https://atlas-staging.minestarters.com/news/star-gold-corp-announces-positive-preliminary-economic-assessment-for-the-longst--e4c1f890-92af-4ada-a9ae-44280352c59b#fact-metallurgical-facts-1) Longstreet Gold-Silver Project · gold #### Identity - Project: Longstreet Gold-Silver Project - Commodity: gold - Region: usa\_nv - Reported Region: Nevada - Ticker: SRGZ #### Test Work - Processing Route: crushed heap-leach - Sample: metallurgical testing at McClelland Laboratories #### Recovery - Recovery: 84 % - Recovery Basis: actual\_test #### Review - Needs Review: No - Historical: No #### Dates - Event date: 2026-09-22T00:00:00.000Z Reasoning: The 84% gold recovery is an improvement over the 80% reported in the prior detailed metallurgical testing. - Positive factor: Recovery of 84% is solid for a heap-leach route - Negative factor: Lower than previous detailed testwork of 80%? No, 84% is an improvement over the 80% in RAG. Evidence · table > 84 Context: Gold recovery #### Tags used in scoring **Heap Leach Route** Polarity: neutral Definition: Processing via heap leach — lower CAPEX and OPEX, lower recovery expected. Why it applies: processing\_route matches the heap\_leach signal **High Recovery** Polarity: positive Definition: Recovery at or above the exceptional band for the commodity and processing route. Why it applies: 84% is at or above the exceptional band \(75%\) **Byproduct Commodity** Polarity: neutral Definition: The tested commodity is a byproduct rather than the primary economic driver. Why it applies: the release describes a byproduct credit ### Fact 2 [Link to this fact](https://atlas-staging.minestarters.com/news/star-gold-corp-announces-positive-preliminary-economic-assessment-for-the-longst--e4c1f890-92af-4ada-a9ae-44280352c59b#fact-metallurgical-facts-2) Longstreet Gold-Silver Project · silver #### Identity - Project: Longstreet Gold-Silver Project - Commodity: silver - Region: usa\_nv - Reported Region: Nevada - Ticker: SRGZ #### Test Work - Processing Route: crushed heap-leach - Sample: metallurgical testing at McClelland Laboratories #### Recovery - Recovery: 13 % - Recovery Basis: actual\_test #### Review - Needs Review: No - Historical: No #### Dates - Event date: 2026-09-22T00:00:00.000Z Reasoning: 13% silver recovery is quite low, limiting the silver byproduct contribution. - Negative factor: Very low silver recovery Evidence · table > 13 Context: Silver recovery #### Tags used in scoring **Heap Leach Route** Polarity: neutral Definition: Processing via heap leach — lower CAPEX and OPEX, lower recovery expected. Why it applies: processing\_route matches the heap\_leach signal **Low Recovery** Polarity: negative Definition: Recovery below the weak band for the commodity and processing route.
