# Mammoth Announces Gold Recoveries of up to 90% from Bottle Roll Tests on Material from Large Carneritos Area on its Tenoriba Gold-Silver Property, Mexico Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/mammoth-announces-gold-recoveries-of-up-to-90-from-bottle-roll-tests-on-material--daa102e6-79cb-4deb-8b05-c0b4a85d4172 Original source: https://money.tmx.com/en/quote/MTH/news/7586927646310466/mammoth-announces-gold-recoveries-of-up-to-90-from-bottle-roll-tests-on-material Publisher: tmx Original announcement: 2023-11-09T14:30:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Mammoth Resources Corp. - Ticker: MTH - Exchange: TSX - Region: Chihuahua State, Mexico - Primary commodity: Gold - Secondary commodities: Silver - Document categories: Metallurgy - Extracted: 2026-09-18 11:15:29 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Mammoth Resources Corp. announced successful cyanide bottle roll test results from its Tenoriba Gold-Silver Property in Mexico. Gold recoveries reached up to 94.7% for oxidized material and 74.7% for mixed oxidized-sulfide/transition material, with silver recoveries up to 58.9%. The rapid dissolution kinetics support the potential for low-cost heap leach processing. Reasoning: Strong metallurgical results from bottle roll tests on oxidized and mixed material, supporting the potential for heap leach processing at the Tenoriba property. - Positive factor: High gold recoveries \(>90% for oxidized material\) - Positive factor: Rapid dissolution kinetics \(majority within 12 hours\) - Positive factor: Potential for low-cost heap leach technology - Positive factor: QA/QC disclosed with SGS laboratory and QP sign-off Facts used in scoring: 6 ## Classification and evidence **High Recovery** Polarity: positive Definition: Recovery at or above the exceptional band for the commodity and processing route. Why it applies: Gold recoveries reached up to 94.7% in oxidized samples. Evidence · text > Gold recoveries in two bottle roll tests are greater than 90% for the oxidized material samples **Heap Leach Route** Polarity: neutral Definition: Processing via heap leach — lower CAPEX and OPEX, lower recovery expected. Why it applies: The release explicitly discusses the potential for heap leach technology. Evidence · text > bodes well for potential gold-silver recoveries by low-cost, heap leach technology **QA/QC Disclosed** Polarity: positive Story-specific tag Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: Release mentions SGS laboratory, check assays, and QP sign-off by Richard Simpson. Evidence · text > SGS lab QA/QC procedures were performed which includes check assays for gold and silver. **Bench Scale Only** Polarity: negative Definition: Only preliminary bench tests completed — no locked-cycle or pilot work. Why it applies: Results are from bottle roll tests, which are preliminary screening-level tests. Evidence · text > results from bottle roll tests performed on three composite samples **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: 6.
