# Titiminas Silver Reports Preliminary Metallurgical Test Results: Conventional Flotation Produces Copper, Lead and Zinc Concentrates at the Madre Sierra Silver Mine and a Copper-Silver Concentrate at Madre Sierra Norte Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/titiminas-silver-reports-preliminary-metallurgical-test-results-conventional-flo--2ef1bd4c-005f-49c4-86c9-90c2f648ef6d Original source: https://orestocks.com/company/TITI.V/press-releases/4947160715479438 Publisher: orestocks Original announcement: 2026-10-07T11:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-10-07T11:34:25.932Z Atlas analysis updated: 2026-10-07T11:34:25.932Z - Company: Titiminas Silver Inc. - Ticker: TITI.V - Exchange: Unavailable - Region: Junín, Peru - Primary commodity: Silver - Secondary commodities: Copper, Lead, Zinc, Gold - Document categories: Metallurgy - Extracted: 2026-10-07 11:34:26 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary Titiminas Silver has reported preliminary metallurgical test results from the Madre Sierra Silver Mine and Madre Sierra Norte. Conventional flotation successfully produced silver-rich concentrates, with silver recoveries exceeding 80% at both locations, though gold recovery remains lower and concentrate impurities like arsenic were noted. Reasoning: The release reports the first metallurgical test results for two projects, showing promising silver recoveries but noting technical risks regarding gold deportment and concentrate impurities. - Positive factor: Strong silver recoveries \(>80%\) achieved at both sites - Positive factor: High-grade silver concentrates produced \(up to 2,512 g/t Ag\) - Positive factor: Conventional flotation route successfully demonstrated - Negative factor: Results are from open-circuit batch tests only; locked-cycle testing not yet completed - Negative factor: Presence of arsenic and bismuth in copper concentrates likely to attract smelter penalties - Negative factor: Gold recovery is relatively low \(40.7% - 54.2%\) Facts used in scoring: 5 ## Classification and evidence **Bench Scale Only** Polarity: negative Definition: Only preliminary bench tests completed — no locked-cycle or pilot work. Why it applies: All flotation tests reported were open-circuit batch tests; locked-cycle testing has not yet been completed. Evidence · text > All flotation tests reported in this release were open-circuit batch tests. Locked-cycle testing has not yet been completed. **Refractory Ore** Polarity: negative Definition: Ore requires oxidation/pressure treatment before recovery — a processing and recovery risk. Why it applies: Gold recovery is low \(40.7%\) and the company notes the need to investigate gold deportment to tailings and the role of gold tellurides. Evidence · text > The deportment of gold to the tailings, including the role of gold tellurides, will be investigated in the next phase of testing. **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: The process involves conventional crushing, grinding, and froth flotation. Evidence · text > Both materials responded to conventional crushing, grinding and froth flotation **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: 5.
