Conventional flotation successfully produced high-grade silver, copper, lead, and zinc concentrates, with silver recoveries exceeding 80% at both sites. Reasoning: The results establish a strong metallurgical baseline for the PEA with high silver recoveries, though technical risk remains due to the lack of locked-cycle testing and potential smelter penalties for deleterious elements. - Positive factor: High silver recoveries \(80.8% and 84.3%\) - Positive factor: Strong concentrate grades for silver and lead - Positive factor: Conventional flotation flowsheet successful - Negative factor: Bench-scale batch tests only \(no locked-cycle testing completed\) - Negative factor: Presence of arsenic and bismuth in copper concentrates likely to attract smelter penalties - Negative factor: Lower gold recoveries \(40.7% at MSN\) - Negative factor: Limited sample representativeness \(preliminary results\) 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 deportment to tailings and the role of gold tellurides \(calaverite\) are noted as requiring further investigation. Evidence · text > Calaverite \(gold telluride\) was identified at 0.3%. **Deleterious Elements Present** Polarity: negative Story-specific tag Definition: Penalty elements \(arsenic, antimony, etc.\) or refractory concerns noted in the release. Why it applies: Both copper concentrates contain arsenic and bismuth at levels expected to attract smelter penalties. Evidence · text > Both copper concentrates contain arsenic and bismuth at levels expected to attract smelter penalties. **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: the document describes a flotation route \("flotation"\) **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.
