Minestarters Atlas analysis
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 factors
- Strong silver recoveries (>80%) achieved at both sites
- High-grade silver concentrates produced (up to 2,512 g/t Ag)
- Conventional flotation route successfully demonstrated
Negative factors
- Results are from open-circuit batch tests only; locked-cycle testing not yet completed
- Presence of arsenic and bismuth in copper concentrates likely to attract smelter penalties
- Gold recovery is relatively low (40.7% - 54.2%)
Facts used in scoring: 5
Classification and evidence
Bench Scale Onlynegative
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 Orenegative
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 Routeneutral
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 Onlynegative
Testing limited to one composite or domain — representativeness not established.
Why it applies: only one composite was tested

How Atlas produces this analysis
Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
