Key catalyst
Marmato CIP first-gold and ramp-up • 2026-12-31
Base target: $15 / p=45% prob
Biggest risk
Q3 production declined sequentially and management shifted its outlook toward the bottom of guidance. Further Segovia grade or partner-feed weakness, Marmato commissioning delays, or higher costs could pressure the shares.
Invalidation
Break below $11 or thesis failure.
What would change my mind?
Successful Marmato first gold, a stronger Segovia ramp, and recovery toward the 2026 production floor could improve cash-generation visibility. These outcomes are not yet demonstrated in final Q3 results.

Commentary
Company-source tone is mixed: Q3 project milestones are constructive, but lower sequential production and a shift toward the guidance floor weaken the near-term thesis. The scheduled November 4 release has not occurred as of this report. No verified analyst revisions, post-result price reaction, or sufficient social, options, short-interest, or employee data are available; zero sentiment-field values denote unavailable data, not neutral readings.

    Marmato CIP first-gold and ramp-up
    Aris says its 5,000-tpd CIP plant remains on track for first gold in Q4. Cascabel 3 tailings commissioning and ore stockpiling are progress markers, but Q3 Marmato output fell to 5.8 koz amid planned flotation downtime. Commissioning timing and the subsequent ramp remain the decisive tests. [#PR-2026-10-07] Aris Q3 production.

Short-term Catalysts

Next few weeks

  • Q3 production lowers the 2026 guidance test
    2026-11-04
    Preliminary Q3 output was 69.3 koz, down from 73.7 koz in Q2. After 217.3 koz over nine months, Aris now expects the lower end of its 300–350 koz full-year range; reaching 300 koz requires about 82.7 koz in Q4. The November 4 results will test costs and cash generation behind that production update. [#PR-2026-10-07] Aris Q3 production; [#PR-2026-10-21] results date.

Long-term Catalysts

Months to a year

  • Toroparu prefeasibility and construction decision
    2027-03-31
    The company targets completion of the Toroparu prefeasibility study in Q4 2026 and a potential construction decision in early 2027. The project remains optionality rather than committed near-term production; economics, permitting, and funding need verification after the study. [#PR-2026-10-07] Aris Q3 production.

Risks

  • Gold-price sensitivity, capital spending, and Colombian operating and permitting risks remain material.
  • Marmato CIP commissioning and 2027 ramp-up may slip; Q3 Marmato production was reduced by planned flotation-plant downtime. [#PR-2026-10-07]
  • Reaching the 300 koz guidance floor requires approximately 82.7 koz in Q4 after 69.3 koz in Q3. [#PR-2026-10-07]
  • Segovia output slipped despite higher tonnes processed; lower processed grade and earlier constraints on contract-miner explosives complicate the ramp. Aris says the explosives issue was resolved in September. [#PR-2026-10-07]
