ARIS · Aris Mining Corporation

Current Thesis

Aris Mining is a two-asset Colombian gold producer whose margin arithmetic is currently wide: the Q2 2026 release of 2026-07-29 showed Segovia owner-mining all-in sustaining costs of $1,767/oz against a realized gold price of $4,450/oz, converting $321M of gold revenue into $179M of adjusted EBITDA in one quarter (trailing-twelve-month adjusted EBITDA $690M, adjusted net earnings $96M or $0.47 per share). The leg an investor is buying is the volume step on top of that margin: H1 2026 production of 148.0 koz was +31% versus H1 2025, full-year guidance stands at 300–350 koz, and the 5,000 tpd Marmato CIP plant is scheduled for first gold in Q4 2026, which the company frames as the bridge toward roughly 500 koz per year. The narrative is accelerating — the 2026-07-29 print raised the run-rate, the shares are 34.9% higher over three months into the 2026-09-03 close of $20.55, and the commissioning event that turns guidance into ounces has not occurred yet.

Bullish and bearish views on Aris Mining Corporation

The model's bull view on Aris Mining Corporation (ARIS), in brief: Q2 2026 (2026-07-29): 73.7 koz produced, Segovia 64.4 koz and Marmato 9.3 koz; gold revenue $321M at a $4,450/oz realized price; adjusted EBITDA $179M against $690M trailing twelve months. The bear view: Consolidated cost is not Segovia's cost: H1 2026 combined AISC was $1,974/oz versus Segovia's $1,767/oz in Q2, and that gap only closes if Marmato's new plant runs. Both cases follow in full.

Bull Case

• Q2 2026 (2026-07-29): 73.7 koz produced, Segovia 64.4 koz and Marmato 9.3 koz; gold revenue $321M at a $4,450/oz realized price; adjusted EBITDA $179M against $690M trailing twelve months.
• Segovia feed quality is doing the work: 202.5 kt processed at 10.23 g/t in Q2 2026, at the 3,000 tpd capacity installed since June 2025, at $1,767/oz owner-mining AISC.
• The build is self-funded so far: $426M cash at 2026-06-30 while spending $121M of growth capital in the quarter ($78M Marmato, $31M Segovia).
• Marmato contributed only 17.1 koz in H1 2026 against a 2026 range of 35–50 koz, so the second-half delta is dated and checkable rather than a vague ramp story; the CIP plant was reported on schedule for Q4 2026 first gold, 3,000 tpd by year-end and full 5,000 tpd in late 2027.
• The metal does not need new highs for the thesis: gold rebounded about 2% to $4,478 on 2026-09-03 (USAGold daily report), still well under the 2026-01-28 record of $5,602.22, and Q2 was already priced at $4,450/oz realized.
• Sell-side compilation sits above the tape: stockanalysis.com's compiled 12-month consensus stood at $37.0 in late August 2026.

Bear Case

• Consolidated cost is not Segovia's cost: H1 2026 combined AISC was $1,974/oz versus Segovia's $1,767/oz in Q2, and that gap only closes if Marmato's new plant runs.
• H1 2026 production of 148.0 koz sits below half the 300–350 koz guide; the year depends on a second-half weighting that a commissioning slip would remove.
• Gold itself is off its high — spot was $4,335.79 on 2026-09-02, roughly a fifth below the 2026-01-28 record — while the equity is up 34.9% over three months. That is operating leverage running ahead of the metal, and it works in reverse.
• Single-jurisdiction concentration: both producing assets, Segovia and Marmato, are in Colombia. Royalty, permitting and security risk is undiversified by design.
• Capital intensity is live: $121M of growth capital in a single quarter against $426M of cash means a materially weaker gold tape reopens the funding question before Marmato reaches nameplate in late 2027.
• Coverage is thin and the compilations disagree — TipRanks showed a $29.34 average drawn from 2 analysts while ChartMill compiled 11 forecasts averaging $29.16 (both observed 2026-09-04). A consensus assembled from a handful of estimates moves a long way on one revision.

Setup & Price Structure

• The 2026-09-03 reference close was $20.55, 9.4% under the 52-week high of $22.68, with RSI(14) at 63.7 after a 34.9% three-month advance. That is a trend in force and momentum elevated without reaching the readings that usually mark exhaustion.
• The advance has to clear $22.68 to extend; below, $17.50 is the level where a weekly close cuts through the bulk of the three-month move and leaves the volume-step story without price confirmation.
• Positioning observables: no insider transactions appear in the recent filings window. The one dated ownership move is corporate rather than insider — Aris cut its Seasif Exploration stake from 20.4% to 9.8% through a C$77,500 privately brokered share sale reported 2026-08-05, small enough to be housekeeping.
• Attention is not crowded: the name's recent tape mentions are aggregator lists ("12 Materials Stocks Moving In Thursday's After-Market Session", 2026-09-03) rather than dedicated retail-sentiment coverage. There is no earnings date inside the next 30 days to compress positioning against.

Catalyst Calendar (next 30 days)

• 2026-09-15/16 — FOMC decision with a Summary of Economic Projections (Federal Reserve calendar). The real-rate path sets the gold price that sets Aris's realized price; this is the only hard-dated event inside the window.
• ~2026-10-06 (est.) — Q3 2026 production release. Q2 production was released 2026-07-07, so the analogous Q3 date falls just outside 30 days. First quantitative read on whether the H2 weighting behind 300–350 koz exists.
• ~2026-11-04 (est.) — Q3 2026 results and MD&A, where consolidated AISC and the Marmato commissioning language get updated.
• Q4 2026 (company guidance, undated) — Marmato CIP plant first gold.

What Would Change Our Mind

The cleanest break is schedule. If the Q3 update changes the Marmato language from on schedule for Q4 2026 first gold to a 2027 window, the volume step that justifies the current multiple moves out a year and the 35–50 koz Marmato range collapses toward its lower end. The second break is guidance — a Q3 production figure below the Q2 level of 73.7 koz, or an explicit revision under 300 koz, removes the second-half weighting the whole 2026 case rests on. On price, a weekly close below $17.50 cuts through the bulk of the June-to-September advance and would say the market has repriced the ramp regardless of what the company says about it. A third path is the metal: gold losing $4,000 on a weekly close would compress the $4,450/oz realized price that produced $179M of quarterly EBITDA, and a miner carrying this much operating leverage does not hold a bid through that. Finally, the story would read as saturated rather than accelerating if mainstream coverage of the Marmato start-up arrives and the shares fail to take out $22.68 on it.

Correlation Notes

• The cluster tag on this name reads Oil, energy & geopolitical, alongside AMR, HCC, BTU, HP and NOG, with a weekly trail of 05-07 maturing, 08-07 dead and 09-03 accelerating. That grouping links through the commodity and real-rate channel rather than a shared demand curve: the coal and oil names key off met coal, thermal coal and crude, while Aris keys off spot gold and Colombian operating risk. A crude selloff does not mechanically transmit to ARIS; a hawkish real-rate repricing hits both.
• The higher-correlation reference set is gold-miner beta (the GDX/GDXJ complex) and the gold price itself: $5,602.22 on 2026-01-28, $4,335.79 on 2026-09-02, about $4,478 on 2026-09-03.
• Because the cluster's own reading flipped from dead on 2026-08-07 to accelerating on 2026-08-11 and again on 2026-09-03, its signal on this name is weak in both directions — the group's heat neither supports nor excuses the single-name structure here.
