Is ARIS a Buy or a Sell? The Bull and Bear Case (2026)
Last updated July 2026
Short answer
Both cases are real, which is why the question is contested. The bull case for Aris Mining Corporation (ARIS) rests on The Marmato Lower Mine plant coming online: The new 5,000 tonne per day CIP plant is the single biggest variable in the next two years of results. The bear case rests on concentration is the defining risk: essentially all current production is in Colombia, which brings permitting delays, community and security issues, informal and illegal mining activity around the titles, tax and royalty changes, and peso volatility. We do not give a verdict. What follows is each case at full strength, so you can decide which set of assumptions you actually believe. Walnut is not an investment adviser.
Aris Mining produces gold from the Segovia complex in Antioquia, Colombia, and the Marmato mine in Caldas, Colombia. Segovia is the engine: it delivered roughly 64 thousand ounces in the second quarter of 2026 from ore grading above 10 grams per tonne, which is high by industry standards. Segovia is also unusual in how it sources ore. Alongside its own underground development, Aris buys ore from formalized local small-scale miners working within its titles and processes it through the company plant, an arrangement that adds volume without the full capital cost of developing every heading itself. Marmato is the growth story: a 5,000 tonne per day carbon-in-pulp plant tied to the Lower Mine is under construction, with first gold targeted for the fourth quarter of 2026. Beyond the two producing assets sit the Soto Norte joint venture in Santander, the Toroparu project in Guyana, and exploration ground in Canada. The financial picture as of August 2026 reflects both rising volumes and a very strong gold price. Trailing twelve month revenue is roughly $1.27 billion against roughly $928 million for full-year 2025, and trailing net income of roughly $285 million is several times the roughly $78 million reported for 2025. Second-quarter 2026 gold revenue was roughly $321 million on about 72 thousand ounces sold at an average realized price near $4,450 an ounce, producing roughly $179 million of adjusted EBITDA and roughly $94 million of net income. The company ended June with roughly $426 million of cash against roughly $506 million of debt, and it is spending heavily, roughly $121 million of capital in the quarter, most of it at Marmato. Consolidated all-in sustaining costs of roughly $1,986 an ounce are not low for the industry, but at current gold prices the margin is wide enough to fund the build from operations.
The bull case for ARIS
1. The Marmato Lower Mine plant coming online
The new 5,000 tonne per day CIP plant is the single biggest variable in the next two years of results. Mills are on site and mechanical installation is underway, with first gold guided for the fourth quarter of 2026 and a ramp through 2027. If it commissions on schedule, Marmato moves from a marginal contributor of roughly 35,000 to 50,000 ounces in 2026 toward a materially larger share of group output, which is what underpins management's stated path toward roughly 500,000 ounces a year.
2. Segovia throughput and grade
Segovia is still where the cash comes from, and the company is investing in underground development to lift utilization toward the plant's full 3,000 tonne per day capacity. Second-quarter all-in sustaining costs at Segovia of roughly $1,767 an ounce on owner mining leave a wide margin at prevailing gold prices. The variable to watch is whether grade holds as tonnage rises, since the mine's economics have historically leaned on unusually high head grades rather than scale.
3. Gold price leverage and an unhedged balance sheet
With realized prices near $4,450 an ounce against consolidated costs near $1,986, Aris is capturing a very large per-ounce spread, and the trailing earnings jump reflects that more than it reflects volume growth. That leverage runs in both directions. The company pays no dividend and is directing free cash into construction, so the equity is a fairly direct expression of the gold price rather than a yield instrument.
4. The development pipeline behind the producing mines
Soto Norte, a joint venture in Santander, has completed a prefeasibility study pointing to roughly 263,000 ounces a year and is working through environmental studies. Toroparu in Guyana has a prefeasibility study due in the second half of 2026 with a construction decision targeted for early 2027, and its earlier economic assessment indicated roughly 235,000 ounces a year. Neither is funded or permitted for construction yet, so both sit in the option-value category rather than the base case.
The bear case for ARIS
Concentration is the defining risk: essentially all current production is in Colombia, which brings permitting delays, community and security issues, informal and illegal mining activity around the titles, tax and royalty changes, and peso volatility. Soto Norte in particular has drawn environmental opposition given the sensitivity of high-altitude paramo ecosystems in Santander, and its timeline depends on approvals outside the company's control. Execution risk at Marmato is concrete and near-term, since commissioning delays or a slow ramp would push the growth thesis right at a time when capital spending is elevated. Costs are another pressure point: consolidated all-in sustaining costs near $2,000 an ounce mean the wide margins visible today are a function of an unusually high gold price, and a sharp retracement would compress cash flow quickly. Public sources reviewed in August 2026 did not identify an active United States securities fraud class action against Aris Mining, but the company operates under Colombian and Canadian regulatory regimes and routine legal and regulatory matters are disclosed in its filings.
The bear case deserves the same attention as the bull case, and usually gets less. If you are holding ARIS already, the question is not whether these risks exist but whether any of them has moved from possible to actually happening in the reported numbers.
Where analysts land on ARIS
Too few analysts publish on ARIS for a consensus target to mean anything, so there is no professional average to weigh against your own view. That cuts both ways: less informed opinion to lean on, and less of it already priced in. The ARIS forecast page covers what coverage does exist.
How is ARIS valued? (as of August 2026)
Snapshot for ARIS as of August 2026, sourced from Yahoo Finance and may be delayed. Valuation figures move with price and earnings; verify the current numbers with your broker before deciding.
- Revenue (TTM): ~$1.27 billion
- Net income (TTM): ~$285 million, EPS ~$1.38
- Market cap: ~$3.6 billion
- P/E (trailing / forward): ~12.6 / ~7.0
- EV/EBITDA: ~5.2 on ~$706 million EBITDA
- Cash / total debt: ~$426 million / ~$506 million
The valuation is built on earnings that inflected sharply: full-year 2025 net income was roughly $78 million and the trailing twelve month figure is roughly $285 million, so the trailing multiple is measuring a very recent step change rather than a settled run rate. A forward P/E near 7 and EV/EBITDA near 5 sit below where larger, more geographically diversified gold producers typically trade, which is the market pricing Colombian concentration and construction risk. The company pays no dividend and is directing cash into the Marmato build.
How do you decide if ARIS is a buy?
Rather than asking whether ARIS is a buy in the abstract, it tends to help to answer four questions:
- Thesis: do you believe the bull case above, and is it still true today?
- Time horizon: a single stock can be volatile, so a longer horizon absorbs more of the swings.
- Position sizing: a thesis can be right and the sizing still wrong; decide how much of your portfolio one name should be.
- Overlap: check whether you already hold ARIS indirectly through an index or sector ETF before adding more.
What would change your mind on ARIS
Write the tripwires down before you need them. Deciding what would falsify your view is far harder once a position is moving against you.
- Bull case breaks if: The Marmato Lower Mine plant coming online stalls in the reported numbers rather than in the narrative around them.
- Bear case breaks if: concentration is the defining risk: essentially all current production is in Colombia, which brings permitting delays, community and security issues, informal and illegal mining activity around the titles, tax and royalty changes, and peso volatility fails to materialise over several reporting periods while the drivers keep compounding.
- Neither matters if: the position has grown large enough that being wrong would damage the whole portfolio. Sizing overrides the argument.

FAQ
Is ARIS a good stock to buy right now?
+
That depends on which case you find more convincing, and both are on this page. The bull case rests on The Marmato Lower Mine plant coming online, with revenue (ttm) at ~$1.27 billion. The bear case rests on concentration is the defining risk: essentially all current production is in Colombia, which brings permitting delays, community and security issues, informal and illegal mining activity around the titles, tax and royalty changes, and peso volatility. If you believe the thesis, the real questions become sizing and overlap rather than timing. Walnut is not an investment adviser and this is not a recommendation.
Should I sell ARIS?
+
Nobody can answer that for you, and the honest version of the question is narrower: has anything changed in the reason you bought it? The bear case on this page is the place to check. Concentration is the defining risk: essentially all current production is in Colombia, which brings permitting delays, community and security issues, informal and illegal mining activity around the titles, tax and royalty changes, and peso volatility. If that risk is what you were worried about and it is now playing out, that is a real signal. If the price simply fell while the thesis held, that is a different situation entirely. Walnut is not an investment adviser.

What does Aris Mining Corporation do?
+
Aris Mining is a Vancouver-based gold producer whose output comes from the Segovia and Marmato underground mines in Colombia, with development projects in Guyana and Canada.
What would have to change for ARIS to stop being worth holding?
+
Decide that in advance, because it is far harder to think clearly once a position is moving against you. The concrete tripwires here: the driver behind the bull case (The Marmato Lower Mine plant coming online) stalling in the reported numbers rather than in the narrative, the risk above (concentration is the defining risk: essentially all current production is in Colombia, which brings permitting delays, community and security issues, informal and illegal mining activity around the titles, tax and royalty changes, and peso volatility) turning from a possibility into a reported fact, or the position growing large enough that a bad outcome would matter to your whole portfolio regardless of who is right.
What company is ARIS stock?
+
ARIS is Aris Mining Corporation, a gold producer headquartered in Vancouver with operating mines in Colombia and development projects in Colombia, Guyana and Canada. The ticker is worth double-checking in older articles, because ARIS in the United States previously carried Aris Water Solutions, an unrelated Permian Basin water infrastructure company.
Where does Aris Mining actually produce gold?
+
Almost all of it comes from two underground operations in Colombia. Segovia in Antioquia produced roughly 64 thousand ounces in the second quarter of 2026 from high-grade ore, and Marmato in Caldas added roughly 9 thousand ounces. Soto Norte in Santander, Toroparu in Guyana and exploration ground in Canada are development stage, not producing.
Is Aris Mining profitable?
+
Yes. Trailing twelve month net income is roughly $285 million on roughly $1.27 billion of revenue, a margin near 22 percent. That is a large step up from full-year 2025 net income of roughly $78 million, driven by both higher production and an unusually high realized gold price near $4,450 an ounce in the second quarter of 2026.
