Aris Mining is in the middle of a transition from a two-mine mid-tier gold producer to something materially larger, and the second-quarter print is the cleanest evidence yet that the transition is being self-funded rather than equity-funded. The company produced roughly 73,000 ounces of gold, sold roughly 72,000 ounces at an average realized price comfortably above $4,400 per ounce, and generated $179 million of adjusted EBITDA on $330 million of gold revenue. The more important observation is that the company invested $166 million in growth and expansion capital in the first half of the year, primarily to bring the new Marmato carbon-in-pulp plant into production, and still exited the half with a stronger net cash position than it entered. The equity re-rating, in our view, depends on whether the market credits that self-funding track record or continues to discount the equity for the apparent $1 billion-plus of growth capex that the project pipeline implies over the next two to three years.
The mechanism behind the print is straightforward and worth laying out. Realized gold prices declined by roughly 8% from the first quarter, but gold sold only declined by 4%, and the average grade at Segovia improved as the second mill continued to ramp up. The Marmato mine, the smaller of the two operating assets, posted a 19% sequential production increase and is currently running at a small fraction of the throughput that the new 5,000 tonne-per-day carbon-in-pulp plant is designed to deliver. First gold from the new Marmato plant is scheduled for the fourth quarter of 2026, which means the next six months are the period when the equity story pivots from "we are building it" to "we are running it." The market is pricing the company roughly as a producing gold miner with optionality on growth, in our reading of the share price, rather than as a growth-stage developer, and that gap between perception and the operational reality is the trade.
The single most important risk is execution: first gold from Marmato's new carbon-in-pulp plant is now approximately four months away, and any meaningful slippage from the late-2026 target would compress the multiple on the existing production base. The secondary risk is a re-rating of the gold price itself, because the cash flow profile is now large enough - roughly $690 million of trailing twelve-month adjusted EBITDA - that a sustained move in realized prices below $3,500 per ounce would force a recalibration of growth capex and net-debt assumptions. The falsifiable clock is the fourth quarter itself: the Marmato commissioning update, the 2026 full-year production print, and the initial Toroparu feasibility study results due in the second half of 2026 are the three data points that should test the thesis. Investors who believe the Marmato plant should commission on schedule and the gold price should hold above $3,500 per ounce through year-end 2027 may see the equity as mispriced at current levels; investors without conviction on either input may want to wait for the September quarter operational update before sizing a position. The third-quarter print, expected in early November, should provide the first read on the Marmato commissioning progress, the second-mill ramp-up at Segovia, and the year-to-date tax payments, which have been elevated in the first half.
