An announcement from Excelsior Mining ( (TSE:GCU) ) is now available.
Gunnison Copper has released an updated Preliminary Economic Assessment for its Gunnison Copper Project in Arizona, outlining a conventional open-pit, heap leach SX/EW mine plan centered on oxide copper ore and incorporating material from the Strong & Harris satellite deposit. The operation is expected to place 541 million tons on the leach pad over 21 years, with average annual production of 174 million pounds of copper cathode in the first 15 years, totaling 3.2 billion pounds over the mine life.
The updated study reports an after-tax NPV8 of about US$2.0 billion, a 22.7% internal rate of return, and a 3.9-year payback at a US$4.60 per pound copper price, with all-in sustaining cash costs of US$2.06 per pound placing the project in the lower half of the global cost curve. Operational enhancements, including the addition of the high-grade Strong & Harris deposit, material sorting, and a new cement co-product from high-purity limestone overburden, account for most of the NPV increase since 2024 and are expected to boost project economics while delivering substantial jobs, tax revenues, and economic output for Cochise County, Arizona, and the broader U.S. economy.
The most recent analyst rating on (TSE:GCU) stock is a Hold with a C$0.66 price target. To see the full list of analyst forecasts on Excelsior Mining stock, see the TSE:GCU Stock Forecast page.
Spark’s Take on TSE:GCU Stock
According to Spark, TipRanks’ AI Analyst, TSE:GCU is a Neutral.
The score is held down primarily by poor financial health (negative margins, negative equity, and worsening negative free cash flow). Technicals provide some offset with strong upward trend and positive MACD, but overbought indicators raise near-term risk, while valuation (P/E 27.66 and no dividend yield provided) offers limited support given the fundamentals.
