Gold Resource: Three Sisters Is Working, The Rest Still Isn't

Gold Resource Corporation is a single-asset miner with all production from the Don David mine in Oaxaca, Mexico, exposing it to significant geographic and country risk. GORO operates at a structurally high AISC—$3,476/AuEq this quarter—about 65–75% above comparables, due to low production scale and fixed cost burden. While recent discoveries at Three Sisters offer higher silver grades, the projected decline in grades and limited reserve life highlight ongoing operational challenges.
