Nova Minerals Ltd (ASX:NVA, NASDAQ:NVA, OTC:NVAAF) has delivered strong metallurgical results from its RPM gold deposit, part of the Estelle Gold and Critical Metals Project in Alaska — boosting the project's production potential.
In its latest pre-feasibility work, Nova achieved gold recoveries of up to 68.7% using heap leaching — which is a cost-effective method ideal for processing low-grade ore.
A standout result came from the ore sorting program. Nova upgraded material from 1.32 grams per tonne to 5.72 grams — in a single pass. That’s more than a fourfold increase in grade, which could significantly cut waste and energy use while improving feed quality.
Nova is also progressing carbon in pulp/carbon in leach studies and high-pressure grinding tests to further boost recovery and reduce power costs.
These results reinforce Estelle’s potential to become a major long-life gold district in North America — with pre-feasibility work now well underway.
