Paramount Gold Nevada Corporation (New York Stock Exchange: PZGIt said it has initiated an SEC-supervised SK 1300 Initial Appraisal (IA) for the 100% owned Sleeper Gold Project, a previously producing high-grade gold mine located in Humboldt County, Northern Nevada.
The implementation evaluation will be prepared in accordance with applicable US regulatory standards and will evaluate the economic potential of the project.
The assessment aims to examine a potentially less costly phased development approach focusing on leachable materials only, including approximately 54 million tons of economically important materials. This includes surface materials from previously unassessed landfills, as well as oxide and mixed in situ mineralization that are amenable to heap leachability. This approach has the potential to support an accelerated trajectory of cash flow and enhance overall project economics, based on previous evaluations that focused primarily on on-site resources. He is also expected to contribute to development planning and evaluate potential future expansion opportunities.
Paramount CEO Rachel Goldman said: “Following our internal review, we believe that material historical data supports the initial divestment-only evaluation at Slipper, and we are now progressing in evaluating development options. Slipper is a large pre-producing asset in an established mining district with existing infrastructure, and in the current gold price environment, we see a compelling opportunity to unlock value. Focusing on oxidants and transitions is a logical first step to identify the project’s development potential and guide the next phase of the business.”
“At the same time, we continue to advance our Grassy Mountain project through final permitting and feasibility activities, positioning the company for two important projects moving forward.”
Paramount engaged SLR International Corporation (SLR) to conduct the study. SLR is currently active on site with its ongoing monitoring and reclamation programs and will leverage its recent acquisition of Forte Dynamics to incorporate improved leach kinetics expertise into the evaluation. An SLR is a qualified person within the meaning of Subpart 1300 of Regulation SK.
In parallel, the Company plans to begin permitting sub-drilling targeting surface materials at Slipper, which may support future resource upgrades and contribute to pre-feasibility or post-feasibility studies. It is expected that the issuance of permits will be straightforward and timely, as the proposed activities fall within the scope of the current operations plan.
The initial evaluation is expected to be completed in late Q2 2026, marking a major milestone in the company’s evaluation of development options at Sleeper.
Paramount Gold Nevada is a US-focused exploration and development company developing a portfolio of high-grade gold projects. The company has a 100% interest in approximately 50,000 acres across three projects: Grassy Mountain, Sleeper, and Bald Peak.
Grassy Mountain is an advanced development in Malheur County, Oregon. Sleeper is a pre-production, early-stage development project in Humboldt County in northern Nevada, one of the world’s leading mining regions, with a large, highly prospective landfill. Bald Peak is an early-stage exploration project in Mineral County, Nevada.
