Lawyers-Ranch is a gold-silver system with a meaningful silver component that enhances project economics, provides leverage to a strong silver market, and highlights our long-term value proposition for our shareholders. As we continue to advance Lawyers-Ranch through permitting and toward feasibility, this new name more accurately represents the scale, quality, and opportunity we are building.”
