An announcement from Sunstone Metals Limited ( (AU:STM) ) is now available.
Sunstone Metals has released a scoping study assessing the potential open-pit development of its Bramaderos Gold-Copper Project in Ecuador, describing it as a preliminary technical and economic evaluation prepared to industry-standard accuracy and based on an existing mineral resource estimate. The study underpins a production target where early mill feed comes entirely from Indicated Resources, but most life-of-mine output is Inferred, highlighting both the project’s potential and the low geological confidence attached to a large portion of the resource.
The company stresses that further exploration, evaluation and higher-level studies are needed before any ore reserves can be declared or a definitive economic case can be made, and cautions investors not to base decisions solely on the study’s outcomes. Sunstone also outlines that developing Bramaderos is expected to require about US$525 million in funding, likely through a mix of debt and equity or alternative value-realisation strategies, underscoring both the scale of the opportunity and the financing and execution risks for shareholders and other stakeholders.
The most recent analyst rating on (AU:STM) stock is a Buy with a A$2.10 price target. To see the full list of analyst forecasts on Sunstone Metals Limited stock, see the AU:STM Stock Forecast page.
