Ecuadorian gold and copper explorer Sunstone Metals has initiated a $10 million capital raise, engaging a syndicate of four brokers to secure funding for its exploration activities.

The move represents a significant injection of capital for the ASX-listed company, which currently holds a market capitalization of approximately $47 million.

The broker syndicate includes RBC Capital Markets, Morgans Corporate, Foster Stockbroking, and Shaw and Partners.

Bids for the raise were due by 4pm on Thursday, indicating a tight timeline for securing investor commitments.

This level of institutional involvement suggests the company is targeting a broad base of investors to support its near-term operational needs.

Sunstone Metals is focused on developing its assets in Ecuador, a jurisdiction that has seen fluctuating investor sentiment due to regulatory and political dynamics.
