Shares of Solstice Minerals Ltd (ASX:SLS) soared 18.18% during intraday trading on Monday, following a significant operational update from the company.

The surge was driven by the company's announcement that it found visible copper sulfide mineralization in multiple zones downhole during its diamond drilling at the Nanadie project in Western Australia. The discovery was reported in a filing with the Australian bourse, indicating a positive development in the company's exploration efforts.

The first diamond drillhole at the project was completed to a depth of 629 meters. Geological logging and core processing are currently underway, with assay results expected in approximately five to six weeks, according to the filing.
