Copper Hill Survey Identifies Broad Bedrock Conductor with Double Peak Signature

Exploration Advances at Copper Hill

Surefire Resources NL (ASX:SRN) has taken a decisive step forward in its copper exploration program with the completion of a moving-loop electromagnetic (MLEM) survey at its 100% owned Copper Hill Project. Located just 3 kilometres from the company’s Yidby Gold Project, Copper Hill has been under scrutiny following anomalous copper and zinc soil geochemistry detected in 2024 and historical reports of copper sulphides, including native copper, from earlier drilling.

Significant Bedrock Conductor Discovered

The MLEM survey, conducted by Southern Geoscience Consultants using advanced high-sensitivity equipment, successfully identified a broad bedrock conductor exhibiting a double peak in the late time channel. This conductor is modelled as a steeply dipping, northeast-striking plate, consistent with the structural controls known in the area and coinciding with zones where native copper was previously intersected. Such conductors are often indicative of Volcanogenic Massive Sulphide (VMS) style mineralisation, a geological setting analogous to the prolific Golden Grove deposits.

Follow-up Surveys and Drilling Plans

While a limited fixed-loop time domain electromagnetic (FLTEM) survey was also conducted to provide additional clarity, it did not yield further resolution on the conductor’s characteristics. As a result, Surefire is considering larger and more detailed geophysical surveys, including resistivity mapping, to better delineate the target and identify chargeability anomalies that could indicate disseminated sulphide mineralisation.

These geophysical results will directly inform the next phase of drill targeting, aiming to confirm the presence and extent of copper sulphides within the anomalous geochemical corridor. Managing Director Paul Burton described the discovery as "very encouraging," highlighting the survey’s role as a first-pass proof of concept and expressing optimism about advancing the project.

Integrated Exploration Approach

Surefire’s approach integrates geophysical surveys with rock chip sampling, geological mapping, and historical data analysis to build a comprehensive understanding of the Copper Hill mineral system. The identification of a conductive bedrock feature within a known geochemical anomaly strengthens the case for potential economic mineralisation, though further work is required to confirm its nature and scale.

With the Copper Hill Project positioned near existing gold and base metal assets, these findings add momentum to Surefire’s broader exploration strategy in the region, potentially unlocking new value for shareholders as the company progresses towards drill testing.
