Miramar launches SAM survey to target bedrock gold source at Gidji

• Survey will target source of gold at Gidji with high-resolution sub-audio magnetic mapping technology
• M2R plans to map the mineralised bedrock structures beneath the paleochannel
• Source of supergene source could have multiple origins

Special Report: Having encountered a substantial amount of supergene gold at the Gidji joint venture project, Miramar Resources is launching a sub-audio magnetic survey in a bid to find the source.

The SAM survey will target the bedrock source or sources of the gold mineralisation, providing data to help map out the mineralised bedrock structures under the Gidji Paleochannel.

Miramar Resources (ASX:M2R) executive chair Allan Kelly believes the gold could have multiple bedrock sources nearby.

“The aircore drilling completed at Gidji has outlined a substantial amount of supergene gold mineralisation within the stripped weathering profile under the Gidji Paleochannel,” he said.

“We also know from regional studies of gold deposits along the Boorara and Bardoc shear zones, that the mineralised structures within those deposits are usually offset to that of the main shear zone.

“The results of the SAM survey, combined with our existing drilling data, will be used to identify key bedrock structures and assist in refining targets for deeper drill testing.”

Gidji JV gold project

Miramar holds an 80% stake in the Gidji JV gold project, which is about 15km north of Kalgoorlie-Boulder.

The project is surrounded by gold mining and processing operations but remained underexplored until recently due to extensive shallow transported cover and the Gidji Paleochannel which crosscuts the most prospective basement geology.

Miramar believes there is potential for a new gold camp at Gidji, with multiple gold deposits within the project area.

M2R selected a SAM survey for the next step of exploration as it produces high-resolution images of conductive structures in the regolith and bedrock that are useful for mineral exploration at prospect scale.

Unlike a traditional magnetic survey, which maps structures using the earth’s magnetic field, SAM creates an artificial magnetic field that can be oriented to preferentially target structures in one or more directions.

In this case, it’s targeted at the geology below the Gidji Paleochannel, which could host the source of the supergene gold on the project.
