Recent early stage aircore drilling results substantially increase the footprint of the Marylebone prospect, part of Miramar’s 80% owned Gidji JV project in the Eastern Goldfields region of WA.

Gidji is 15km north of Kalgoorlie and, despite being surrounded by several existing gold mining and/or processing facilities, has seen limited bedrock testing and has minimal historic drilling below 100m.

Marylebone — the largest and highest priority of four targets outlined by Miramar Resources (ASX:M2R) since commencing exploration at Gidji in December 2020 — has many similarities to the Paddington deposit, ~10km along strike to the northwest.

New drilling results from Marylebone include multiple holes with 4m composite samples  greater than 1g/t gold.

These extend the Marylebone target by approximately 800m to the northwest for a total strike length of almost 2km.

The prospect remains open along strike to the northwest and southeast within Miramar’s existing tenement applications and is virtually untested at depth below about 60m.

Miramar exec chairman Allan Kelly says the company had not yet outlined the full extent of the Marylebone prospect.

“Our systematic aircore drilling continues to grow Marylebone, with the footprint now stretching over almost 2km and the tenor of the results apparently increasing towards the northwest,” Kelly says.

“The new results are associated with NW trending mafic and/or ultramafic units within the Boorara Shear Zone crosscut by N-S trending structures which is similar to that seen at Paddington.

“The significant gold results occur at the top of weathered mafic/ultramafic basement rocks and are associated with anomalous Ag, indicating a probable association with bedrock gold mineralisation.”

Miramar is waiting on results from further aircore holes recently completed including on the eastern and south-eastern margins of the Marylebone prospect.

The company plans to continue refining the extent of the Marylebone prospect with further aircore drilling followed by deeper RC drilling.
