Reverse circulation drilling is now underway to test Miramar’s conviction  its 80%-owned Gidji joint venture project has the potential to host a new gold camp with multiple discoveries.

The drill program, which is the first stage of its 2022 exploration campaign, will test below significant aircore results at the Marylebone prospect for the first time.

While results are currently pending for the recent Phase 5 aircore drilling, previous holes had returned results such as 6m grading 1.23 grams per tonne (g/t) gold at the northern end of the prospect.

RC Drilling will also be used to gather information about the local bedrock stratigraphy, which will enable comparisons with the geology of the 4Moz Paddington gold deposit to the north, which Miramar Resources (ASX:M2R) believes Marylebone is similar to.

“We know that other gold deposits along the Boorara Shear Zone, such as Paddington, are hosted in relatively brittle quartz-dolerite units in between softer ultramafic rocks and/or sediments,” executive chairman Allan Kelly said.

“The aircore drilling completed to date has focused us in on a 2km segment of the Boorara Shear Zone with multiple significant aircore results but has given us limited bedrock information due to the presence of the transported cover and stripped weathering profile.

“This RC drill program will test the most prospective part of Marylebone for the first time.”

Just the start at Gidji

The Marylebone RC drilling is expected to be followed by aircore drilling at the Blackfriars, Highway, Boorara North and Boorara South targets.

Highway is a 1km long gold anomaly identified from historical data that has not been directly tested by historical or recent drilling though work on its edges hints at its potential to host a significant gold deposit.

Miramar will also extend the detailed magnetic survey over the northern Boorara Shear Zone and will refine “The Jog” target for RC and/or diamond drill testing.
