Miramar Resources Ltd (ASX:M2R) will be busy in the lead-up to the Christmas-New Year period as it forges ahead with a 10,000-metre aircore drilling program at the 80%-owned Gidji JV Project in the Eastern Goldfields region of WA.
As well as infilling existing drilling over the Marylebone target, the aircore program that began this week will test for potential extensions on recently granted tenements to the northwest.
Refining target
Miramar’s executive chairman Allan Kelly said the aim of the current drilling was to help refine the Marylebone target before bedrock drill testing in the new year.
“Marylebone continues to grow with each drilling campaign, with the most significant results coming from the north-western end of the target which currently remains open,” he said.
“We, therefore, want to make sure we fully understand the size of the target when we commit to RC and/or diamond drilling in the new year.”
Miramar expects to complete the extensive program before the Christmas-New Year break.
Gidji JV Project is within the Eastern Goldfields, around 15 kilometres north of Kalgoorlie. Miramar purchased 80% of the project tenements as part of the 2020 IPO.
The project contains about 15 kilometres of strike of a major mineralised structure, the Boorara Shear Zone, which hosts a number of significant deposits elsewhere along strike, including the Paddington and Boorara deposits.
Ground magnetic survey
Miramar’s aircore drilling coincides with ground magnetic survey work aimed at refining the geology and structure.
The company recently commissioned an extension to the previous ground magnetic survey over Marylebone, including on recently granted tenements to the northwest and southeast.
New data has highlighted and helped refine the basement geology and structures within the Boorara Shear Zone to the northwest of the Marylebone target where the aircore drilling is taking place.
The survey also covered an area of subdued magnetics southeast of Marylebone, over 'The Jog' target, and highlighted a surficial feature interpreted to represent a shallow channel filled with maghemite.
Survey extension
Further ground magnetic surveys will be conducted over the northern part of the Gidji JV Project focusing on a 4-kilometre-long underexplored segment of the Boorara Shear Zone.
Miramar believes the Gidgi project has been significantly under-explored despite its location within this major mineralised structure and proximity to several existing and historical gold mining and processing operations.
Since listing in October 2020, the company has conducted systematic exploration over Gidji resulting in the highlighting of several new targets including the potential for a large new gold discovery at Marylebone.
