Multiple high-grade gold hits from aircore drilling completed in December 2021, have extended the strike of Miramar’s Marylebone prospect to over 2km.

Results such as 1m grading 11.8 grams per tonne (g/t) gold and 1m at 11g/t gold have really lent support to the company’s belief that there is potential to discover at least one if not more significant deposits within the strategic 60km land package that makes up its 80%-owned Gidji joint venture project just 15km north of Kalgoorlie.

Miramar Resources (ASX:M2R) adds that the new high-grade results on the eastern Marylebone trend are located between two earlier 200m-spaced lines with single holes which returned intersections of 1m at 3.62g/t gold and 1m at 2.65g/t gold respectively.

This trend also includes multiple +2g/t gold hits over a total strike length of at least 2.2km with hole GJAC627, at the northern end of the Blackfriars target, ending in 1m @ 11.80g/t Au in black shale.

This intersection is open to the north, east and at depth and will be followed up as part of the current aircore drilling programme which started on 7 April.

“Gidji is in a fantastic location, with the right geology and structures, and a growing supergene gold footprint that indicates the potential for a significant bedrock gold source nearby,” executive chairman Allan Kelly said.

“Each aircore programme we have completed at Gidji since listing has improved on the previous results and provided a better understanding of the Project, and this programme is no exception with multiple new high-grade gold results from Marylebone and our new Blackfriars target.

“The Gidji Project provides Miramar with a unique greenfields gold discovery opportunity right on the doorstep of the richest patch of ground on earth, and we therefore look forward to continuing to uncover the huge potential opportunity at Gidji with systematic and methodical exploration.”

Further exploration

The current aircore drill program will infill the Blackfriars target to a drill spacing of 200m by 50m while testing the Highway target for the first time.

Blackfriars target is located at the contact between the Black Flag Beds and a porphyritic basalt unit, in a similar geological setting to the Aphrodite and Lily Albany deposits further north along strike.

Miramar has also commissioned a detailed UAV magnetic survey over the Boorara North target and is currently in the process of obtaining heritage approvals which will allow for first pass aircore drill testing of this highly prospective gold and/or nickel target.

This 4km long segment of the Boorara Shear Zone, which is mostly covered by lakes and associated surficial deposits, has been poorly tested with shallow drilling.

It follows a UAV magnetic survey over the southern portion of the project – where the pervasive blanket of transported material makes ground magnetic survey data susceptible to near-surface features – which provides a more complete data set compared with both the regional magnetic data and the ground magnetic survey data.
