Eastern Goldfields Projects

Miramar has three underexplored gold projects near Kalgoorlie in Western Australia – Gidji JV, Glandore and Randalls. All have excellent access and are well positioned in relation to existing mining and processing operations.

Gidji JV (80%)

The Gidji JV Project is located within the Eastern Goldfields approximately 14km north of Kalgoorlie. Miramar purchased an 80% interest in the Project as part of the 2020 IPO.
The Project has a number of tenements located along a major structure, the Boorara Shear, which hosts gold mineralisation at Paddington approximately 10km along strike to the north.
The project has been well covered by historic drilling and auger sampling, but most holes are less than 60m deep. A significant dilational jog is seen in the Boorara Shear within the project tenements which has been poorly tested with drilling.

Gold mineralisation has been discovered within an intrusive unit immediately south of the Project, at the “8-mile Dam” prospect owned by KCGM. KCGM defined a “mineral inventory” of approximately 314,000 ounces within the “Runway” deposit which was used to support an application for a Mining Lease which abuts the Gidji JV Project’s southern boundary. The oxide and primary mineralisation potentially continues to the northwest, onto the Gidji JV Project tenements, but has been poorly explored despite an aircore anomaly stretching north for a further 1.8km.

A number of targets have been identified for drill testing following listing including:
  • The potential northern extension of the Runway deposit
  • The obvious dilational jog within the Boorara Shear
  • Numerous other shallow Aircore and RC drill intersections that have not been effectively followed up

Glandore

The Glandore Project is located within the eastern Goldfields, approximately 40km east of Kalgoorlie, Western Australia. The Project covers approximately 42 square km and consists of 10 Prospecting Licences and one Exploration Licence, all of which are granted.

Miramar purchased 100% of the Project as part of the 2020 IPO.

The highest priority western part of the project is underlain by a layered mafic sill intruding into basalt and sedimentary rocks. The dolerite sill comprises various varieties of dolerite and gabbro analogous to the Golden Mile Dolerite.

The local geology has been folded into a north-plunging antiform with the Project located on the eastern limb, southeast of the hinge zone. The antiform has been intruded by a granodiorite and felsic porphyry dykes.

The prospective geology is overlain by up to 50m of recent playa lake sediments which thin towards the west.

Exploration has been mostly limited to the western part of the project, within the Prospecting licences, and has been sporadic since the late 1980’s.

Drilling has identified mineralisation over approximately 2.5km of strike within the folded mafic package, associated with quartz-pyrite veins and ankerite-sericite-pyrite alteration.

Randalls

The Randalls project is located immediately east of Silver Lake Resources Limited’s Maxwell’s and Cockeyed Bob gold mines, approximately 70km east of Kalgoorlie (Figure 10). The project consists of a single Exploration Licence Application.

The project covers extensions to the folded Banded Iron Formation (BIF) and sediments that host the gold mineralisation currently being mined by Silver Lake.

Soil sampling followed by aircore drilling has proven to be an effective exploration technique in this area and will be used to define further targets.
