Miramar Resources Limited (ASX:M2R) has received further significant aircore drilling results from its 80%-owned Gidji JV Project in the Eastern Goldfields of Western Australia.
The company has now received all remaining results from the December 2021 aircore drilling campaign. The programme had previously delivered a number of significant new results from the Marylebone and Blackfriars targets, including some of the best results returned from the Project to date.
The final batch of assays included significant results from three holes, including GJAC619, which is located at the far northern end of Marylebone East and intersected 4m @ 1.54g/t Au. The Marylebone East target remains open to the northwest of this hole for at least another 500m giving a total strike length of approximately 2.5km.
Blackfriars/Highway aircore drilling
The aircore drilling at the Blackfriars target has identified an intermediate porphyritic unit between the Black Flag Beds, to the west, and the porphyritic basalt unit to the east. One of the key components of Miramar’s exploration model at Gidji is identifying competent rock units sandwiched between less competent units, where the more competent rocks can act as a focus for gold mineralisation which is then trapped and/or offset by later faults. This geological and structural relationship is observed elsewhere at several major gold deposits including Paddington and Mt Charlotte.
This newly recognised porphyry unit, observed in two drill sections so far, may be the equivalent of the porphyry that hosts the majority of gold mineralisation at the 1.6 million ounce Aphrodite gold deposit which is also located at the contact between Black Flag sediments and a basalt unit. The current aircore drill programme is infilling the Blackfriars footprint and testing the Highway target for the first time.
Executive Chairman, Allan Kelly, said the most recent drill results, along with geological observations from the current drilling programme, underscored the huge potential of the Gidji JV Project.
“At Gidji, we now have analogues for not one, but two plus million-ounce gold deposits,” Mr Kelly said.
“The Blackfriars target seems to have the same geology and scale as the 1.6 million ounce Aphrodite deposit but, to date, we have only tested it with very wide-spaced aircore drilling,” he added.
“Given the size and tenor of the untested historical auger Au-As anomalism at Highway, we are hoping we might have a trifecta at Gidji,” he said.
