Miramar Resources extends and upgrades Marylebone gold target strike length to 1.7 kilometres at Gidji JV

Miramar Resources Ltd (ASX:M2R) extended the Marylebone target strike length to 1.7 kilometres during recent phase-2 aircore drilling, which returned 4-metre composite assays between 0.25 g/t and 1 g/t gold at depths of 44 to 60 metres within the Gidji joint venture project in Western Australia. Marylebone is the highest priority of the four targets outlined by Miramar in the Phase-1 aircore drilling campaign completed in December 2020 that returned initial results up to 3 metres at 5.26 g/t gold. The Phase-2 aircore campaign was designed to infill the drill spacing to around 200 metres by 50 metres with many of the intersections lying beneath shallower paleochannel clay and sands, which would have rendered any previous historical drilling or geochemical sampling ineffective. This gold anomalism is associated with the Boorara Shear Zone, which is crosscut by a later north-south structure and remains open to the northwest along strike onto Miramar’s tenement applications awaiting grant. Potential to host “something significant” Executive chairman Allan Kelly said the new results reinforced the high prospectivity of the Gidji JV project. He said: “The consistency in the depth and tenor of the results, along with the footprint of the gold anomalism, are indications that the Marylebone target could host something significant at depth. “The local geology, structure and scale of the Marylebone target are remarkably similar to the 10-million-ounce Paddington gold deposit approximately 10 kilometres along strike to the north.  “We are therefore excitedly looking forward to the next step in exploration at Marylebone, which will include systematic bedrock testing of the target for the first time.” Upcoming work Miramar has begun planning further exploration work at Marylebone, which will include: Reverse circulation (RC) bedrock testing beneath significant aircore results; Extensional aircore drilling along strike to the northwest and in the northeast; Infill aircore drilling of wider spaced holes; Completion of a ground magnetic survey to help outline bedrock geology and structures; and Progressing the tenement applications to grant. Diamond drilling at 8 Mile Miamar has also received results for the first two diamond holes drilled at the 8-Mile target. Drill-hole GJDD002 intersected visible gold in a quartz/sulphide vein in the hanging wall sandstone above the Runway porphyry. The holes were designed to intersect the steep westerly dipping porphyry at a high angle. As a result, the shallow east-dipping quartz vein was intersected almost parallel to the core and returned a result of 1-metre at 2.79 g/t gold whilst presence of coarse gold and the small assay sample size resulted in strong variation in repeat assay results of 1.61 g/t gold and 5.73 g/t gold. This same vein was also intersected in GJDD001 and returned a result of 1-metre at 0.53 g/t gold from 106 metres. The Runway porphyry and the quartz sulphide breccia were only weakly mineralised and the top 100 metres and the footwall sediments were not assayed in either hole.
