Miramar Resources grows Marleybone prospect’s footprint during aircore exploration

Miramar Resources Ltd (ASX:M2R) has increased the footprint of a high priority prospect within its 80%-owned Gidji Joint Venture Project in WA’s Eastern Goldfields. A phase three aircore campaign recently took place at the Marleybone prospect to better define its gold prospectivity, with further aircore and reverse circulation (RC) drilling planned on the back of today’s results. Promisingly, multiple assays have since returned more than 1 g/t gold, increasing the propsect’s strike length to almost 2 kilometres. Beyond this, Marleybone remains open along strike to the northwest and southeast within Miramar’s existing tenement applications, virtually untested at depth below 60 metres. Drilling continues to grow Marleybone Miramar executive chairman Allan Kelly said: “Our systematic aircore drilling continues to grow Marylebone, with the footprint now stretching over almost 2 kilometres and the tenor of the results apparently increasing towards the northwest. “The new results are associated with northwest-trending mafic and/or ultramafic units within the Boorara Shear Zone crosscut by north–south trending structures, which is similar to that seen at Paddington. “The significant gold results occur at the top of weathered mafic/ultramafic basement rocks and are associated with anomalous silver, indicating a probable association with bedrock gold mineralisation.” Aircore results During the aircore campaign, multiple holes returned 4-metre composite samples with more than 1 g/t gold, extending the Marleybone target around 800 metres to the northwest. Significant new results include: 3 metres at 1.00 g/t gold from 52 metres to end of hole; 4 metres at 1.22 g/t from 48 metres; 4 metres at 1.46 g/t from 40 metres; 4 metres at 1.47 g/t from 44 metres; 4 metres at 1.02 g/t from 52 metres; 4 metres at 1.40 g/t from 52 metres; and 4 metres at 1.33 g/t from 52m= metres. The Gidji Project is located 15 kilometres north of Kalgoorlie and, despite being surrounded by several existing gold mining and/or processing facilities, has seen limited bedrock testing and minimal historical drilling over 100 metres. The Marylebone prospect is currently the largest and highest priority of four targets outlined by Miramar since it began exploration at Gidji in December 2020. It bears many similarities to the Paddington deposit, around 10 kilometres along strike to the northwest. Currently, Miramar is waiting on further assays from aircore holes completed on the eastern and southeastern margins of the Marleybone target. The ASX-lister plans to conduct additional aircore drilling to better define the prospect’s extent, with deeper reverse circulation exploration to follow. Initial RC campaign Recently, Miramar also conducted an initial, six-hole RC program at Gidjee to test beneath aircore results and gain information about Marleybone’s bedrock geology. The company has now received all results from this campaign, with single RC holes testing the Piccadilly and Railway targets and four holes testing the Marylebone prospect. Kelly continued: “We took the opportunity to complete these initial six RC holes to have a look at the underlying geology for the first time and hoped we might be lucky in also locating bedrock gold mineralisation. “The three successful RC holes only tested a small portion of the Marylebone prospect and we were unsure about the dip of the most prospective geology and/or structures, so it is probable some of the holes were not drilled with an optimal azimuth. “Given the latest aircore results, which have substantially grown the size of the Marylebone prospect, we remain very excited about the opportunity for a new gold discovery at Gidji."
