Kingston shares preliminary RC drilling results for Livingstone’s Find area (Australia)

Australian exploration company Kingston Resources Ltd (Kingston) has received its preliminary assay results for the first round of reconnaissance (RC) drilling in the Livingstone’s Find area. This air-core drilling programme, the first in the area for more than 20 years, was co-funded by the WA Government’s Exploration Incentive scheme.

According to Kingston, drilling has highlighted the potential of the main line of historic workings, with mineralisation defined over a strike length of 2.2 km and composite assay grades as high as 7.01g/t Au. Importantly, gold has been identified up to 850 m west of the historic shafts and the prospect remains open along strike, greatly increasing the possible size of the mineralised zone. Surface sampling by Kingston around the old workings in late 2016 returned individual assays of up to 75 g/t, further highlighting the high-grade potential of the area. This prospect area, which was previously known as Mt Seabrook 1 and 2, has been renamed Kingsley. Northwest of Kingsley a new area of gold mineralisation has been confirmed by drilling at the Dampier prospect. Dampier, first identified in auger sampling by Kingston, is now approximately 500 m long with mineralisation open along strike to the west and east.

Managing Director of Kingston, Andrew Corbett, commented: “These initial results are a great start to our exploration around Livingstone’s Find. It’s a big area with geochemical anomalies over 5 km of strike, so we have a lot more drill testing to do. Getting grades like this in our first round of air-core drilling is a fantastic start.”

“We’ll head back to site and resample all these anomalous composites as soon as possible, and we expect to be back there with an RC rig for the next round of drilling later in the year.”

152 air-core holes were drilled for a total of 5836 m during April and May, targeting geochemical anomalies generated from auger drilling in 2017. According to the company, holes were mainly drilled to blade refusal to test mineralisation in the weathered zone, with all 4 m composite samples assayed for gold plus a bottom-of-hole sample on each hole assayed for a 33-element suite of metals. 77 holes intersected grades in excess of 100 ppb Au, of which 18 holes intersected 0.5 g/t or more.

Holes were designed on a nominal pattern of 40 m hole spacing and 160 m line spacing, with drill lines oriented north-south. Drilling was designed to achieve a quick, first-pass test for primary mineralisation beneath the strongest soil anomaly areas. Several areas could not be effectively drilled due to hard outcrop and steep terrain, so the full Livingstone’s Find project area requires further testing with a more versatile rig.

Kingston intends to continue upgrading areas highlighted by this recent programme, using a track-mounted RC rig to infill and extend mineralised trends. The company will also continue to use air-core drilling to infill coverage at Kingsley and Dampier, and to extend coverage over anomalies not yet tested. Kingston personnel will return to site immediately to re-sample the anomalous 4 m composites in single metre samples for fire assay analysis in Perth. The company will announce results from the resampling once they have been received.
