Drilling recommences is great news , back in March they stated “We are also preparing to mobilise drill rigs to site to target the Klondyke Shear at a depth of 500m to 600m below surface. Our geologists are very confident that the system will extend to this level and beyond, which could underpin a long-life mine given that our resource is only drilled to an average of 230m below surface.”
Exploration Update Drilling Recommences at the Warrawoona Gold Project HIGHLIGHTS • Drilling recommenced at Klondyke • Drilling at the recently acquired Otways Project planned for August 2020 • Aeromagnetic and radiometric data received and being processed Calidus Resources (ASX:CAI) is pleased to announce that it has commenced drilling at its flagship Warrawoona gold project in the Pilbara, following the opening of regional borders in Western Australia. The drilling at Klondyke will target the main Klondyke structure 300m directly below the existing Resource and is expected to be completed next month. Calidus will then drill a significant walk-up copper-gold target at its recently-acquired Otways Project, 50km from Warrawoona. Calidus Managing Director Dave Reeves commented: “Whilst we continue to accelerate Warrawoona towards development, we are concurrently building a pipeline of projects and growing our metal inventory in the area. Our initial drilling at Klondyke will target the Klondyke Shear 300m below the current resource base to test continuity of the structure with the aim of highlighting the underground potential of Klondyke beyond the current resource. We will then turn our attention to the Otways Project where we have an outstanding walk-up drill target to test initially. With parallel work streams, and as we close in on development of Klondyke, we anticipate strong news flow over the coming six months.”
Klondyke Drilling Calidus is planning to drill two holes, each with a wedge “daughter” hole drilled off it, beneath the centre of the Klondyke Resource to test the continuity of mineralisation at a depth of 300m below the existing 250m deep resource. RC precollars will be undertaken to a depth of 400m to 450m before swapping to diamond drilling. The programme is expected to take 2 months to complete and is designed to prove continuity of the Klondyke Structure as a long-term source of ore for the upcoming development.
Otways Project Drilling Calidus recently entered into a Heads of Agreement with Rugby Mining to earn up to 70% interest in the Otways Project NE of Nullagine1. In the late 1960s, shallow (<60m depth) percussion drilling of coincident soil and IP anomalies by Conwest identified copper mineralisation in metabasalts at or near surface2 (refer Figure Two). In addition, several holes contain Cu mineralisation that is open at depth. Historic drilling was never assayed for gold but nearby costean samples returned values of up to 13g/t Au3. Recent site visits identified the locations of previous drill holes and have confirmed visual occurrences of copper mineralisation at surface and in shallow workings. Calidus has applied for a POW to allow commencement of drilling at the Otways Project. Initially, a programme of 6 to 8 RC holes is planned to verify and extend at depth shallow intercepts in historic drilling at the Otways Project. One diamond drill hole is also planned to better define the structures hosting mineralisation and the style of mineralisation.
Aeromagnetic and Radiometric Survey at Warrawoona Calidus and its geophysics consultants, Southern Geoscience Consultants, have now received the aeromagnetic and radiometric data recently flown at 25m line spacing across the bulk of the Warrawoona Tenements by MAGSPEC (refer Figure Four). Processing and interpretation of the data have commenced. Once the interpretation is completed, initial targets will be followed up with fieldwork and sampling to allow the targets to be prioritised and potentially drill tested late this year.
