A strong focal point is the 100%-owned Warralong Gold Project in the Pilbara region, which is prospective for intrusion hosted gold in a ‘look-alike’ structural setting to recent discoveries in the district.
The project covers 50 kilometres of the Lalla Rookh shear zone and second-order structures, in an analogous setting to discoveries along the Tabba Tabba Shear Zone 50 kilometres to the west.
Sipa is advancing a reconnaissance aircore drilling program and has already completed 2,000 metres of the proposed 4,000-metre campaign.
During the drilling, Sipa has encountered a range of basement lithologies representative of several intrusive rock types, with occasional minor pyrite.
It plans to undertake comprehensive basement interpretation once drilling is complete and assays are received.
The company has completed drill holes on 100-200 metre spacings along lines above the targets generated from its earlier exercise and the thickness of cover material has been anticipated to range between 10 metres and 40 metres.
Basement has been intersected in all but one of the 65 holes drilled to date and it hopes to complete this first program in early September.
At the 100%-owned Wolfe Basin Project, Sipa has secured a diamond drill rig to test targets generated from a recent dipole-dipole induced polarisation (DDIP) survey over the Romulus prospect.
It is about to start the site preparation work to advance the drilling, which is planned to start in the fourth quarter of 2021.
Diamond drilling is preferred in this situation as abundant groundwater and fractured rock made it difficult to reach target depths using percussion drilling in previous reverse circulation drilling,
The DDIP survey shows a distinct, chargeable feature at approximately 150-200 metres below surface potentially due to sulphide mineralisation immediately to the east of the previous drilling.
The chargeable feature is also visible on the DDIP lines to the north and south of where drilling was completed.
Sipa’s first drill program intersected up to 2.9% lead and 0.5% copper with extensive areas remaining to be tested along more than 40 kilometres long prospective horizon.
Paterson North Project
The Paterson North Copper-Gold Project in which Sipa holds 89%, is being progressed in partnership with Rio Tinto Ltd through a farm-in arrangement.
An extensive gradient array induced polarisation (GAIP) geophysical survey has been 75% completed.
The company plans to combine results with the other geophysical data already collected to refine drill targets and potentially identify new targets prospective for copper-gold mineralisation.
Currently, Sipa is waiting for heritage approval for one specific area, which may be postponed until the 2022 field season but this is not expected to impact the drill targeting or drilling plans for 2022.
Barbwire Terrace JV
The Barbwire Terrace Project is in the Canning Basin of Western Australia, where Sipa is targeting MVT style lead-zinc deposits in collaboration with its 50:50 joint venture partner, Buru Energy Limited.
The company plans to start a gravity survey over existing target areas, which is likely to start soon to assist in refining drill hole locations.
Future drilling will be supported by a recently received Exploration Incentive Scheme (EIS) grant from the Western Australian Government.
