The Acra Project covers an area of 370 km² and is located 60 km north east of Kalgoorlie, WA. The Acra Project has a 20 km long, north-west trending, structural corridor, which is evident in aeromagnetic data with elements observable in field mapping, and which is considered prospective for gold. Physical gold has been recovered from small gold workings that date from the 1890s until WW2, and more recently from nugget patches that are still being located and worked. Most exploration undertaken from the early 1970s to the present, however, has focussed on identifying nickel mineralisation. Recently, an aeromagnetic survey over a large area of the Eastern Goldfields of Western Australia, including over the Company's Acra Project, was undertaken, with flight lines at 100m line spacing. This is a great improvement on the previously available data. The Company engaged Dr David Isles (Southern Geoscience Consultants) to generate gold targets within an area of 2,200 km², including the Acra Gold Project, using the new aeromagnetic data. This highlighted 14 areas for further work. Three phases of drilling demonstrate that the Acra Gold Project is advancing: Aircore drilling geochemistry extends Kalpini South target by 60% - to 240m. Extension has coincident EM conductor (likely detecting pyrite-arsenopyrite sulphides – host to primary gold at Kalpini South); High grade gold (9m at 6.17g/t Au) intersected in RC drilling at Kalpini South demonstrates presence of a shallow, supergene gold deposit (see release to ASX 18 December 2015); Diamond drilling indicates that multiple gold-in-sulphide lodes are present; Aircore drilling generates new targets, highlighting potential for further gold discoveries, including: KPAC078: 21m at 1.0g/t Au, including 3m at 4.6g/t Au from 42m, at the Deep River Prospect. On 21 October 2016, Northern Star entered a Joint Venture for Pioneer's Acra Gold Project, to fast track exploration.
Juglah Dome Project (Gold and Base Metals)
The 100%-held Juglah Dome Gold Project covers an area of 157 km² and is located 57 km SW of Kalgoorlie, WA. Exploration in 2014 confirmed base metal targets. Pioneer’s recent exploration programs have focused on the 4 km long, Dingo Dam Prospect which is considered prospective for volcanogenic massive sulphide (“VMS”) silver lead-zinc mineralisation. The size and tenor of the anomaly is very encouraging and specific VMS-directed exploration programs will continue.
