Mt Roberts Drilling to Commence
Canberra, Oct 20, 2016 AEST (ABN Newswire) - Alt Resources Ltd (
ASX:ARS) ("Alt or the Company") is pleased to announce that drilling will commence on the 31st October at the highly prospective Mt Roberts-Cottee gold project, near Leinster, WA (see Figure 1 in the link below). 29 RC holes have been planned, for a total of 1,800m. A Plan of Works has been approved by the West Australian Department of Mines and Petroleum.
Key Points:
- Drilling will commence 31 October at the Mount Roberts-Cottee Project near Leinster, WA
- 1,800m Reverse Circulation drilling planned, for 29 drillholes
- Drillholes to target mineralisation beneath historical workings and confirm high grade historical intercepts
- First pass drilling also planned to test significant soil anomaly along strike from Mt Roberts to the south
Alt announced on the 30th August, 2016 that it had reached an agreement with Mount Roberts Mining Pty Ltd (MRM) to farm into the Mt Roberts-Cottee project (refer to the following link). Under the agreement, Alt can earn up to an 80 % interest in the Mount Roberts Mining Project in stages by funding drilling and exploration activities, and making a cash payment. The Mount Roberts-Cottee project includes the mining leases M36/341 and M36/279, covering a total of 2.41 km2 of prospective ground.

Significant intercepts from historical drilling by Consolidated Gold Mines Ltd in 1998 are given in Table 1 (see the link below). The quality of the Consolidated Gold Mines data cannot be verified (see JORC Table 1 in the link below). Results include:
- RB8: 2m @ 1.5 g/t Au from 26m
- RB8: 1m @ 1.67 g/t Au from 34m
- RB8: 10m @ 3.3 g/t Au from 46m
-- including 2m @ 7.8 g/t Au from 49m
-- hole ended in mineralisation
- RB11: 8m @ 2.77 g/t Au from 24m
-- including 1m @ 7.2 g/t Au from 25m
-- and 1m @ 6.5 g/t Au from 30m
- RC2: 4m @ 3.0 g/t Au from 38m
-- including 1m @ 3.8 g/t Au from 38m
-- and 1m @ 7.6 g/t Au from 41m
- RC6: 7m @ 1.3 g/t Au from 51m
-- including 1m @ 4.9 g/t Au from 56m
- RC9: 1m @ 1.43 g/t Au from 28m
Mount Roberts-Cottee Project
The Mount Roberts-Cottee Project is located 9 km northwest of Leinster (see Figure 1 in the link below) and 19 km northeast of the 3.8 Moz Agnew Gold Mine (Gold Fields Ltd). The project lies within the Agnew-Wiluna Greenstone belt, which is host to several major gold deposits including the Agnew Gold Mine, Lawlers and Vivien, within or near the Agnew Gold Camp.
The project area is characterised by a tightly folded sequence of altered komatiites, basalts, felsic volcanics, and fine sediments (see Figure 2 in the link below). Mount Roberts-Cottee is located on the eastern limb of the Mt White Syncline and the western limb of the Leinster Anticline. Major NNW-striking shears are located to the east and west with secondary mineralised splays occurring within the licence area.
Gold mineralisation occurs on the sheared contact between the ultramafic and mafic units. It forms a west dipping lens associated stacked quartz veining. Mineralisation has been intersected in historical drilling along a 200m strike length but remains open to the north and south.
Rotary Air Blast (RAB) and Reverse Circulation (RC) drilling was conducted in 1998 by Consolidated Gold Mines Ltd targeting the sheared contact between the komatiite and basalt units. Most holes were angled to the west, along a west-dipping contact and thus may have missed the most significant zones of gold mineralisation. Significant intercepts are given below in Table 1 (see the link below).
Planned drilling by Alt Resources will be primarily focussed on improving the density and level of confidence in historical drilling at the main zone of mineralisation at Mt Roberts-Cottee. This will include twinning some historical holes as well as performing infill drilling between sections. First pass drilling will also be undertaken as one line of holes across the untested soil anomaly described above in Figure 2 (see the link below).
Reported intercepts are downhole widths. The true width of the mineralised structure is not known. The data reported above in Table 1 (see the link below) is from historical reports submitted to the Geological Survey of WA in 1998 by Consolidated Gold Mines Ltd, based on RC and RAB drilling that they performed. No Quality Assurance/Quality Control data is available to verify the quality of the reported data. Where specific sampling techniques are known from historical reports, they are described below in the JORC Table 1 (see the link below). Alt Resources will perform a number of check holes during planned drilling, to validate these historical results.
Consolidated Gold Mines Ltd also undertook detailed soil sampling, and identified a strong gold anomaly (up to 180 ppb) over 700m along strike to the south from known mineralisation (see Figure 2 in the link below). No follow up drilling or detailed exploration has been undertaken since this time, leaving the Project largely under-explored. In particular, the soil anomaly in the south of the project represents an immediate drill target for Alt Resources.
Alt plans to undertake an RC drilling program at the Mount Roberts-Cottee project to confirm a number of previous high grade intercepts, fill in the existing drill spacing ahead of resource modelling and target extensions to mineralisation particularly along strike to the south. The aim of this drilling program will be to expand the known deposit and produce a JORC (2012) compliant resource.
