Redcastle Resources Ltd (ASX:RC1) has revealed that siteworks have commenced on the drill pads for its upcoming 1,275m RC drilling programme on its namesake project in Western Australia.
The company has secured a suitable RC drill rig, and this is scheduled to mobilise to site by the end of this week.
RC drilling is anticipated to commence early next week. In addition, an auger contractor has been secured and this crew will mobilise to site within approximately three weeks to carry out the wider soil sampling programme.
Following a review of the available geological data relating to the central area which contains the bulk of the historic workings, a circa 1200m RC drilling programme was planned by the company’s consultants.
The aim is to:
- Validate and confirm several generations of historical drilling results
- Confirm the geology, orientation and continuity of the known gold mineralisation
- Obtain further details regarding the extent of the historic underground workings in the area
- Collect preliminary geotechnical data The digital database currently includes collar and assay data.
The raw collar elevation data has been modified slightly via the completion of a digital terrain model (DTM).
This DTM was constructed from the very detailed low level aeromagnetic survey completed by a previous explorer in about 2007-8. Other geological data (oxidation, rock type, quartz veining, etc) from the limited amount of previous drilling is being entered into the database. This area has seen previous shallow RC and RAB drilling.
Maximum depths in this area are approximately 50m vertical. There are only preliminary surveys available from the shallow underground workings.
These are also being digitised from the existing mapping. One of the aims of the drilling programme is to confirm some of these details. In relation to the upcoming drill programme, a drill spacing of ten metres was selected on sections 40m apart.
The holes range from 25m to 120m, an expected typical open pit depth. 18 holes for 1,275m are proposed. All proposed holes will be drilled at 60 degrees towards north.
