First Development Resources plc (AIM: FDR) the UK based, Australian focused exploration company with mineral interests in Western Australia and Australia’s Northern Territory, provides an update on the Company’s Phase I Diamond Drill Programme at the Wallal project in Western Australia’s Paterson Province.
The Company is pleased to report the successful completion of what it believes is the most technically difficult phase of drillhole 1 which is targeting the Eastern Magnetic Bullseye anomaly (see Figure 1 & Figure 2). Using the mud rotary drilling technique, the drillhole has advanced through the Wallal Sandstone formation which is a major constituent of the sedimentary cover sequence. Although several technical challenges were encountered within the Wallal Sandstone, they were effectively mitigated by the expertise and collaborative efforts of the onsite drilling team and operational support provided by FDR’s drilling partner DDH1 Drilling Limited. The experience gained whilst drilling the hole will significantly benefit the Company.
Drilling operations have now transitioned to coring which is progressing well. The hole is now advancing towards the basement geology which is interpreted to host the magnetic bullseye target (Figure 2).
