BOTTLE CREEK GOLD MINE
Bottle Creek Gold Mine is located on the northern extremity of the Mt Ida-Ularring greenstone belt extending from Davyhurst to Mt Alexander (see Figure 1 in link below). The Ularring greenstone belt forms the western part of the Norseman-Wiluna Province of the Yilgarn Craton. The location of major ore zones within the mining leases, and local geology, is shown Figure 2 (see link below). Locally, gold and silver mineralisation is hosted in carbonaceous, sulphidic shales, within a larger package of interbedded basaltic volcanics, sediments and ultramafic rocks. The area is tightly folded and metamorphosed, with intrusion of younger dolerite dykes. Mineralisation at Bottle Creek occurs over a strike length of 7km, running north-west south-east and is interpreted to be nearly vertical, to steeply west-dipping.
Bottle Creek also hosts several zones of Au-bearing ferruginous laterite. The laterite has a variable thickness, up to 8m thick in some locations, and has been identified over several zones at Bottle Creek. Gold grades in the Bottle Creek laterite range from 0.02 up to 11.14 g/t Au.
Bottle Creek was discovered by Electrolytic Zinc Company of Australasia (EZ) in 1983, subsequently entered into a in Joint Venture with Norgold Limited who managed the project to mine stage. Ore was treated onsite in a CIP Circuit, producing 90,000 oz Au over an 18 month period from 1988-1989 from two open pits (see Image 1 in link below).
Significant drilling was undertaken by EZ and later by Norgold along a 9.8 km strike length from 1984 to 1989. RC drill fences at 100m spacing were carried out, with infill drill line spacing at 50m and 25m at various locations. Drilling was nominally to a depth of 80m vertical below surface. Subsequent to mining activities, Rio Tinto acquired Norgold, and carried out all required rehabilitation of the site. Therefore all mine rehabilitation conditions relating to the project were deleted from the schedule of conditions attached to the mining leases (see Note below).
Alt Resources considers Bottle Creek to be a standalone project with potential to develop a mineable resource. The project comprises two granted mining leases, existing tailings dams. Governmental approvals are also in place (application by the Vendor) for a new tailings dam and a test heap leach pad to process the existing low-grade ore stockpile onsite from the previous mining undertaken by Norgold.
Alt Resources has engaged BM Geological Services (BMGS) to conduct a review of the Bottle Creek drilling data and develop a JORC compliant resource as part of its due diligence process. Details of this review will be released to the market in the coming weeks.
The Company has provided BMGS with an access database consisting of open file data obtained from the Department of Mines, Industry Regulation and Safety's (Department) online WAMEX exploration report portal. Exploration results were obtained from reports A16161 dated 1984-85, A18217 dated 1985-86, A20156 dated 1986-87, A21207 dated 1986-87, A24964 dated 1987-88 and A28505 dated 1988-89 including exploration drilling results from:
- 5,071m in 78 Diamond drillholes;
- 43,492m in 839 Reverse Circulation drillholes; and
- 32,093m in 776 Rotary Air Blast drillholes.
Evaluation of the historical data is currently being undertaken by BMGS with support from the Company, and it is estimated that the Company will be in a position to provide details of the evaluation and report to the market by the end of November 2017.
In meeting the terms of the Agreement, the Company must undertake a minimum of 8,000 m of reverse circulation (RC) drilling at the project within 12 months which must commence no later than 15 March 2018. Alt Resources will focus initial drilling programs on the Emu and Southwark ore bodies located along strike from the mined VB pit (see Figure 3 in link below). Historical drilling results from EZ and Norgold Ltd open file reports are very encouraging and the Company expects to present the first results from confirmation and infill drilling in late April 2018.
The Company has recently acquired a high resolution airborne magnetic survey data set from Southern Geoscience and is currently undertaking a review of the mag data at the Bottle Creek project and surrounding area to enhance drill targeting for future work and will provide details to the market in the coming weeks.
Alt Resources CEO James Anderson commented on the Bottle Creek acquisition;
"We have been looking for a quality WA gold project for some time now and Bottle Creek is a classic example of a dormant asset that has been sitting for a long time. It was a reasonably high grade open pit mine in the late 1980's with a significant amount of drilling having been done. With the volume of historical drilling that has been conducted at the project, the existing knowledge base is considerable and presents a well-defined and valuable asset. Our strategy is to develop a JORC compliant resource at Bottle Creek by validating the historical drilling and conducting infill and extension drilling. We aim to confirm the resource base and undertake a scoping study for mine production once complete. The historical mining activities have given us excellent reported information on the mining, metallurgy and the plant design which will guide us in our next steps at Bottle Creek."
