Bielsdown NSW
Bielsdown EL6388 – north of Dorrigo, NSW
* 100% owned by Anchor Resources
* An advanced antimony project with tungsten and gold credits
* Ten hole drilling program completed in August 2009 to expand the resource at depth and along strike
* 2009 JORC resource upgrade 880,000t at 2.0% Sb using a 0.5% Sb cutoff grade (contained metal 17,500t Sb) by SRK Consulting
* Further drilling planned in early 2010 to extend known mineralisation
* Assess metallurgy and quantify demonstrated gold and tungsten credits
* Study the feasibility for a commercial mining operation
In 2009, a combined program of reverse circulation and diamond drilling successfully tested extensions to the shear/vein-hosted antimony mineralisation, both down dip and along strike, that were identified during the 2007 resource modeling and evaluation process. Anchor geologists have interpreted the mineralisation to have a shallow westerly plunge.
The initial program consisted of five holes designed to provide confidence in the existing resource geology and geochemistry, and more importantly, to test extensions of the mineralisation. Following the exceptional early results from the initial holes, the program was expanded to 10 holes. Holes consisted of a combination of reverse circulation pre-collars with diamond drillhole tails through the zone of mineralisation. Approximately 1800m of drilling was completed in these ten holes.
Background
The antimony focus has returned to the New England region (NSW) over recent years as Straits Resources commenced development of its Hillgrove underground antimony-gold mine late in 2008.
Anchor holds 100% of the Bielsdown Project (EL 6388), located 40km west of Coffs Harbour, which includes the old Wild Cattle Creek antimony mine. First production from the mine was in the late 1800s, with mining and exploration undertaken intermittently since that time. Historically, drill testing has been carried out in two phases, firstly during the 1960s (Dundee), with further drilling in the mid 1990s (Allegiance).
In early 2007, Anchor completed a compilation of historical exploration data to provide a resource estimate compliant with guidelines as setout in the JORC Code (2004) for the Wild Cattle Creek antimony (Sb) deposit. The study estimated a combined Inferred and Indicated resource, using a 1.0% Sb cutoff, of 459,000t at 3.0% Sb (13,900t contained Sb metal) contained primarily within the first 100m below surface:
Following Anchor’s successful drilling program of 2009, the resource was expanded to 880,000t at 2.0% Sb (17,500t contained Sb metal), using a 0.5% Sb cutoff grade. This resource was categorised by SRK Consulting as Inferred using guidelines as setout in the JORC Code (2004).
A drilling program has been proposed for early 2010 to further expand this antimony resource both down dip and along strike, as well as confirming historical drilling results.
Antimony Price
Anchor’s belief in the long term prospects for the antimony market is supported by robust global antimony prices. While demand and prices for base metals plummeted in 2H08, antimony prices remained relatively resilient finishing 2008 at US$5842/t compared to US$5886/t at end 2007. Although antimony prices weakened in the beginning of 2009, prices rebounded well during the year and are now above longer term averages. The graph below shows the price history for antimony over recent years.
What is antimony?
Stibnite (Sb2S3) is the main ore mineral of the element antimony (Sb). Antimony ores are beneficiated and processed into antimony metal or oxide. Antimony mine production is concentrated very heavily in China (91% of world output in 2008 – USGS). Antimony is primarily used as an enhancer of flame retardants or a hardening and strengthening agent for lead and zinc alloys. These alloys are used in lead storage batteries, solder, sheet and pipe metal, bearings, castings, ammunition and pewter, particularly for use in wet-cell batteries.
