VANCOUVER, March 4, 2013 /PRNewswire/ - MAX Resource Corp. (TSXV: MXR); (OTCBB: MXROF); (Frankfurt: M1D) has received the preliminary report by John Fox, P.Eng., Consulting Metallurgical Engineer of Laurion Consulting Inc. on the test work carried out on samples from it's wholly-owned Majuba Hill copper/silver project in Nevada by Inspectorate Exploration & Mining Services in Richmond, B.C.
A total of fourteen samples of assay sample reject material (crushed to 6 mesh) were received at Inspectorate and these were made into a single composite weighing 58 kg. A sub sample was taken for head analysis and indicated a grade of 0.62% Cu and 34.6 g/t Ag.
A series of bottle roll acid tests were carried out with sulphuric acid at pH 1.3 on material running 6 mesh and on material ground to 200 mesh. After 14 days of leaching the copper extraction was 81.1% and 84.6% respectively. These results indicate the potential for heap leaching copper in a relatively short leach cycle, with acid consumption modest at 25kg/t, which is in line with expectations.
Leach testing was also conducted with thiosulphate over a six hour period and 24 hour period. Leaching was carried out at pH8 on the two samples, 6 mesh (un-ground) and 200 mesh. Silver extraction of 73.4% was achieved on ground material, which was 30% higher than on un-ground material. Thiosulphate leaching is normally very rapid; the difference between ground and un-ground leach recoveries may disappear over a longer leach cycle. Moreover, the silver leach value has not been optimized and it is expected that silver recovery may increase with longer leach times.
While cyanide leaching of sulfuric acid leach residue was also undertaken and gave about a 70% recovery, the thiosulphate leach route may be preferred because of reduced reagent costs (less lime required to neutralize acid to pH8 rather than pH10, and less consumption of lixivient as thiosulphate is not consumed leaching excess copper) as well as for environmental considerations.
Clancy Wendt, VP Exploration of MAX, states: "We are extremely pleased by these preliminary results, which demonstrate the feasibility of utilizing low-cost heap leach mineral extraction technology at Majuba Hill. Test work is still ongoing with respect to longer term thiosulphate leaching, with a number of processing methods also being examined and tested, with a view to determining the optimum recovery system for Majuba Hill."
Drilling by MAX in 2011 and 2012 intercepted high-grade copper/silver supergene oxide mineralization over long intervals starting at surface, confirming that Majuba Hill is highly prospective for the development of a bulk-tonnage, open-pit deposit. Permitting is underway for a development drill program at Majuba Hill designed to define an initial NI 43-101 compliant inferred resourceestimate by the end of 2013.
Majuba Hill is the site of numerous past producing mines, with historic production reported of 12% copper (Mason Valley Copper, 1918) and silver grades up to 40 oz/t Ag. The Majuba Hill project encompasses 3,128 acres of surface and mineral rights that includes patented lode mining claims. The property is easily accessed via 23 miles of well-maintained dirt roads leading from U.S. Interstate 80, and lies 30 miles northwest of Coeur d'Alene's Rochester silver mine, which contains a NI 43-101 compliant Measured and Indicated Resource of 263.9 million tons grading 0.46 oz/ton Ag and 0.004 oz/ton Au. (The Coeur Technical Report on the Rochester Mine is available on SEDAR). For more detailed information on the Majuba Hill project, please visit our web site at www.maxresource.com.
