Mike, Strange that you mention Manganese, because that was my intuition. I will be sending you a sample, but please be kind in your billing, because I am poor and your are a big expensive gun in this industry. How about the super long term bargain analysis. This is no big deposit, but I am interested to know what it is. Jack

2/11/98 Hi folks, In the recent past I told you about a new metallurgical process that is being researched. The following work was done by Stan Wardle. The information is attractive and should be made available to general knowledge. Stan gave me permission to post it, I thank him for providing the information to me. Typically when leach processes are proposed, the amount of precious metals values that can be loaded into solution become important. For instance if an ore has .1 opt gold and the leachant is cyanide, the solution should be capable of retaining .1 opt gold as a minimum derived from the ore. If the ore needs repeated exposures of leach to achieve an optimum leach, the solution being contacted with the ore as multiple exposures will have to load to maybe .4 opt in the leachant if four exposures to ore are being made before the leachant is to be stripped of its values. The leachant can be increased in volume to lets say 2 times and then can load the .4 opt gold from 4 volumes of ore into solutions loaded to .2 opt gold. The new passive leach system being tested by Stan was loaded with maximum amounts of precious metals at ambient temperatures and atmospheric pressure. Since this is an early stage in the process development, the leachant is probably not an optimum, but the loading was so impressive that it certainly should be known to people investing in precious metals to be aware about new technology coming along on the tracks that may soon be available providing competition to other processes. Please understand that this has no bearing on the grade or values in any specific ore. It just is an indication of how much precious metals can be dissolved into the leachant at one loading. The results are reported in parts per million first and troy ounces per ton in the leachant second. Au - - 375.5 / 10+ Pd - - 523.6 / 15+ Pt - - 153.7 / 4.4 Rh - - 189.7 / 5.5 All of these metals were loaded into the same solution at the same time as well as additional major amounts of base metals as potential interferences. The chemical and energy required for the above tests was negligible. The metals were stripped from the solutions and tested as insurance that the AA results were accurate representations of the metals in solution. Additional advances: Time tests at my lab on ore tests have shown that the process is not subject to uncontrolled process reversals for at least 18 hours. The ores for those tests have been ground to minus 80 mesh Tyler. That is an important must if a process is to be effective. A series of tests will now test reliability or process stability for 72 hours. All work to date has been done with metals derived from DD ores from different deposits. However, we cannot predict results that will be obtained from deposits not yet tested or even different zones from within a deposit already tested. The work goes on. To the best of my knowledge no outside investor funds have been used for this work. Gradually, the risks in the process are being lessened. mike
