Excellent Met-Test Results for Fischer-Watt's La Balsa Project.Business Editors Fischer-Watt Gold Company, Inc. (OTCBB OTCBB See OTC Bulletin Board (OTCBB). :FWGO) has received the results of a metallurgical column-testing program carried out on its La Balsa La Balsa was the name of a 1970 expedition led by Spaniard Vital Alsar to sail a Balsa raft from South America to Australia across the Pacific Ocean. The 8,600 mile voyage was, at the time, the longest in known history, only eclipsed by the 1973 Las Balsas expedition, again led by copper ore by Mountain States The Mountain States (also known as the Mountain West) form one of the nine geographic divisions of the United States that are officially recognized by the United States Census Bureau.

Results of the study determine whether the solution should be implemented. . As previously reported, Fischer-Watt conducted a diamond drilling program, in the latter part of 2001, in order to recover core samples of the copper ores for metallurgical testing, certification of reserves, and to provide environmental and geotechnical information. The core from the various mineralized min·er·al·ize v. min·er·al·ized, min·er·al·iz·ing, min·er·al·iz·es v.tr. 1. To convert to a mineral substance; petrify. 2.

The head grades of the samples were representative of each of the ore types, namely, oxide ore at 2.75% copper, transitional sulfide ore at 1.78% copper and primary sulfide ore at 1.09% copper, two sets of samples were prepared one at a crush size of (-) 1 inch and the other at (-) 1/2 inch. These two sets of samples were column leached for 100 days. The (-) 1/2 inch samples returned the best results. The copper recovery in both the oxide and transitional sulfide ores was excellent and acid consumption was low in both cases. The recovery curves for the (-) 1/2 inch samples show good leaching characteristics with a total recovery of 93.9% of the copper in the oxide ore and 92.4% of the copper in the transitional sulfide ore. The date from the column leach test were evaluated by Leach, Inc. for the purposed of projecting copper recovery under various commercial operating scenarios. The column data indicated that copper recovery is controlled by the availability of the leaching reagents and it was calculated that 90 to 92 percent of the copper could be solubilized in 123 days of leaching using typical heap leach operating parameters. Copper recoveries would be somewhat lower than this due to normal inventory build up in the leach heaps and operating inefficiencies. Comparable recoveries can be attained in between 76 and 245 days of leaching by varying the operating parameters. The precise operating parameters have not yet been established and will be the subject of the engineering design program currently been negotiated. The third ore group, the primary sulfide ore, is derived from the deeper La Balsa porphyry Porphyry, Greek scholar Porphyry (pôr`fĭrē), c.232–c.304, Greek scholar and Neoplatonic philosopher.

At the present time this primary sulfide resource represents the second phase of mining that will take place at the property after the oxide and transitional sulfide ores have been mined. Copper recovery of 41.7% was much lower in this ore, as expected, and acid consumption was high. However, some interesting metallurgical opportunities were brought to light during the testing. For example, preliminary testwork has indicated that Heavy Media Separation can significantly upgrade this primary sulfide ore, which responds very well to standard flotation concentration, prior to flotation.

This reduction would likely appreciably lower the capital cost of the processing plant. There are other options available also for treating the primary sulfide ore and they will be examined as the development of the oxide and transitional sulfide ore moves forward.

The very high copper recoveries that we have received from the ores in the oxide and transitional sulfide zones certainly strengthens our Company's resolve to move forward with this plan".
