The Company is in the process of establishing the most economical and financially feasible methods to extract and mine their gold and silver deposits, and which of the existing equipment will be most effective in conjunction with the new equipment, for the extraction of first grade pure manganese manganese (măng`gənēs, măn`–) [Lat.,=magnet], metallic chemical element; symbol Mn; at. no. 25; at. wt. 54.938; m.p. about 1,244°C;; b.p. about 1,962°C;; sp. gr. 7.2 to 7. , as well as gold and silver. Rock and Tailings Tailings (also known as tailings pile, tails, leach residue, or slickens[1]) are the materials left over[2] after the process of separating the valuable fraction from the worthless fraction of an ore. Sampling Two hundred and ten rock chip, channel and tailings samples were acquired and assayed for gold, silver and other elements from July to December 1999. Metallurgical met·al·lur·gy n. 1.

However, manganese appears to be present in all mineralized quartz veins on the property, including the veins of the existing underground mine. This has also been confirmed from tailings, which are derived largely from ore from the mine. Assays of surface samples reveals near-surface concentrations averaging about 1% to 1.5% manganese. Several samples of vein material from stored diamond drill core was also assayed and averaged about 0.5% manganese. All samples were assayed by Intertek Testing Services (Bondar Clegg) in Jakarta, Indonesia. Five closely-spaced and en-echelon east-west trending trenches were excavated to locate and channel samples across the 2 to 5 meter wide mineralized quartz vein structure which is the principle producer to date on the property. The samples were taken from the surface of the deep crown pillar over the mine from which about 40,000 tonnes of ore was mined from 1988 to 1992. Only one trench sample, TR25E99019, returned a significant assay of value (Table No. 6). A 15-meter diameter circular pit a few meters north of the mill was sampled. The pit, excavated in 1998, surrounds the now-nonexistent trench TR-96-No. 2 which had 2.68 g/T Au and 88.3 g/T Ag over 22 meters. Fifteen face bulk samples were taken, each from a face 2 meters wide and 2 to 3.5 meters high. Significant values are shown in Table No. 6. Tailings Sampling Specific Four random samples of tailings were taken from depths of up to 1 meter from the series of tailings ponds immediately below the mill. The assay results combined with the fact that the tailings ponds hold most of the approximately 40,000 tonnes of material mined to date indicate that there is a considerable gold, silver and manganese resource in the tailings. It is known that gold and silver recoveries have historically been very poor. It is believed that more than three quarters of the precious metals Precious Metals Valuable metals such as gold, iridium, palladium, platinum, and silver. Notes: Investing in precious metals can be done either by purchasing the physical asset, or by purchasing futures contracts for the particular metal. content of the original ore remains within the tailings. The assays of three tailings samples, TAG-1 to TAG-3, are presented in Table No. 6.

Geological Mapping Geological mapping of the property in 1999, supported by petrographic pe·trog·ra·phy n. The description and classification of rocks. pe·trog ra·pher n. thin section studies, has established that three separate
areas of the property previously believed to be granites are in fact
highly altered andesites. Four rock specimens from outcrops previously
mapped by Robertson Research International in Jakarta and Great Britain Great Britain, officially United Kingdom of Great Britain and Northern Ireland, constitutional monarchy (2005 est. pop. 60,441,000), 94,226 sq mi (244,044 sq km), on the British Isles, off W Europe. The country is often referred to simply as Britain. examined granites and have all been classified as andesites. This has
positive implications for the exploration potential of the area
immediately south of the base camp, an area that has not been properly
explored due to the earlier belief that it is granite and therefore
would not host economic mineralisation.One previously reported granite intrusion is situated within an ovoid o·void or o·voi·dal n. Something that is shaped like an egg. adj.

Line 9800 N of the IP survey was conducted across the center of the area and the IP profile provides no indication of an intrusive body in this location. Rather, the line 9800N profiles are similar to the profiles of the other survey lines conducted across mapped andesitic volcanic rocks rocks which have been produced from the discharges of volcanic matter, as the various kinds of basalt, trachyte, scoria, obsidian, etc., whether compact, scoriaceous, or vitreous. See also: Volcanic to the north and south. The IP similarities from grid line to line include a similar range of numerical values (resistivity resistivity Electrical resistance of a conductor of unit cross-sectional area and unit length. The resistivity of a conductor depends on its composition and its temperature. , chargeability, and metal factor) and a similar variety of apparent geological structures. This area previously mapped as a granite intrusion (Gewargis "Granite Unit No. 1") was then further investigated and two new gold-silver mineralized veins were discovered; one in a dry creek Dry Creek may refer to:
Conclusion It appears that CKS is in a unique position, whereby the manganese problems in the recovery process of the past, can actually be resolved through a new method of recovery. Process Research Analytics in Vancouver are currently in the process of completing the final phase of test work, to determine the most effective recovery methods, on the KBU site. Although no conclusive results are available at this time, strong indications exist that adequate recoveries of gold, silver and manganese can possibly be achieved. The company hopes to make preliminary results available shortly. On behalf of the Board of Directors, CONSOLIDATED SILVER TUSK MINES LTD. William J.
