SINCHAO PROJECT ASSAY VARIATIONS
The initial results of the comparison between the "Air Classification Coarse Gold Fire Assay Method" (CGA (Color/Graphics Adapter) The first video display standard for the IBM PC. This low-resolution system was superseded by EGA and then VGA. CGA required a digital RGB Color Display monitor. See PC display modes.

2. To represent in words; describe. See Synonyms at represent. below(a) in graphical form for 44 samples of gold. Similar results were obtained for copper and silver values.
This significant variation has caused a decision to apply the "Air Classification Coarse Gold Assay Method" over all 1998 diamond drill results which have been determined to be "Representative Samples".
Representative samples are defined as those samples that have a recovery of 80% or higher as verified through our Quality Assurance Program.

SINCHAO DRILLING - UPDATE
Listed below is the status of physical progress for diamond drilling Diamond Drilling is a highly specialized industry used for mineral exploration around the world. Most commonly using wireline and core bits with diamond encrusted matrix. To drill holes to max depths of twelve thousand feet, for the recovery of core used in verifying mineral to July 15, 1998:
HOLE SDH-02: Was completed at 629.7 meters (true depth of 545.3
meters) as previously reported. Assays have been received for the entire hole. CGA (Coarse Gold Assay) awaited.
HOLE SDH-03: Was completed at 492 meters (true depth of 475.2
meters). Assays have been received for the entire hole. CGA awaited.
HOLE SDH-05: Hole was completed at 498.7 meters (true depth of
434.5 meters). Assays have been received to 472 meters. CGA awaited.
HOLE SDH-06: Hole was completed at 816.5 meters (true depth of
740.0 meters). Assays have been received to 690 meters. CGA awaited.
HOLE SDH-07: Current depth 789 meters (true depth of 683.3
meters). Awaiting all assays.
HOLE SDH-08: Current depth 447 meters (true depth of 387.1
meters). Awaiting all assays.
HOLE SDH-09: Hole abandoned at 158.1 meters (true depth of
136.9 meters). Awaiting all assays.
HOLE SDH-10: Current depth 84 meters (true depth of 136.9
meters). Awaiting all assays.

DEVELOPMENT CONCEPT - SINCHAO
The Company's development concept at Sinchao embraces open pit mining using electric power, single stage crushing, as well as two stage grinding and flotation flotation

2. In the acts of Congress, the term is also applied to copper properly manufactured for the purpose of being coined into money. .
The Company's preliminary economic evaluation indicates the importance of a low cost energy source for the project, both in terms of operating and capital cost. The Company has identified such a source and steps are being taken to secure this supply.
The results of these discussions will be released in later news releases. Additionally, a high-grade starter feed resource needs to be established in order to accelerate the repayment of the capital cost. Preliminary indications suggest target recoveries of 80% for Copper, 50-70% for Zinc, Silver and Gold.
These results are based upon flotation testwork that the Company completed where 90% of the Copper, Zinc, Silver and Gold contents of the feed samples reported to the bulk concentrates.
The conceptual economic model will be further defined as metallurgical met·al·lur·gy

Initially, bench scale tests will be conducted.
SANTA ROSA Santa Rosa, city, Argentina
Santa Rosa, city (1991 pop. 80,629), capital of La Pampa prov., central Argentina. It is a modern city and road junction surrounded by a rich agricultural and cattle-raising area. PRE-FEASIBILITY
The Company has retained Roscoe Postle Associates to complete a pre-feasibility study for the Santa Rosa project using the conventional carbon in pulp treatment.
Estimated completion time is October 31, 1998. Metallurgical results have indicated that the most viable option is to use the Dodd/Sceresini Transportable Treatment Plant with evaluation of the 2000 - 3000 TPD TPD Tons Per Day

Metallurgical test work using Atomaer Reactor technology has been received from K.D Engineering out of Tucson Arizona. This testwork has indicated acceptable recoveries of gold and silver from oxide and sulphide sulphide: see sulfide. samples.
SAN NICOLAS San Nicolas or San Nicolás ("Saint Nicholas") may refer to:
The Company has retained Roscoe Postle Associates to complete a pre-feasibility study on the San Nicolas Mine and Heap Leach Operations. The San Nicolas Plant and Heap Leach Operations are conveniently located 3 km from the Sinchao Property and the San Nicolas Mine.
Pre-Feasibility studies will include the evaluation of the Consulado Project and the Sinchao high grade mantos mineralization. The pre-feasibility will encompass resource estimates. Open pit mine design and metallurgical evaluation will be done using alternative hydrometallurgical technology and environmental assessment.
Based on recommendations from Independent Consultants, the Company is planning to drill 2010 meters at Consulado in 21 holes as well as 3,000 meters of reverse circulation drilling on the Sinchao mantos in 15 holes in order to establish resource estimates.
The estimated completion date for the pre-feasibility study is December 31, 1998.
