The Hercules
The Hercules gold project has a history
dating back nearly 150 years, and has been estimated to have produced 5,000
ounces of gold and 20,000 ounces of silver from high-grade veins, historically
(source: Pioneer Mining Corp., 1992).
The
Hercules is located in southern Lyon County, approximately 40 km southwest of
Reno, and 11 km outside of Dayton. The Hercules is 16 km from the Comstock Lode
and 24 km from the Talapoosa Mine. The property consists of 40 mineral claims
covering approximately 800 acres of land. Regionally, the Hercules is located
within the Walker Lane, a structural belt extending more than 700 kilometers
through western Nevada and into California, which hosts several important gold
and precious metals deposits such as Comstock, Rawhide, Aurora, Paradise Peak,
Bullfrog, Goldfield, and Tonopah.
Exploration conducted by others to date, including Pioneer
Mining Corporation and Phelps Dodge Corporation, has led management of American
Goldfields to conclude that the Hercules contains significant concentrations of
gold. With more than $2 million USD in exploration expenditures and 197 drill
holes totaling more than 44,000 feet, the majority of the drilling to date has
been focused on shallow open-pit heap-leachable gold mineralization. Some of the recent drilling increased the known resource area, and defined new areas of gold and silver mineralization. The current drill program is offsetting gold mineralization within the new discoveries. Drilling is progressing with six holes completed.
According
to reserves studies done by Pioneer Mining Corporation and Horizon Gold, the
Hercules contains a resource of more than 217,000 ounces of gold and 1,571,000
ounces of silver. All of the resources remain open along strike and at depth. In
his annual compilation of major precious-metals deposits of Nevada, Tingley
(2000) quotes a resource for the Hercules of 259,329 ounces of gold and
1,956,511 ounces silver. The accuracy or validity of these estimates has not
been reviewed by American Goldfields.
Management considers the Hercules to be an
epithermal gold-silver mineralized system with direct analogies to the historic
Comstock Lode deposit. The historic Comstock Lode deposits of Virginia City
consist of a series of fault controlled vein systems which, between the 1860's
and 1880's, produced a significant quantity of rich gold-silver ore. Although
some mining occurred near-surface, the bulk of the gold and silver mined at
Comstock occurred below 1,200 feet. The Comstock bonanza-grade mineralization
averaged 2.0 ounces per ton gold and 50 ounces per ton silver.
With encouraging results on the previous two drilling programs, further testing of recently discovered, near surface gold mineralized zones throughout the property is being pursued. The current drilling is targeting previously untested, disseminated gold zones under reasonably shallow cover as well as testing nearby vein structures for high grade gold at depth.
Covering nearly 390 acres in the southern Lander County area of central
Nevada, the Gilman Gold Property is a structurally hosted gold mineralized
system consisting of 19 unpatented mineral claims.
Situated to the north of the Tonopah District, the Gilman Gold Property is 50
km north of the Round Mountain discovery, a deposit which has produced over 5
million ounces of gold and 3 million ounces of silver since it was first
discovered in 1901.
Located 60 km to the south is the Manhattan gold deposit. Manhattan currently
hosts proven and probable reserves of 1.7 million tons grading 0.13 opt
gold.
The Gilman Gold Property lies east of a major structure that separates the
Sierra Nevada batholith to the west from the Basin and Range province. The
prominent Walker Lane Belt, a zone of parallel and sub-parallel right lateral
strike slip faults, lies along this structural break. The primary focus of
exploration at the Gilman Gold Property is for structurally hosted high grade
gold mineralization. This style of mineralization is well documented in the
literature. The Santa Fe mine, located in Mineral County NV, hosts narrow zones
of steeply dipping gold and antimony-rich jasperoid occuring along fault
contacts. Reserves for the Santa Fe deposit are reported to be 6.8 million tons
grading 0.035 opt gold as of 1990.
Mineralization on the Gilman Gold Property is associated
with a steep, westerly dipping and northerly trending range front fault.
Sulphides identified include pyrite, arsenopyrite, galena and sphalerite. The
altered fault zone has a strike length of 9,000 feet. Previous exploration on
the property has been limited, and includes two small adits that exploited a
gossanous shear zone and vein structure. Numerous surface samples have returned
high grade gold (>1.4 opt).
The Gilman Project has received all permits and is ready to drill. Two to four holes are planned to test a high-grade gold bearing structures.
Crescent Fault
The Crescent Fault property ("Crescent Fault") is located in Eureka County,
three miles from the Mill Canyon deposit drilled by Newmont and five miles from
the Cortez mine. The property consists of 6 unpatented mining claims covering
approximately 120 acres.
The Crescent Fault has been explored by Homestake from 1983 to 1986, Noranda
from 1992 to 1994, and North Mining from 1995 to 1996, each of whom carried out
drilling. Sampling and mapping has also been carried out. A total of more than
10,000 feet have been drilled. Mineralization encountered in drilling includes
20 feet grading 0.11 opt Au, 25 feet grading 0.05 opt Au and 20 feet grading
0.035 opt Au. Management intends to drill between 6 and 10 holes next year that will offset known mineralization in historic holes and test new areas to the northeast of the present drilling.
The Bankop property
The Bankop property ("Bankop") is located in eastern Lander County, Nevada,
approximately 25 miles (40 km) southeast of Battle Mountain and four miles (6
km) northwest of the Pipeline Mine. The property consists of 24 unpatented
mining claims covering approximately 480 acres.
The property is within the Bullion
district, which includes the Tenabo and Mud Springs subdistricts to the north
and the Gold Acres subdistrict to the southeast. The Bullion district was first
prospected in the 1860's. Gold was discovered at Tenabo in 1905 and mined until
1912. Placer gold mining was conducted at Mud Springs and Mill Creek in the
early 1930's and the first gold was mined at Gold Acres in 1935.
Although there has been no production from the Bankop property to date,
recorded production for the district through 1977 is listed as 300,000 ounces
gold and 1 million ounces silver. The Bankop property has been explored since
1965. Exploration companies involved include US Mining and Exploration Company,
Phelps Dodge, Placer Amex, Cyprus Exploration Company, Homestake Mining Company,
US Borax, Placer Dome US, Noranda Exploration, (Hemlo Gold), Uranerz USA, and
Minorca Resources. The company believes this volume of geologic information is a
valuable tool for further study of the property.
Regionally, the area is situated within the
Battle Mountain-Eureka Trend, a northwest striking 30 to 40 mile wide (45 to 60
km) belt. This trend defines the second most productive gold province in the
United States. Gold Acres, located three miles (4.5 km) to the southeast of the
Bankop property, is the closest Carlin type mine. Significant gold intercepts of
Carlin style mineralization occur on the Bankop property around a trench where
sampling detected up to 1.4 g/t gold. Several holes drilled in this area had a
high of 0.7 g/t over 5 feet (1.5 m).
The company has completed seven drill holes and is very encouraged with preliminary findings. Result will be available upon completion of laboratory testing.
Bullion Mountain
The Bullion Mountain property ("Bullion Mountain") is located in Lander
County, along the Pipeline trend, approximately 6 miles northwest of the
Pipeline deposit and 12 miles southeast of Battle Mountain. The property
consists of 20 unpatented mining claims covering approximately 400 acres, which
include a group of claims known as the Bully claims and the Chief claims.
The property may have been prospected as early as the 1870's during the Utah
Camp and Cortez boom, and it contains numerous prospect pits and shallow adits.
It lies along the Pipeline fault zone, and has been previously explored by
Placer Dome, Asarco, Hemlo, Lac, Barrick and Pallum. Drilling has been carried
out on the claims by Asarco and also Placer Dome and Pallum. Surface samples
have identified high grade gold (>0.5 opt) in fault zones in upper plate
rocks. Drilling has encountered 3 meters of 0.204 opt Au on the Bully claims and
1.5 meters of 0.08 opt Au of 15 meters of 0.02 opt Au on the Chief claims. The
nearby gold deposits of Hilltop and Dean occur within the same upper plate
rocks, and both deposits contain significant high grade gold in veins with lower
grade gold values hosted by breccia zones.
Regional Overview
Regionally, the Crescent Fault, Bankop, and Bullion Mountain properties are
located within an area which includes the prolific gold-producing Pipeline /
South Pipeline / Cortez Hills / Pediment deposits whose gold production is
estimated at 15.7 million ounces over a projected 17-year mine life with 88%
recovery [source:mining-technology.com re Cortez Gold Mine]). The Hercules and Gilman properties are located within the Walker Lane, a structural
belt extending more than 700 kilometers through western Nevada and into
California, which hosts several important gold and precious metals deposits such
as Comstock, Rawhide, Aurora, Paradise Peak, Bullfrog, Goldfield, and
Tonopah.
Management is very excited about its initial review of the property's
geological data.
