Exploration
El Compa
Location and Access
The El Compa consists of exploration concessions totaling 5,558 hectares, located just to the north of the village of Sahuaripa in eastern Sonora state, some 297 km by paved highway east of Hermosillo, the state capital. A gravel airstrip suitable for light aircraft is present at Sahuaripa. Access to the property is by a network of gravel ranch roads from Sahuaripa and then by roads constructed by the Company.
Regional Geology
The area is an extensive zone of exposed tertiary volcanics, mainly pyroclastics, tuffs,
breccias, ignimbrites and some lavas of andesitic, rhyolitic, composition intrusives. All
the former are deposited on Cretaceous volcanics and sediments and Paleozoic sediments.

The dominant structural features are northerly and northwesterly trending faults. Some of
the northwest trending faults have caused basement overthrust toward the east. Several
centres of hydrothermal activity are believed to be present in the area.
History
Small-scale gold and silver mining in the area around the El Compa Project is believed to
pre-date the Spanish Conquistador era. From Spanish times to the early 1900's gold and
silver mining continued on a somewhat larger scale and in the late 1800's to the early
1900's mining of copper , zinc, lead, silver and gold veins took place. Some of these
small mines were sufficiently high-grade that concentrates were shipped via mule, barge
and then rail to El Paso for refining.
Placer mining took place on the Yaqui river, down slope from the Argentina-Santa Fe
claims and local prospectors still work the regions weathered vein systems with hand
tools.
The company's holdings in the Sahuaripa area in the State of Sonora, Mexico constitute
an inventory of gold-bearing gossans that appear to represent the potential for the
existence of large low-grade heap-leach gold deposits amenable to open-pit mining as
well as low volume, steeply dipping high-grade gold deposits amenable to low cost
underground mining utilizing adits and ramps.
In the past three years the Company expended US$147,152 on the property for geological
mapping, airborne geophysical surveys, reconaissance and detailed geochemical survey,
ground I.P. survey, surface taxes and 29 short reverse circulation drill holes. No funds
were expended in the years 2000 and 2001 to date.
Drilling Program
This project covers old workings of a gossanous intrusive area 1000 m by 1000 m, and
consists of steeply dipping gold-bearing veins and veinlets. Two of induced polarization
(I.P.) resistivity surveys carried out by Zonge Engineering of Tucson, Arizona and Bar
Geophysics of Durango, Colorado, USA covering an area 890 metres by 1840 metres
with line spacing between 160 and 200 metres and totaling 14.5 line kilometers as well as
a geochemical survey utilizing the Mobile Metal Ion Geochemical process (MMI) were
completed over the property. Four north trending parallel, I.P. Resistivity Anomalies, all
of which are either open to the north, south or both, have been defined by the I.P. survey.
Three of these I.P. anomalies have strong coincidental geochemical MMI gold anomalies.
A total of 29 short reverse circulation drill holes including the original 11 scout drill
holes tested a number of exposed gold-bearing areas as well as geochemical and
geophysical anomalies on the property. It is believed that about 20% of the favorable
horizons as defined by I.P. and geochemical surveys have been tested by drilling to date.
Of the area tested to date four north-trending, gold-bearing zones were delineated by
drilling down to a vertical depth of about 75 metres (245ft) as tabulated below:
