TOODOGGONE PROJECT - THE LOUIS CLAIMS
Available for Option
Introduction
The Louis Property represents a quality exploration opportunity in British Columbia's prolific Toodoggone Camp. The property has seen $1million in previous expenditures directed primarily towards shallow, low-sulphidation gold-silver vein-type mineralization. Considerable exploration potential exists for deeper epithermal and porphyry, Kemess-type copper-gold mineralization in the claims area.
BCGold holds an option to earn 75% interest in the Louis Property from Stealth Minerals Ltd. A NI43-101 technical report has been prepared for the property which would allow the Louis Claims to could serve as a listing property. BCGold is seeking a qualified joint-venture partner to advance this exploration opportunity.
It is estimated that more than $10 million will be spent on exploration in the Toodoggone Camp in 2007. This includes a $1.5 million exploration program by BCGold Corp. on the nearby Sickle-Sofia Property.
Property Location
The Louis Claims are located in the Toodoggone District of north central British Columbia, approximately 430 kilometres northwest of Prince George, 50km north of the Kemess South Mine.
The property comprises 9 adjoining mineral claims containing 3,157 hectares. The Louis Claims are accessed via the partially deactivated road north of the Sturdee Air Strip. An airstrip is also in place at the Kemess South Mine. The Louis prospect is located to the northwest of the Lawyers (Bishop Gold), Baker and Shasta (Sable Resources) gold-silver deposits and to the southeast of the Al (Christopher James Gold) gold-silver deposit. The geologic setting, alteration and structural controls are similar to these deposits.
History
A total of $1,000,491 in exploration expenditures have been filed for work on the Louis Claims. Recorded exploration of the property dates back to 1971, when Kenco Exploration undertook geochemical and geophysical surveys of the area. Through the 1980s, exploration of the Louis claims was undertaken by several operators, most notably Cyprus Metals, who conducted geological, geochemical and geophysical surveys, trenching and diamond drilling totalling 13,708m. Three epithermal Au-Ag vein showings are recorded in MINFILE for the Louis Claims. Most recently, Stealth Minerals has undertaken mapping of lithology and alteration in outcrop and historic diamond drill core. The existing geological, geochemical and geophysical data have been compiled into a comprehensive GIS database. In 2006 a MMI soil geochemical survey was successful in identifying areas that correlate directly to mineralization intersected in historical drill holes. The MMI data also outlined new areas with potential for epithermal gold-silver mineralization. Based on airborne geophysics and other data, the property is also prospective for bulk tonnage porphyry style copper-gold mineralization.
BCGold commissioned Dr. Ken Dawson, PhD, P.Geo. to complete a 43-101 technical report for the property.
Geology and Mineralization
The Louis Claims are situated in the Toodoggone Region of north central British Columbia. The Toodoggone lies within the Stikine Terrane at the eastern margin of the Intermontane Tectonic Belt. Numerous mineral deposits occur within the Toodoggone and are associated with the early Jurassic Black Lake Intrusive Suite, or the co-genetic volcanic rocks of the Toodoggone Formation (Hazelton Group). Deposits in this region include past (Baker, Cheney) and present (Kemess South) producers.
Two major structures are recognized on the Louis Claims, the Attorney Fault and the Cliff Creek Fault. The structures are believed to be continuous along strike to the southeast, where they are observed at the Lawyers deposit. The attitude of the Attorney Fault, is well documented due to its association with the past-producing Cheney mine. This structure extends over approximately 40km from Baker Mine in the South to Adoogacho Creek on the north. Strike along its length is essentially constant at 330º and dip is vertical. The Cliff Creek fault, which is locally mineralized with quartz, gold, silver and minor pyrite, is 2200m west of and sub-parallel to the Attorney Fault. These structures may be temporally-linked to hydrothermal Au and Ag mineralization in the Toodoggone Formation volcanic rocks.
Historic work on the property work occurred between 1971 and 1989 and identified three parallel, structurally controlled northwest trending corridors of potassically altered Jurassic volcanics that host low-sulphidation epithermal precious metal vein systems within wider zones of silicification and alteration.
Between 1986 and 1989, 43 shallow diamond drill holes totaling 4,107 metres tested the Moosehorn veins on the north side of the Toodoggone River.

The known mineralization is partially controlled by two regional northwest trending fault systems- the Cliff Creek and Attorney faults - and the local Moosehorn fault, which lies between the regional faults.
The property is host to four Minfile showings:
- 94E 158 -- Round Mountain East: a large-scale argillic altered zone
- 94E 159 -- Round Mountain West: a gold-silver quartz vein
- 94E 068 -- Kodah: a pyritic quartz vein with gold and silver values
- 94E 086 -- Moosehorn: a series of gold and silver veins
A 2003 multi-parameter, helicopter-borne geophysical survey identified a large magnetic anomaly in the northeast corner of the Louis Claims with a greater than 6km2 halo of anomalously low eTh/K values. This geophysical pattern may be indication of a strongly potassic altered halo to a moderately magnetic intrusive body, emplaced below the volcanic cover. Elsewhere on the property, historic geochemical surveys have outlined coincident Cu and Au soil anomalies. A single line of MMI soil geochemistry has identified anomalous Cu greater than 440 ppm. Historic drillholes in the area of the eTh/K anomaly were generally less than 150m deep, which suggests that the Louis Claims have considerable untested potential for deeper epithermal vein and Cu-Au porphyry mineralization.
Discussion
Historical drilling on the property was shallow in nature and did not penetrate further than 90 metres below the surface. Precious metal values were low, returning 2-5 ppm gold and up to 60 ppm silver. It is suggested that mineralization drilled tested to date is high-level in the epithermal system, and that deeper drilling is required to more adequately assess the precious metal core of the mineralizing system. The strong magnetic high and annular RTK low in the northeast corner of the property suggests hydrothermal alteration associated with a central unroofed porphyry intrusive. A program of IP and deeper drilling is warranted to adequately test the true potential of the Louis porphyry concept.
Exploration on four primary targets on the Louis prospect have been recommended in the Technical Report:
- Exploration work to date suggests that a higher grade epithermal system may be located deeper than has previously been drilled on the Moosehorn vein target. Induced polarization surveys done in 1987 penetrated only to depths of about 50 m. A deeper I.P. survey that penetrates to depths of 200 m to 300 m should be run across the Moosehorn Zone and the combined magnetic and potassium anomalies to the northeast to identify a porphyry pluton at depth.
- The mineralizing Cliff Creek Fault and Attorney Fault cut the Round Mountain area and are excellent mineral target. Further detailed prospecting and trenching should be completed on the north western and north eastern portion of Round Mountain in the vicinity of the 2006 MMI anomalies.
- In order to examine the potential of a larger vein system at depth and to determine the source of these veins, deeper drill holes are recommended. A drilling program consisting of a line of roughly 4 x 250m diamond drill holes in the region of the Moosehorn Veins is recommended.
- Drilling at least three, 300m holes under the new geochemical anomaly at and east of the Attorney fault should be completed to test for further epithermal vein zones. At least one, possibly 400m drill hole would test if there may be a mineralized causative porphyry deposit located beneath this strong potassically altered epithermal mineralized zone. These proposed drill holes will be located on the basis of geophysical anomalies generated in the 2007 survey. Minor road upgrades would also be necessary on the existing road and would allow easy and less expensive access to the Louis property.
