...from the Northern Miner:
Another company active in the Toodoggone region is Stealth Minerals (SML-V), which holds the 288-sq.-km Toodoggone project, just north of the Kemess North deposit.
Stealth stands to earn up to 100% of the property, subject to a 3% NSR, of which 1% can be purchased for $2 million. To earn a 60% interest, it must spend $5 million on exploration and pay $715,000 in cash to privately owned Electrum Resource by the end of November 2004. At the end of 2002, all payments had been made, and $2.3 million remained to be spent on exploration. Once vested, Stealth can issue 15% of its issued shares to Electrum to acquire the remaining 40% interest, or enter into a 60-40 joint venture with Electrum on a pro rata basis.
Under-explored
Stealth Minerals says the Toodoggone region, though rich in mineral showings, remains relatively under-explored. For example, the Toodoggone project hosts 30 separate mineralized prospects. Three deposit types are being targeted; skarn, epithermal and porphyry.
Subject to financing, Stealth hopes to spend a total of $3.2 million on the Toodoggone property in 2003.
The most advanced porphyry gold-copper deposit on the property is the Pine deposit. It is 25 km northeast of the Kemess South mine and has been subjected to 47 drill holes (7,889 metres). These holes were drilled between 1979 and 1999 by Rio Tinto (12 holes), Romulus Resources (13 holes), and Stealth (22 holes). The mineralized zone hosts about 160 million tonnes averaging 0.5 gram gold and 0.2% copper per tonne. In 2003, Stealth plans to drill six holes to test an induced-polarization (IP) anomaly east of the previous drilling.
In the previous season, Stealth explored four targets;
- Wrich Hill, a structurally controlled epithermal gold-silver prospect;
- Goat Mountain, which hosts several high-grade gold-silver polymetallic veins;
- the VIP copper-gold-silver skarn prospect; and
- the Mex gold-copper porphyry prospect.
The Wrich Hill prospect lies in the southern portion of the Toodoggone property, 14 km north of the Kemess South mine. Stealth geologists believe the Wrich Hill prospect is underlain by Toodoggone Formation crystal tuff just west of the regional Wrich fault. Kaolinite, pyrophyllite and iron-oxide surface alteration outline the prospect, which measures 200 by 850 metres.
Trenching
Trenching on a portion of the prospect revealed two steeply dipping sub-parallel mineralized zones close to the fault. Both zones remain open along strike to the northwest and southeast. The combined grade from four trenches in the West zone averages 1.36 grams gold and 9.87 grams silver per tonne over a true thickness of 28.5 metres. The combined grade from four trenches dug in the East zone, sub-parallel to the West zone, is 0.7 gram gold and 14.1 grams silver over an average true thickness of 18 metres. Both zones appear to be continuous in all of the trenches. Last year, a geophysical survey over the prospect defined a 200-metre-wide coincident chargeability and resistivity anomaly. Stealth plans to carry out a $900,000 exploration program, which would include drilling, prospecting and more geophysics.
The Goat Mountain prospect is 1 km west of Wrich Hill and hosts several outcropping sub-parallel epithermal-style quartz carbonate polymetallic veins and breccias. The southernmost vein, dubbed Black, has been traced on the surface for 300 metres and has produced the highest assays to date. A 40-cm chip sample returned 272.4 grams silver and 279.9 grams gold.
Stealth intends to spend $100,000 mapping and prospecting the prospect in the belief that the Goat vein mineralization and the Wrich Hill epithermal gold-silver prospects are spatially associated to a common, centrally situated mineralized porphyry that lies near the Takla sediment-Toodoggone volcanic contact and the Wrich fault.
The Wrich fault continues at least 7 km to the northwest, to the company's Electrum epithermal gold-silver prospect, where diamond drill results include 4.7 metres averaging 2.95 grams gold, 263.42 grams silver and 2.4 metres grading 4.9 grams gold and 459.62 grams silver per tonne. This fault zone is a prime target for epithermal gold-silver occurrences, as well as porphyry targets.
The VIP prospect is 10 km southwest of the Pine deposit and 20 km Northwest of the Kemess South mine. Mineralization occurs in skarns within marbles that were altered by the Blake Lake granodiorite intrusion.
A previous operator, in 1983, drilled seven holes. The best hole cut 3.43 grams gold, 5.77 grams silver and 1.36% copper over 3.05 metres.
Last year, Stealth performed IP and ground magnetic geophysical surveys, as well as geological mapping and prospecting over a 4.9-sq.-km grid. Data indicate that a continuous anomaly may exist between the East Skarn and the West skarn area, a distance of 1.9 km.
Mechanical trenching in the West Skarn area identified two zones of mineralization. The first assayed 0.1% copper, 2.6 grams silver and 0.83 gram gold over 6 metres, while the second returned 0.33% copper, 13.4 grams silver and 3.2 grams gold over 18 metres. Trenching in the East Skarn area of the prospect, 1.2 km east of the West Skarn trench, assayed 1.4% copper, 32.6 grams silver and 5.8 grams gold over 6 metres.
In addition, the company discovered a new prospect it has dubbed the North Skarn, 700 metres northwest of the East Skarn zone. A trench in this area assayed 1.16% copper, 52 grams silver and 3.6 grams gold over 6 metres.
Stealth reports that the North, West and East skarn zones exhibit favourable geology and that each represents drill targets. The company also believes that these zones may be part of a much larger, underlying intrusive system.
New showing
Prospecting 2.5 km west of the West Skarn, on open ground, identified a new showing where a grab sample returned 2.3% copper, 94.4 grams silver and 2.7 grams gold per tonne. As a result, crews staked a 10-km area around the showing. Alteration in this new area is described as more porphyritic. In addition the company's chargeability anomaly increases in the direction of this new discovery. Stealth intends to extend its grid to cover this new target in order to map and run geophysical surveys over the prospect.
The Mex gold-copper porphyry prospect is 22 km northeast of the Kemess South mine. Mineralization occurs near the contact between an intrusion and the Toodoggone volcanics and is characterized by a zone of intense hydrothermal alteration that measures 1 km wide and 300 metres down-slope. Cominco identified the prospect in the late 1980s with rock and soil samples that assayed up to 3.6 grams gold and 0.6% copper. The major did not follow up on the results. Last year, Stealth conducted geophysical surveys over the prospect, as well as mapping and sampling. Results warrant drilling, and the company plans to spend $400,000 on an 8-hole program. |
