ECHO BAY IOCG & URANIUM PROJECT 2007




Echo Bay Gossan-IOCG Target
The Echo Bay IOCG & uranium target drill program was designed to re-evaluate the economic potential of the former Eldorado-Echo Bay silver and uranium mines and its untested surrounding area. The Echo Bay silver-uranium target area is located on the Company's property, on the north side of Echo Bay. Many drill holes reporting, intersected multiple zones of altered and mineralized poly-metallic zones with disseminated and vein hosted high grade copper, silver, lead and zinc.

  • EBM-07-06 intersected 7.50 meters of 0.18% copper and 0.12% zinc within that 1.50 meter 0.42% copper. Another zone of 0.58 meter of 0.43% lead was also intersected in this drill hole.
  • EBM-07-08 intersected 24.75 meters of 2.50% lead, 0.49% copper, 0.31% zinc and 26.50 g/ton silver, within that 4.50 meters of 8.38% lead, 0.50% copper, 0.68% zinc and 34.4 g/ton silver. Also several mineralized zones enriched in copper, lead or zinc were intersected in this drill hole.
  • EBM-07-09 intersected several zinc-bearing zones including 3.0 meters of 0.27% zinc, 2.9 meters of 0.38% zinc, 1.5 meters of 0.20% zinc and 6 meters of 0.22% zinc. Also 1.5 meters of 0.27% copper was intersected.
  • EBM-07-11 intersected several mineralized zones including 58.25 meters of 0.61% zinc, 0.20% lead, and 2.44 g/ton silver and within that 1.50 meters of 2.56% zinc, 0.43% lead and 6.63 g/ton silver and also 1.50 meters of 2.35% zinc, 0.79% lead and 3.90 g/ton silver was intersected in this drill hole.
  • EBM-07-12 intersected 15.50 meters of 0.54% zinc and 0.20% copper and 3.29 g/ton silver including 2 meters of 0.16% copper, 0.30% lead, 1.27% zinc and 3.33 g/ton silver. Other mineralized zones include 3 meters of 0.43% lead and 0.14% zinc and 4.0 meters of 0.1% copper, 0.56% lead, 0.19% zinc; 3 meters 0.16% lead and 0.39% zinc.
  • EBM-07-13 intersected 30.10 meters of 0.75% zinc, 0.28% lead. Another zone of 0.25 meter of 16.47% zinc, 0.64% copper, 0.46% lead and 403.0 g/ton silver. Also several mineralized zones enriched in copper, lead or zinc were intersected in this drill hole.
The accompanying table gives a summary of drilling highlights and assay results from the first four holes at Echo Bay IOCG and uranium target.

Drilling Map 2006
The initial drill results discovered a new zone of hydrothermal and structurally controlled poly-metallic vein breccias that are enriched in silver, copper, nickel, cobalt, lead and zinc. The Echo Bay silver-uranium target is located on the Company's property, on the north side of Echo Bay. The Company has intersected 10.5 meters (34.7 feet) of 117.1 g/ton silver (3.77 ounces per ton), 0.14% copper, 0.46% lead, 0.21% zinc and 0.18% nickel at Echo Bay in Canada's Northwest Territories. This interval also included 5.0 meters (16.5 feet) of 237.9 g/ton silver (7.65 ounces per ton), 0.24% copper, 0.45% lead, 0.20% zinc, 0.37% nickel and 0.09% cobalt which includes 1.50 meters (4.95 feet) of 739.5 g/ton silver (23.79 ounce/ton), 0.19% copper, 0.56% lead, 0.45% zinc, 1.20% nickel, 0.22% cobalt. A half meter zone of high grade 2,186.0 g/ton silver (70.33 ounce per/ton), 0.78% zinc, 3.57% nickel, 0.31% copper and 0.65% cobalt was also intersected in this interval.

Completion of the five drill holes confirms additional poly-metallic mineralization at Echo Bay. Three of five drill holes intersected multiple zones of altered and highly mineralized poly-metallic breccias with disseminated and vein hosted copper, silver, cobalt, nickel, lead and zinc mineralization. One hole was abandoned and one did not return significant results.

Highlights from significant mineralized down-hole intervals from the three new holes reporting significant values, include hole number:

  • EBM-06-02 intersected 10.5 meters (34.7 Feet) of 117.1 g/ton silver (3.77 ounces per ton), 0.14 copper, 0.46% lead, 0.21% zinc and 0.18% nickel.

  • including 5.0 meters (16.5 feet) of 237.9 g/ton silver (7.65 ounces per ton), 0.24% copper, 0.45% lead, 0.20% zinc, 0.37% nickel and 0.09% cobalt.

  • including 1.50 meters (4.95 feet) of 739.5 g/ton silver (23.79 ounces per ton), 0.30% copper, 0.47% lead, 0.45% zinc, 1.20% nickel and 0.22% cobalt.

  • including 0.50 meters (1.65 feet) of 2186.0 g/ton silver (70.33 ounces per ton), 0.78% zinc, 3.57% nickel, 0.31% copper and 0.65% cobalt.

  • EBM-06-03 intersected 22.50 meters (73.8 feet) of 2.7 g/ton silver, 0.21% lead and 0.72% zinc.
Other significant poly-metallic IOCG style mineralized down-hole intervals at: EBM-06-02 included 3.0 meters (9.9 feet) of 1.26% lead, 2.75% zinc and 8.2 g/ton silver.

The Echo Bay Mine district is being targeted for silver and uranium exploration. The mineralization occurs within the same suite of volcano-plutonic rocks that host other poly-metallic zones in the Eldorado & Contact Lake Mineral Belt, including the former El Bonanza Silver (Ag) and the Eldorado Uranium (U-Ag- Cu- Co- Ni- Bi) mines. Veins of the former Eldorado and Echo Bay mines are situated in metasedimentary rocks, near the margins and apices of porphyry stocks, between underlying batholiths and overlying volcanic rocks. The cores and intermediate zones of the hydrothermal systems that are responsible for these veins are possible loci for larger, more typical, bulk-mineable IOCG-type deposits. Additional drill results are pending and will be released when they are received by the Company.

The accompanying table gives a summary of drilling highlights and assay results returned from three out of five holes reporting from Echo Bay at Eldorado, NT.
