Main SUN Deposit
The Company’s 100% owned silver-copper-lead-zinc-gold VMS (volcanogenic massive sulfide) mineralization on the Main Sun Deposit has been drilled along approximately three kilometers of strike but the highly prospective meta-volcanic Ambler Schist Belt has been traced approximately another 16 kilometers on the Andover claim block.
A Historical Four Volume Pre-feasibility Study on the Sun Deposit (Pre National Instrument 43-101) conducted for Anaconda Copper Mining Company in 1977 by Canadian Mine Services Ltd., Kilborn Engineering (B.C.) Ltd., and Swan Wooster Engineering Co. Ltd, and projected the following resources. These historic resource calculations were done prior to the implementation of National Instrument 43-101 and are not compliant with National Instrument 43-101 and therefore should not be relied upon.
| Tons | Silver | Copper | Lead | Zinc | |
| Open pit | 2,399,000 | 2.39 opt | 1.93% | 1.20% | 4.51% |
| Underground | 17,891,000 | 2.37 opt | 1.91% | 1.18% | 4.46% |
Drill Program
With the completion of the 2011 drill program, the project has 76 drill holes completed at the SUN. Andover completed 27 of these drill holes along with a further 49 drill holes completed by previous operators. Approximately 49,000 feet of drilling has now been completed by various mining companies on Andover’s SUN property including: Andover, Anaconda, Norandra, Cominco and Bear Creek.
A selection of assay results from the 2011 drill program for the Main SUN Deposit are outlined below.
Main SUN Deposit, selected intercepts:
| Drill Hole No. | From (m) | To (m) | Interval (m) | True | Thickness (m) | Cu (%) | Pb (%) | Zn (%) | Ag (g/T) |
|---|---|---|---|---|---|---|---|---|---|
| Sun11-24 | 67.5 | 84 | 16.5 | 15.0 | 1.60 | 3.49 | 10.25 | 80.64 | 0.32 |
| Sun11-28 | 57.45 | 68.00 | 10.65 | 10.01 | 2.56 | 0.81 | 4.47 | 63.8 | 0.216 |
| Sun11-28 | 124.75 | 125.00 | 0.25 | 0.23 | 11.40 | 0.29 | 2.50 | 244.0 | 1.540 |
Sun11-28 was successful in proving continuity of thickness and grade through this important portion of the Sun Deposit. Significantly, the zone in Sun11-28 below the massive sulfide horizon contained abundant stringer chalcopyrite and saphalerite. The stringer zone, logged at depths of 65.55 – 72 meters (6.45 m), containing an average grade of 1.19 % Cu, 0.20 % Pb, 1.05% Zn, 22.0 g/T Ag and 0.003 g/T Au, is believed by the onsite geologists to indicate that the feeder zone for the Sun Deposit has been intersected.
Highlights of the 2007 Exploration Program – Sun Deposit
- 1,500 foot permanent airstrip.
- Geochemical sampling along the strike.
- Two Boart-Longyear LF 70s drilled 4,496 meters (14,750 feet) of NQ2 core in 20 holes in 2007
- Nineteen of the twenty holes encountered mineralized zones ranging from an estimated 1.20 to 37.01 meters (3.9 to 121.42 feet) thick.
The 2007 drill program tested along 1.4 kilometer strike. - Seven of the holes encountered two mineralized horizons.
- Two drill holes encountered three mineralized zones.
- Thirty total intersections were encountered and average over 6 meters
(20 feet) thick of massive and semi-massive mineralization. - Discovered/identified a new thickened zone.
- Extended the strike length by 300 meters north.
- Discovered lower “Hot” zone, up to 30.0 meters thick, open in both directions.
Andovers 2007 drill program intercepted six (6) fold thickened intercepts over the 500 meters, which average 35.5 meters thick hosting an average grade of 1.05% Cu, 0.81% Pb, 3.26% Zn, 42.9gm/t Ag and .176gm/t Au.
