Further drilling is required to establish true widths of the above intercepts for holes AT-11-01 and AT-11-02. Final assaying for all of the above first three holes, as well as final QA/QC is pending and ongoing.
The first hole of the program (AT-11-01) was originally interpreted to be drilled obliquely down dip into the Footwall andesites to test for geology and mineralization at depth. The hole intersected 657m of the altered Footwall andesites with some sections containing significant gold and copper mineralization as outlined in the above table. From past and current drilling, the width of the Footwall Zone is estimated to be at least 150m wide and at least 500m long and represents a significant new discovery on the Atikwa Lake property. The above Footwall mineralization is separate from previously reported mineral resources in the open pit Maybrun Zones.
The trend and exploration approach at Atikwa Lake has historically been oriented and directed on a 1400m long gold and copper signature that generally strikes northwest to southeast, predominately consisting of basalt lava flows (Maybrun Zones). The new altered andesitic Footwall Zone discovery, and drilling completed 600m to the north in hole AT-11-03, now suggests several east-west orientations for at least 4 areas to be tested under the current exploration program.
The second hole of the program (AT-11-02) was drilled (north-south) perpendicular to the projected east-west trending strike of an IP anomaly within the Footwall Zone. The strike length of this mineralization and anomaly is not yet known but could extend across the better part of the Atikwa Lake property in this area for up to 800m. This may also be the case for the other three east-west trending exploration targets on the property as noted above.
The Footwall Zone, and higher grade components therein, are wide open to depth from about 120m deep vertically and onward. Parts of the Footwall Zone have been noted along a north south orientation for at least 500m. These Archean-Proterozoic type units can extend for several thousand meters in depth. In addition, the recently discovered Footwall gold and copper mineralization may be distal to the main mineralizing event, fault or structure, which has not yet been observed in drill core. Deeper drilling in the areas of AT-11-01 and AT-11-02, along with drilling on strike in an east-west orientation on the 4 new target areas is strongly recommended by the Qualified Persons on the project. A revised and expanded exploration drill program will be announced in the near future with drilling expected to continue by the end of August, 2011.
