Drill hole NKDDH031, an approximate 50m step-out down dip of NKDDH029, returned two alteration zones of 10m scale. The shallower alteration zone hosts poorly developed Apankrah Shoot style mineralization, carbonate, pyrrhotite, pyrite and silica, and returned 4.0 m of 3.28 g/t Au, including 1.0m of 6.94 g/t Au. Of importance was the observation of a number of low to moderate angle fault zones indicating that the area is geologically more complex than initially interpreted.
Drill hole NKDDH032, an approximate 50m step-out down plunge of NKDDH029 (100m down plunge step-out from NKDDH022), returned a single poorly developed alteration corridor of roughly 20m width hosting weak mineralization returning 5.34m of 0.3 g/t Au. Similar faulting to that observed in NKDDH031 was also observed in this drill hole.
Drill hole NKDDH033 was completed between NKDDH022 and NKDDH030. A number of alteration zones were intersected ranging from 1.1m to greater than 15m in core length. The largest alteration zone hosted Apankrah Shoot style mineralization returning 7.0m of 0.64 g/t Au. Given the coarse nature of the gold observed in the Apankrah structure it can be expected that some intercepts, although exhibiting the expected style of mineralization, may return values lower than anticipated.
These drill hole intercepts together with previously released NKDDH009ext, 010, 016, 017, 018, 022 and 028 intercepts are beginning to better define the Apankrah Shoot; a steeply plunging high grade shoot with a strike length averaging over 100m and increasing with depth and a down plunge/dip extent of over 300m which is open to the west and at depth (see Figure 2 at http://www.castlepeakmining.com/i/pdf/2013-1-14_NR.pdf). This high grade shoot is located within the auriferous Apankrah structure which has a known strike length of greater than 250m and is open in all directions.
The mineralized structure is defined by an assemblage of silica, carbonate, pyrrhotite, pyrite and gold with the highest grades correlating directly to the presence of visible gold. This structure, along with the parallel Nana structure and third un-named structure, are hosted in a package of poorly understood Birimian mafic metavolcanic rocks and are currently interpreted to be roughly parallel to flow contacts.
