In the final completed drill hole of the Program (BA-13-77), an initial test of a new, high-priority conductor identified by the DEEP EM survey was achieved by reorienting a previously planned hole at the Thunder Zone (Figure 1). Six holes drilled by Cameco in 1990-1991 in this area intersected several narrow intervals of low-grade mineralization. The re-oriented hole BA-13-77 intersected 1.10m of copper-rich massive sulphide mineralization starting at 356.96m downhole (205m vertical depth) at the top of a broader interval of semi-massive sulphide. Assays for the hole returned 4.08% Cu, 0.43 g/t Au and 27.0 g/t Ag over 3.66 m, including 10.60% Cu, 0.70 g/t Au and 62.5 g/t Ag over 1.10m.
Massive sulphide mineralization in hole BA-13-77 is comprised of chalcopyrite (up to 40%)-pyrrhotite-magnetite-arsenopyrite-pyrite-sphalerite hosted within andalusite-chlorite-sericite altered felsic volcanics (Figure 3). Alteration intensity and mineral assemblages are similar to those at McIlvenna Bay.
A borehole electromagnetic survey was conducted on hole BA-13-77 and both the borehole and DEEP EM geophysical survey data is currently being modelled and interpreted by Foran's geophysical consultants with the objective of better quantifying the potential size, strength and orientation of the conductor associated with the Thunder Zone.
Drill holes BA-13-74, -75, -76, and -78 tested the B2 Zone, situated immediately southeast of the Thunder Zone (Figure 1). B2 Zone massive sulphide mineralization is hosted within an interpreted stratigraphically lower interval below the Balsam Zone. Drill testing of the B2 Zone by previous operators returned 3.32% Cu and 1.10 g/t Au over 3.32m in hole 96-BAL-60.
Highlights from the B2 Zone in the Program include:
-- Hole BA-13-74: 1.29% Cu, 0.28 g/t Au and 12.3 g/t Ag over 4.56m, including a massive sulphide interval of 3.97% Cu, 0.84 g/t Au and 39.1 g/t Ag over 0.85m-- Hole BA-13-78: 8.40% Zn, 0.28 g/t Au and 12.6 g/t Ag over 3.21m of semi- massive sulphide, followed approximately 3m further down-hole by massive sulphide with 6.66% Zn, 0.27 g/t Au, 10.6 g/t Ag over 0.78m-- Hole BA-13-75: copper stockwork mineralization with 0.47% Cu and 0.30 g/t Au over 6.31m, including 1.34% Cu and 0.73 g/t Au over 1.87m-- Hole BA-13-76: massive sulphide grading 4.11% Zn over 2.23m.
The mineralized intervals in the B2 Zone consist of sphalerite-chalcopyrite-pyrite-pyrrhotite massive sulphides hosted within felsic volcanics and underlain by copper stockwork. Within the B2 Zone, a lateral transition from copper-rich mineralization in the south in BA-13-74 to zinc-rich mineralization in the north is indicated. Results of 2013 drilling suggest shallow depths to B2 Zone massive sulphide with at least 400 metres of strike length and open to the northwest beyond BA-13-78.
Holes BA-13-72 and -73 were drilled to test the up-plunge, southeast strike extent of the Balsam Zone near surface, where the 1984 discovery hole for this area intersected 3.19% Cu, 3.30% Zn, 3.60 g/t Au and 52.48 g/t Ag over 6.50m in hole BAL-11.
Hole BA-13-72 returned 2.28% Cu, 1.3 g/t Au and 13.8 g/t Ag over 0.43m; no significant values were returned from hole BA-13-73.
Holes BA-13-70 and -71 were drilled to test the southeastern strike extent of the B4 Zone, where 1996 drill hole BAL-96-53 intersected multiple narrow intervals (0.61 to 1.27m) of zinc mineralization within a 49m section of altered felsic volcanics with grades of trace to 3.91% Zn.
