EXPLORATION ACTIVITY:
Sage Gold Inc. (https://www.sagegoldinc.com) encountered additional high-grade nickel-copper-mineralized rocks over significant widths at the Jacobus property, northeast of Beardmore (News Release, Sage Gold Inc., July 24, 2007). The highlights are as follows:
Hole-11 - 2.12% Ni and 1.02% Cu over 6.6 m within a broader zone of 0.90% Ni and 0.55% Cu over 21.4 m
Hole-12 - 0.93% Ni and 0.62% Cu over 7.3 m within a broader zone of 0.68% Ni and 0.52% Cu over 26.2 m
Hole-13 - 0.91% Ni and 0.79% Cu over 10.3 m within a broader zone of 0.61% Ni and 0.53% Cu over 20.6 m
Hole 7 was drilled as a vertical hole in the down-dip section of the zone but did not intersect the mineralized gabbro; the hole deviated from the intended target. However, this hole intersected a pyritized carbonate-rich section of chloritic tuff that yielded 15.15 g/t Au over 0.73 m. This gold-bearing horizon represents a new zone of mineralization that is not related to the nickel-copper mineralization within the gabbro.
The mineralized zone which starts at the surface can be traced down dip for 580 m. It is open laterally and at depth. The program was successful in confirming some of the historical results and also in extending the zone. Sage’s drill program planned for the fall will test the lateral extent of the mineralization and trace the zone further down-dip. Holes 11 through 14 were drilled in the up-dip section of the zone in order to confirm certain historical drill holes. The results correlate with the historical results and suggest that there is a higher-grade core to the zone which can be traced down-dip. Hole 6 yielded 0.95% Ni and 1.16% Cu over 11.45 m (ibid, June 14, 2007) and likely represents the down-dip extension of the higher-grade core. Holes 1 through 5 and 14 intersected lower-grade mineralization in the up-dip section of the zone. Holes 8, 9 and 10 deviated outside the zone and did not intersect the intended target.
The Jacobus prospect consists of a series of high-grade lenses that are aligned and form a mineralized zone within the Pinel Lake intrusion, a layered sill-like body composed predominantly of gabbro and quartz-rich leucocratic gabbro with minor pyroxenite and anorthositic gabbro. The zone varies in thickness from 6 to 25 m and has been tested down-dip from surface to about 580 m. The zone extends for 115 m laterally near-surface and has not been fully tested in the down-dip section. The mineralization includes disseminated sulphides, massive and net-texture sulphides and most importantly, a distinctive breccia with greater than 40% sulphides and angular and rounded fragments of anorthositic, gabbroic, pyroxenitic and volcanic material up to 20 cm in diameter. The majority of the fragments appear to be locally derived from gabbroic wall rock. However, the presence of pyroxenitic fragments suggests that at least some of the fragments were derived from an ultramafic part of the intrusion or from a magma chamber in the lower crust. Based on previous studies and preliminary current work, the deposit has a simple mineralogy of pyrrhotite, pentlandite and chalcopyrite with minor magnetite and pyrite.
