The Rocky Brook project includes four claim blocks that cover 1,586 hectares in northern New Brunswick (approximately 45 km northwest of Bathurst). Lacana Mining (later named International Corona) discovered mineralization on the current claim block 10024 in the 1980’s, with up to 18.0 metres grading 52 g/t Ag and 0.17 g/t Au that includes 3.4 metres grading 165 g/t Ag and 0.38 g/t Au in drill hole RB-87-02. Lacana carried out VLF-EM, magnetic, IP, and soil geochemical surveys; however, trenching and diamond drilling by Lacana was largely focused on a 1.5 km strike length whereas the current property covers a potential 10 km of the host structure. Highlights of historical drilling and more detailed drill results are shown in attached diagrams. Government geological mapping indicates the claims are largely underlain by felsic volcanic rocks; however, more detailed mapping by Lacana also shows mafic volcanics, gabbro and sedimentary rocks. In 1996, a prospector who had earlier worked on the property for Lacana, reported results from a trench excavated by Lacana in 1989 that had not previously been submitted in reports of work and included several significant grab sample assays up to 223 g/t Ag and 1.73 g/t Au. The location of this trench is approximately 700 metres east of the drilling by Lacana and to the south of the projected main mineralized structure, possibly indicative of another mineralized structure. Very limited work has been reported on claim blocks 10024 & 10382 since the work done by Lacana in 1992.
Claim 10606 was staked to acquire the Upper McNair Brook Ag-Au occurrence that is described in the New Brunswick mineral occurrence database as follows: “Unpublished correspondence from 1938 between W.J. Wright and prospectors makes reference to "...silver leads..." assaying between 69.3 and 857 g/t and 0.34 to 1.7 g/t Au near the falls on Upper McNair Brook (Burton, 1987). The mineralization is associated with a rusty northeast trending shear zone in what is described as fine-grained basalt. Mineralization also occurs in a 1.2 m (3.9 ft) vertical quartz vein (Wright, 1939). The property was staked by Restigouche Mining Syndicate, but no information is available on their work. Alcock (1941) describes sulphide mineralization in quartz veins, seams, and as disseminations in mafic volcanic rock. A grab sample assayed 91.2 g/t Ag. Burton sampled silicified volcanic rock and sedimentary(?) breccia in the vicinity of the old showing in 1987. The samples contain Cu (up to 880 ppm), Pb (3800 ppm) and Zn (1100 ppm) and were weakly anomalous in Au-Ag-As-Sb-Bi-Mo. The mineralization consists of disseminated chalcopyrite, galena, pyrite, and hematite. Burton describes the rocks as being very similar to those found at the Rocky Brook Au-Ag occurrence”. No significant work has been filed to follow-up the Upper McNair Ag-Au occurrence.
In addition to the mineral occurrences identified on the property, the claims were staked to cover anomalous silver identified in a government stream sediment survey that includes significant silver values on and adjacent to claim blocks 10024 & 10606. Since acquiring the claims, limited soil sampling has been carried out that identified a significant silver anomaly on claim block 10606 trending southeasterly over 0.5 km with up to 7.7 ppm Ag. The soil anomaly remains open to the northwest and southeast and trends toward a soil anomaly in the eastern part of claim block 10024 where values range up to 4.1 ppm Ag.
