The Little River gold property is located approximately 20 km southwest of Bathurst in northern New Brunswick. Gold is considered the primary target on the property, although very high-grade massive sulphide boulders have also been found on the claims. The property is approximately 2 km south of the Middle River gold deposit where gold mineralization has been has identified over a strike length of 490 metres, with the best intersection grading 3.41 g/t Au over 17.6 metres, including an upper zone of 4.7 metres grading 7.49 g/t Au, and a lower zone of 1.7 metres grading 6.51 g/t Au. A 3-meter zone of quartz breccia containing pyrite and arsenopyrite was discovered in a trench on claim block 7727 with samples grading 0.85, 1.74 and 2.65 g/t Au. This is referred to in the NB mineral occurrence database as the ”Little River Smith” showing. Significant float occurrences have been identified with up to 15.9 g/t Au that are within 150 metres of the gold zone in the trench. The Little River gold property is available for option and includes seven claim blocks that cover 2,072 hectares. The claims are on Crown Land. Relief is low with elevation varying from approximately 210 to 260 metres above sea level. A major logging road passes through the east part of the property and other logging roads provide easy access to the claims.

Two short holes were drilled, attempting to undercut the gold zone in the trench, one of which intersected a 20 cm alteration zone with fuchsite and only resulted in 30 ppb Au; however, the holes would not have intersected the zone if it is dipping, even quite steeply, to the southeast (strike is assumed to be southwest, similar to Middle River gold deposit). A limited induced polarization survey was carried out on four short lines over the gold mineralized zone that identified chargeability and resistivity anomalies, some of which remain untested or unexplained. Soil surveys on the property indicate significant areas with anomalous gold values; however, very limited effort has gone into exploration for gold on the property. A report of work filed by Atlin-Ruffner in 1954 indicates drill holes in the west part of claim block 11164 intersected scheelite with 0.04% WO3 as well as zones of disseminated sulphide mineralization that may be gold-bearing; however, very limited assay data is available, and no gold assay data was reported.

Although gold is now considered the primary target on the property, historical work has largely focused on massive sulphide mineralization. The supergiant Brunswick No.12 volcanogenic massive sulphide deposit is located approximately 5 km southeast of the property. Very high-grade massive sulphide boulders have been found on the property ranging up to 1.37 g/t Au, 360 g/t Ag, 13.85% Pb and 8.01% Zn; the location of this boulder is not clear; however, the locations of other high grade massive sulphide boulders are shown in appended figure. A significant trenching program had been carried out by a previous claim owner to locate the source of the massive sulphide boulders. That trenching program identified semi-massive to massive pyrite with no significant base or precious metal values. The trenching program did not locate the source of the high-grade massive sulphide boulders but resulted in discovery of the Little River Smith gold occurrence. Massive sulphide deposits in the region (i.e. Bathurst Mining Camp) are related to Ordovician felsic volcanic rocks; however, no outcrop of felsic volcanic rock has been found on the property and the Au-Ag-Pb to Zn ratios of the high grade massive sulphide float found on the property are not typical of the region’s massive sulphide deposit, possibly indicating the boulders may not originate from volcanogenic massive sulphide mineralization typical of the region.
