Size: approximately 1,651 ha in area and comprises 102 contiguous exploration claims
Target: orogenic, auriferous quartz veins
Access: Paved Highway and Logging roads
- Forest Hill is located approximately 160 kilometers (km) northeast of the city of Halifax, and 40km southeast of the town of Antigonish
In February 2020, Aurelius Minerals Inc. (Aurelius) acquired 2672403 Ontario Ltd. (property owner) from Sprott Resource Lending. The project can be accessed via a network of all weather logging roads 5km from the provincial highway. The property is serviced by provincial grid power. Gold was discovered on the Property in 1893 and between then and 1916, approximately 27,000 ounces of gold were produced from various quartz veins within the Property. A total of 334 surface and underground drill holes were completed for 34,772 m of drilling on the project. Forest Hill has a current resource of ~281,000 ounces of gold indicated and inferred @ 7.1g/t.
A cutoff of 2 g/t gold was taken as the base case and is shown. Both capped (110 g/t Au) and uncapped grades are shown; the uncapped grades are included to illustrate the impact of capping.

Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that all or any part of mineral resources will be converted to mineral reserves. Inferred Mineral Resources are based on limited drilling which suggests the greatest uncertainty for a resource estimate and that geological continuity is only implied. Additional drilling will be required to verify geological and mineralization continuity and it is reasonably inferred that most of the inferred resources could be upgraded to indicated resources. Quantity and grades are estimates and are rounded to reflect the fact that the resource estimate is an approximation.
The Property is primarily underlain by a sequence of metagreywacke and subordinate, interbedded slate belonging to the Goldenville Group that is approximately 1,500 meters wide (north-south). These rocks have an east strike and are bounded to the north and south by slates of the Halifax Group. This package of rocks has been folded into an anticline that is overturned and dips steeply to the north. Devonian-age granitoid intrusives occur immediately to the north and within approximately one kilometre to the south of the Property and have caused amphibolite-grade contact metamorphism as evidenced by the presence of staurolite, andalusite and garnet. Emplacement of the granitoid batholiths was accompanied by the intrusion of numerous pegmatitic dikes into the Meguma sedimentary rocks within the Property.
Quartz veins developed during folding and are concentrated on the south limb of the anticline; those of economic interest are located within approximately 200 meters of the anticlinal axis although veining extends for up to 500 meters to the south of the fold axis. Quartz veins also occur on the north limb of the anticline, but none has been found to be sufficiently mineralized to warrant systematic exploration and therefore these veins are essentially undocumented.
The Property is cut by faults, predominantly with a northwest strike characteristic of the eastern half of Nova Scotia, but northeast-trending faults have been documented as well, and both sets offset the quartz veins. Offsets are on the order of several tens of meters. Most of the exploration and development of underground workings has taken place between the two northeast-trending faults.
The Property contains auriferous quartz veins; most are bedding-parallel but cross-cutting veins have also been reported. Vein thicknesses range from several centimeters to decimeters. Gold most commonly occurs in native form as flakes and grains within quartz veins and on the margins of veins immediately adjacent to wallrock. Arsenopyrite, pyrite and pyrrhotite have been reported together with minor occurrences of galena, sphalerite, chalcopyrite tin, tungsten and stibnite. There appears to be a spatial but non-linear relationship between gold and arsenopyrite and to a lesser degree, between gold and galena.
Gold occurs within “shoots” from seven to 30 meters in height and several hundred meters in strike length within a given vein. These zones commonly have the same plunge as the axis of the anticline and are auxiliary or parasitic folds developed on the flanks of the principal anticline and empirical evidence indicates these shoots relate to the intersection and overlapping of “angular” veins with bedding-parallel veins. Angular veins are roughly strike-parallel and generally discordant to bedding. Locally they intersect and follow bedding-parallel veins before exiting on the stratigraphically opposite side where they maintain a similar discordant attitude. Coarse gold and high grades occur in the overlapping intervals resulting in the observed ore shoots. These secondary folds typically occur in en-echelon fashion within a given vein, as well as in adjacent veins.
Auriferous quartz veins of economic interest are all located on the steeply-north-dipping (70° to 80°), overturned, south limb of an east-trending anticline within 250 meters of the anticlinal axis. Within that 250-meter interval, a central 50 to 60-meter-wide interval of interbedded metawacke and schist termed the Schoolhouse sequence contains the Schoolhouse 1 through 6 stratiform veins or vein packages which were historically the most productive and were the primary subject of more recent bulk sampling programs. Veins are boudinaged, are generally from five to 15cm thick and some are persistent along strike and down-dip for hundreds of meters. Several of these veins have been traced for over 500 meters along strike and the enclosing stratigraphy has been traced along strike for at least 2,000 meters.
The Company has a 100% interest in the property through its wholly owned subsidiary Aureus Gold Inc.
