1941: Frobisher Exploration staked the property and over the next several years carried out a plane table survey, geological mapping and diamond drilling in the area of the west zone. Drill holes completed in 1942 included 12 short holes totaling 819 m on the Shakespeare deposit. 1948: 3 DDH totaling 1,360 m. 1947: Falconbridge Nickel Mines Limited (“Falconbridge”) (now Glencore) acquired the claims from Frobisher Exploration, and commenced an exploration program. 1951: drilled 12 short holes totaling 1,892 m. 1985: 16 holes totaling 1,030 m were drilled. 1986: 4 holes totaling 1,617 m were drilled to test the deposit at depth and along strike to the southwest. Falconbridge decided that the project could not meet economic parameters to move the project forward. 2000-01: property was acquired by URSA Major through a joint venture with Falconbridge. URSA carried out digital compilation, geological mapping, sampling, and some limited geophysical surveys. 2002-12: URSA carried out an extensive amount of diamond drilling, ground and bore hole geophysics, surface trenching, geotechnical mapping probing, feasibility and base line environmental studies, public consultations and successful permitting. URSA Major carried out diamond drilling programs on the deposit from 2002-2006 and from 2010-2012. 2007: URSA Major took a 50,000 tonne bulk sample. 2008: URSA Major began pre-production mining. 2010: pre-production continued, with commercial production beginning on May 27. 2012: production was suspended on January 27. 2017: Magna Mining acquired the property. 2018: Magna conducted borehole EM surveys on 18 holes and drilled 13 DDH totaling 3740 m. 2019: Magna carried out sampling, stripping, and mapping. 2020: Magna carried out channel sampling.

Province: Southern
Sep 10, 2021 (Therese Pettigrew) - The Dunlop-Shakespeare-Baldwin-Porter Township area is located along the southern margin of the Superior Province of the Canadian Shield and has had a prolonged evolutionary history involving the interaction between three structural provinces including the Superior, Southern and Grenville. The area surrounding the Shakespeare property is predominantly underlain by units of the Huronian-aged Mississagi quartzite and gabbroic intrusions, which trend approximately north northeast and dip moderate to steeply north. In particular, the Mississagi quartzites dominate the north and south limit of the land package and are typically whitish, medium grained and uniform, with cross-bedding features providing way-up indicators.

Sep 10, 2021 (Therese Pettigrew) - The Shakespeare copper-nickel deposit is hosted within gabbroic rocks (Shakespeare Intrusion) of the Nipissing Intrusive Suites situated along the north contact between the mafic intrusive body which crosses the Property and quartzites of the Mississagi Formation. The Shakespeare intrusion is a differentiated gabbroic intrusive sill that occurs predominantly in the south to central portion of the Shakespeare property and is between 300-500 m wide, extending over a 14 km strike length. In cross-section, the intrusion has an arcuate profile in which the dip shallows with depth, from ~80° to 40° to the North (Armitage and Laporte, 2021). The intrusive sill is mainly dark-grey, fine grained and predominantly consists of gabbro. According to Sproule (et al. 2007), the intrusion can be subdivided into; 1) the Lower Group composed of unmineralized pyroxenite and gabbro and; 2) an Upper Group composed of mineralized melagabbro, quartz gabbro, and biotite quartz gabbro-diorite. The base of the Upper Group is the primary host for the sulphide mineralization in the Shakespeare complex. The presence of a chilled margin between the Upper and Lower Groups suggests that the Lower Group was partly crystallized as a second pulse of sulfur-saturated magma, (i.e., the Upper Group) entered the sill complex. Mineralized melagabbro dykes are also recorded intruding into the lower unmineralized gabbro/pyroxenite package of the Lower Group. This may represent feeder dykes to the overlying Upper Group or small injections of Upper Group material, cutting downward into the underlying Lower Group (Sproule et al. 2007; Dastil 2014). The entire intrusion has subsequently undergone greenschist facies metamorphism, likely associated with the regional Penokean orogeny (1900-1850 Ma) (Dastil 2014).

Sep 10, 2021 (Therese Pettigrew) - The Shakespeare intrusion hosts semi-massive to disseminated sulfides. Sulfides, including pyrrhotite, chalcopyrite, pentlandite, and lesser pyrite, are present throughout the intrusion in varying proportions, mostly in trace amounts. Significant accumulations are present as: 1) Disseminations of pyrrhotite, chalcopyrite, and pentlandite close to the melagabbro/gabbro contact, usually ~1 mm in size, typically comprising <1% of the rock; 2) Heavily disseminated to patchy net-textured (10-15%) pyrrhotite, chalcopyrite, and pentlandite, in rounded blebs that reach up to 2-5 cm in size, in the upper zone of the melagabbro; 3) Blebby pyrrhotite and chalcopyrite in the lower sections of the melagabbro and the base of the quartz gabbro. The sulfides have experienced variable degrees of deformation and recrystallization during metamorphism. They vary from pristine magmatic blebs, to recrystallized blebs, to stringers, the latter of which tend to be richer in chalcopyrite. Where the mineralization is proximal to shear zones that cross-cut the deposit, the sulphides are often sheared and attenuated. These sheared sulphides, together with the patchy-network textured mineralization, create an interconnectivity in the sulphides that allows portions of the deposit to be identified by remote electromagnetic (EM) geophysics surveys, a valuable tool in exploring for extensions to the deposit. The mineralized zones also contain abundant inclusions of quartzite, blue quartz eyes, and rare diorite. The total strike length of Shakespeare mineralization is approximately 1,700 m and the mineralization extends to a depth of ~550 m (open at depth). The deposit is subdivided into a West and East resource (Armitage and Laporte, 2021). According to assessment work data, the average grade of mineralization is about 0.4% Ni, 0.4% Cu, and minor vanadium, platinum, palladium, rhenium, and gold (Card et al., 1970).
