1950: J.H. Kolak staked the claims and transferred them to J.L. MacDonald. An option agreement was signed with Central Manitoba Mines Ltd. 1950-51: Central Manitoba Mines carried out a magnetic survey, trenching, and drilled 24 X-ray holes (1226 m). 1958-62: J.L. MacDonald carried out trenching. 1963: Delnite Mines Ltd. completed 8 drill holes (877 m) on the west end of the island. 1983: Golden Range Res. completed 5 X-ray drill holes (177 m). 1984: Mid Canada Exploration completed a magnetic and VLF survey. 1990: Chester Kuryliw mapped and sampled the island and completed one drill hole. 2003-2005: Prospectors Glatz and Riives staked the majority of the island prospect previous showings and the shoreline. Ontario Exploration Corp. optioned the property and completed reconnaissance and trench scale mapping. 2006: Ginguro Exploration completed a program of line-cutting, magnetic and Induced Polarization surveys over 17 line-kilometres. 2007: Ginguro Exploration completed a program of trenching over surface showings. 2008: Between April and July Giguro drilled 12 holes over a 1.65 km strike length totaling 3033 m with holes ranging between 92 to 308 m.

04/30/2020 (T Pettigrew) - Neepawa Island lies on the northwestern side of the zone of deformation associated with the northeast-trending Ruby Island, East Bay and Twinflower Faults. Within this deformation zone, there appears to be a large scale "Z" fold with the southern half of the fold lying between the East Bay and Twinflower Faults. The northern half of the "Z" fold is not well defined, however, mapping by Ginguro on Neepawa Island suggests that within the central part of the island an early foliation S0 and/or S1 trends about 160° and dips vertically. The dominant foliation mapped by Ginguro trends approximately 050° and dips vertically to steeply north. This would be at least S2 and is parallel to sub-parallel to the two main faults to the south. As a result of these observed foliations, lithologic contacts between volcanic units are very difficult to determine. Taking into account these structural complexities, Neepawa Island contains two main lithologic domains, a northern one of strongly foliated intermediate to mafic metavolcanics and a southern one comprised of greywacke and slate. Within the property, felsic dykes of the quartz and/or feldspar porphyry type are present generally as small dyke-like bodies that parallel the foliation. They are commonly sericitized and may host veins and/or irregular masses of quartz. The metavolcanics and sediments are altered to greenschist facies grade of metamorphism (Assessment report 20000001180).

04/30/2020 (T Pettigrew) - DDH 224-6 returned assays up to 2.787 ppm Au over 1.3 feet (0.4 m) from a cherty tuff with quartz veining with up to 20% pyrite. DDH 224-5 returned assays up to 2.058 ppm Au over 2.0 feet (0.61 m) from an andesite tuff with a quartz-carbonate vein containing pyrite (Assessment report 52G13NW0017). Grab samples collected by Golden Range Resources in 1983 returned values of 0.166 oz/T Au, 0.195 oz/T Au, and 0.376 oz/T Au (5.16, 6.06, and 11.7 g/t Au) (Assessment report 52G13NW0005).
