In May 1995 Pacific Mariner Exploration carried out a small drilling program on its properties in Strathy Township to estimate the likelihood of base metal deposits.
A 215 m (705 ft) hole was drilled under Net Lake in Temagami North, but its collapse prevented the survey's completion.
As a result, little is known about its geophysical features.
Most of the property was influenced by Net Lake and included ten adjacent mining claims.

At least five explorations took place in the Strathy Township property before 1995.
In 1934 Strathy Basin and Erie Canadian Mines conducted prospected sections of the 1995 claim block.
A 21.2 m (70 ft) wide rusted zone within a dike was announced as containing values of $7.50 combined gold, copper and nickel.
Little work has been completed in this area.
In 1959 and 1960, Goldfields Mining conducted a basic airborne electromagnetic survey and magnetic survey over the property.
Several holes were drilled and intersected mostly mafic to intermediate volcanic rocks and areas of stringer sulfides with pyrrhotite, pyrite and some chalcopyrite.
No assays were reported.
In 1970 E. L. McVeigh occupied a section of the property, including the area that was once owned by Strathy Basin Mines.
McVeigh conducted geophysical surveys over Strathy Basin's mineralized zone and announced no conductors.
From 1974 to 1975 Vale Limited owned an extensive section of the Strathy Township property.
They conducted magnetic and electromagnetic surveys, as well as mapping and drilling.
Vale announced that they intersected mineralized sulfide zones ranging from 3.1 m (10 ft) to 45.6 m (150 ft) thick.

In 1952 Rib Lake Copper Mines explored areas adjacent to Whitney Lake and between Whitney Lake and Rib Lake, by creating trenches and carrying out diamond drilling.
Nickel was discovered with widespread pyrrhotite in sheared mafic rocks.
Gold mineralization was discovered with pyrite in slightly siliceous tuff.
The highest assessment was 1.30 oz (37 g) of gold per ton and 0.99% of nickel over 1.8 m (5.9 ft), both from the same zone.
Detailed work did not occur in the Rib Lake area of southern Gillies Limit Township and northern Best Township until 1968, when mapping took place, but it is unclear whether volcanic rocks in the Rib Lake area are part of the TGB, as they have not been mapped in any detail.
With the existence of Early Archean age tholeiitic and/or calc-alkaline mafic to intermediate volcanic rocks, they may represent a minor continuation of the belt, which is located about 6 km (3.7 mi) to the southwest.
Small intrusions and pyroclastics of mafic composition are also present in the area.
In 1956 Silanco carried out geophysics south of Whitney Lake.
In 1964 Nickel Rim Mines Ltd. had a greatest result of 1.30 oz (37 g) of gold per ton.
The exploration and mining activity south of Gillies Limit Township observed nickel, copper and platinum group metals at Cuniptau Mine and gold, silver and copper at the Big Dan and Little Dan mines.
