Jul 31, 2017 (A Wilson) - Silver was produced from the Seneca-Superior Lease from 1912-1916. A total of 5,527,597 oz. of silver was mined from this lease. A total of 27,303 lbs. cobalt; and 918076 oz. silver; were recovered between 1908 and 1967. Most of the early work done on this property was to explore extension of veins or vein system occurring on the Nipissing properties to the west. Although ore was found in the easterly extensions of the vein systems occurring on RL.404, the total production on the Peterson Lake ground was very much smaller. Two sets of veins occur on the Peterson Lake ground - one of these strikes westerly and is possibly related to Keewatin structures, particularly the position of inter-flow sedimentary bands. The other set has a northeasterly strike and has a parallelism to the axis of the Peterson Lake diabase basin, To this set the writer would assign the Worth vein of the Seneca-Superior Lease and others in Peterson Lake, The vein structures in this set appear to be fractures and not faults; they are discontinuous and irregular. The productive horizon in the north arm of Peterson Lake was the Keewatin in the vicinity of the Keewatin - Nipissing contact. Whether the vein structures stopped near this contact or continued into it but were barren is not clear but the latter appears more likely.

Jul 31, 2017 (A Wilson) - Keewatin rocks and Cobalt sediments are intruded by Nipissing diabase sills. The diabase forms the west limb of the southwest trending Peterson Lake Diabase Basin. The Nipissing diabase sill intruded the Huronian and pre-Huronian rocks on the Peterson Lake property in such manner that a wedge shaped mass of Cobalt Series sediments was left below the bottom contact of the sill; this contact does not follow the Cobalt series-Keewatin contact nor is it approximately parallel to it. The diabase on the property is on the southwest limb of what the writer calls the Peterson Lake Basin. At Peterson Lake No. l shaft the Cobalt series is 185 feet thick and this is nearly its original thickness below the sill before erosion of the latter at this place. In plats of the diamond drilling done by Car-Pete Lease and kindly made available by A. L. Barry, who logged the core, the presence of a band of bedded greywacke up to19 feet thick in the basal conglomerate is shown. Below this band the conglomerate contains boulders of Keewatin rock predominantly; above the band red Lorrain granite boulders predominate. Silver-bearing veins occur in two sets; one of these strikes west and follows Keewatin interbanded chert; the other strikes southwest parallel to the axis of the Peterson lake Basin. Production is mostly restricted to the vicinity of the Keewatin-Nipissing contact. Base metal mineralization such as chalcopyrite and niccolite occurs as disseminated sulphides in the Keewatin rocks.
