Point Location Description: The collar to hole #10 drilled by M. Silverman in 1954.
Location Method: Data Compilation
Access Description: Though the drill set up is near the old wagon road between Nemegos and the Halcrow Swayze mine, the closest passable road is now the road to the Multi Minerals workings over 2 km away.
1954: M. Silverman carried out a ground magnetic survey in conjunction with a geological reconnaissance mapping program over a large claim group east of the Multi Mineral deposits. 1959: M. Silverman resumed a diamond drilling program and an additional 18 holes were drilled.

Province: Kapuskasing Structural Zone
Geological Age: Mesoproterozoic Geochronological Age: 1078 +/- 7 MA Geochron. Age Ref.: OGS STUDY 32, P 32
Dec 07, 2005 (A Wilson) - The Lackner Lake complex consists of peripheral and core nepheline syenite separated by a partial ring of mafic alkaline rocks (ijolite and malingite). Magnetie-apatite dikes crosscut all phases of the complex. Lamprophyre dikes also have been reported to cross cut all rock types. The intrusion is enclosed within the gneissic rocks of the Kapuskasing Structural Zone.
| Rock Type | Rank | Composition | Texture | Relationship | Syenite | 1 | Nepheline Syenite | Host |
|---|---|---|---|---|
| Ijolite | 2 | Host |
Dec 07, 2005 (S Fumerton) - The host rock to the mineralization is reported as a coarse nepheline syenite with varying amounts of magnetite. Regional geological descriptions are given by Parsons (1961) and Sage (1983).
Dec 07, 2005 (A Wilson) - The mineralization is reportedly hosted within a coarse-grained nepheline syenite with varying amounts of magnetite. The magnetic anomalies are caused mostly by magnetite bands and veins.

Dec 07, 2005 (S Fumerton) - Some massive magnetite seams are reported.
Sep 12, 2018 (A Wilson) - The Nb analyses from split core ranged up to a maximum of 0.29% Nb2O5 over 5 feet, but the more mafic foliated rocks generally ranged from 0.07 to 0.14% Nb2O5 (Study32).
Jun 07, 2023 (Q Unknown) - In 1954, M. Silverman carried out a ground magnetic survey in conjunction with a geological reconnaissance mapping program over a large claim group east of the Multi Mineral deposits. This work identified a number of magnetic anomalies hosted in nepheline syenite and eleven holes were drilled to test these anomalies for niobium mineralization in the same year. Reportedly values of 0.29% Nb2O5 were obtained but from which hole is unknown. Hole #9 intersected nepheline syenite with magnetite locally forming up to 45% of the rock and also contained a brown garnet which may be pyrochlore. Hole #10 intersected local heavy magnetite mineralization plus scattered sodalite. In 1959, M. Silverman resumed a diamond drilling program and an additional 18 holes were drilled. These holes were concentrated along the southern ring of the alkalic complex and three holes were spotted to test the south flank of the anomaly initially tested with hole #10. Other drill hole concentrations were along the fault trending southwest from the complex, the fault trending northeast from the complex, and along the eastern margin of the complex. Most of these holes were abandoned in deep overburden and no assays are reported for those holes that reached bedrock.
