Resident Geologist District: Timmins
NTS Grid: 41O14SE
Point Location Description: DDH #14 from company assessment files.
Location Method: Data Compilation
Access Description: Presently the easiest access is via the Lackner Lake logging road being constructed from highway 101. This road comes within 2km of the Portage Complex.
1951 John Chyka carried out a ground magnetic survey (dip needle survey) together with prospecting, stripping and three short diamond drill holes to test the magnetite zones. In the following year Mogul GM, initiated a geological reconnaissance of the property plus carried out a ground magnetic and radiometric survey. This work identified a number of magnetite zones up to 700m long together with some apatite and niobium zones. 1954 Chyka Mines, apparently a subsidiary of Mogul GM, drilled 28 holes to test the magnetic zones for the niobium mineralization. No assays from this work are on file. 2009 : Rare Earth Metals Inc.: AMag, ARAD. 2010: 607205 Canada Inc.: Assays, Pr, ARAD, 2016: Labelle, M.F.: Pr, Samp (T-6996).

Dec 07, 2005 (A Wilson) - The Portage Lake complex is a small subsidiary complex related to the Lackner Lake intrusion. It is composed entirely of alkalic mafic rocks (massive ijolite and ijolite breccia). It is situated just north of the north rim of the Lackner Lake complex. It is enclosed within the gneissic rocks of the Kapuskasing Structural Zone.

Sep 12, 2018 (S Fumerton) - The mineralization is hosted in the Hebden Lake or Portage Lake alkalic ring complex which is a small satellite complex adjacent to the much larger Lackner Lake alkalic complex. No details are given in drill logs or company records on file. Comments such as disseminated magnetite form up to 15% of radioactive greenstone within nepheline diorite. There are also comments in the drill logs such as sedimentary looking cross laminations resembling cross bedding.
Sep 12, 2018 (A Wilson) - The complex consists chiefly of ijolite. The ijolite consists of nepheline, pyroxene and minor amounts of titanite, magnetite, apatite, calcite and sulphides. It ranges from a fine-grained to very coarse pegmatite rock. Its contact with the surrounding gneiss is gradational; pyroxene, nepheline and minor titanite and calcite have formed in fractures and along the foliation of the contacting gneiss.

Sep 12, 2018 (P Bousquet) - A hand sample taken approximately 400 m away returned an assay with 1546 ppm total rare earth elements, and 428ppm Nb (See geochemistry entry).

Geologist: W Savage
Notes: A visit was made to the old Chyka camps at the east end of Portage (Hebden Lake). The writer was accompanied by G.E. (Red) Parsons, consulting geologist. The purpose was to examine diamond drill core. At the time of our visit rain started soon after we left the jeep and continued without let up all day. At the old Chyka camps no buildings remained standing. The cores from both the Chyka and Claymac drilling were still racked although the core shack had collapsed on top of them. We rigged up part of the core shack roof to work under and found the an old stove to keep us warm while we examined the core from a number of representative holes. We got back to the jeep before dark, thoroughly soaked, but luckily it had been a warm day for October. [ PRECIS ]

Geologist: P Bousquet
Notes: A visit was made in the area with Eric and Maurice Labelle. The writer was accompanied by E. Papanicolaou (Summer student). The purpose was to examine some properties in the area. The day was beautiful, but the main property targeted was not reached. However, a sample was taken at location E:343587 N:5299345. The sample was a pyroxene syenite, showing very large biotite booklets. The assay of that sample is shown in the geochemistry section.
