Point Location Description: Collar of hole #118-54-1 drilled by Dominion Gulf in 1954.
Location Method: Data Compilation
Access Description: Presently the closest trail is an ATV trail following the old road from the Nemegos Station to an old fire tower which passed to the west of Lackner Lake. This is a three kilometre traverse from the prospect. During the summer of 1994 a new logging road was being pushed south from the northern boundary of the township. This road at present is still at least 5km from the prospect. The old tote road which connected the Halcrow Swayze deposit with the village at Nemegos passes just south of the prospect.
1951 Dominion Gulf staked an airborne magnetic and radiometric anomaly adjacent to ground held by Nemegos Uranium. Follow-up ground work in the next year consisted of a geological reconnaissance and a ground magnetic survey. This work outlined three phosphate zones within a nepheline syenite. In 1954 three holes were drilled to test the phosphate zones and one consisted of 60m (200') of massive magnetite apatite. 1955 Apamag Mines Ltd over a two year period drilled five holes on a group of surrounding claims and intersected disseminated apatite and magnetite in mafic syenites and nepheline syenites. 1958 Falconbridge Nickel Mines staked the ground previously held by Dominion Gulf with the objective of evaluating primarily the nepheline - nepheline syenite and apatite content. A secondary evaluation of the magnetite, and pyrochlore mineralization was also done, all with the hope of integration with operations in Sudbury. The nepheline was initially being sought as soluble source of Al2O3 for metallurgical extraction but was later regarded as a ceramic product. Ground work started in 1959 with a ground magnetic survey, geological mapping and a diamond drill program. The 750m drill program (2500') tested various anomalies with a series of short holes. From this it was concluded that 1.8 million tonnes of 3.7% phosphorous and 7.87% soluble Al2O3 material existed above the 150m level in the prospect documented here (2 million tons, 500') and 3.6 million tonnes of ceramic grade nepheline syenite existed apparently associated with the same zone (4 million tons). A sample of the nepheline syenite was shipped to American Nepheline for bulk testing but the results are unknown. Detailed petrographic work was also carried out. 2009: Rare Earth Metals Inc.- AMAG, ARAD. 2014: International Explorers and Prospectors Inc. – Assays, Anlys, GL, RAD, Samp; Gold Crossing Ltd.-Assays, GL, RAD, Samp.

Dec 07, 2005 (S Fumerton) - The mineralization tends to be located near a brecciated igneous contact.
Dec 07, 2005 (A Wilson) - The mineralization is hosted in a very fine-grained black syenite with approximately 40% feldspar with hornblende, augite as the main mafic minerals. Some feldspathoid is reported and abundant magnetite is disseminated in the rock. The deposit is associated with the Lackner Lake alkalic complex. The complex consists of peripheral and core nepheline syenites separated by a partial ring of alkalic mafic rocks (ijolite and malingite). Dikes of magnetite and apatite cut both the mafic and syenitic phases of the complex. Lamprophyre dikes also reportedly cut the complex. The Lackner Lake complex is enclosed within the gneissic rocks of the Kapuskasing Structure.

Dec 07, 2005 (S Fumerton) - The apatite mineralization is hosted in a very fined grained black syenite with approximately 40% feldspar with hornblende, augite and biotite as the main mafic minerals. Some feldspathoid is reported and abundant magnetite is disseminated in the rock. The nepheline syenite is coarse grained with zoned subhedral apatite, partially surrounded by orthoclase laths both of which are replaced in part by nepheline. Mafic minerals are interstitial and consist of clinopyroxene, biotite and magnetite. Detailed petrographic work has been published by Parsons (1961), Hodder (1958) and Sage (1983).
Sep 12, 2018 (A Wilson) - The nepheline syenite is coarse-grained with zoned subhedral apatite, partially surrounded by orthoclase laths, both of which are replaced in part by nepheline. Mafic minerals are interstitial and consist of clinopyroxene, biotite and magnetite. Closer to the mineralized zones, the rocks are finer grained, richer in sodic pyroxenes and have a granoblastic texture. The composition of these rocks is mafic nepheline syenite or malingite.

Dec 07, 2005 (S Fumerton) - Apatite is the main economic mineral and is disseminated in the matrix of the black syenite. The general distribution of nepheline proved difficult to evaluate macroscopically in drill core and was inferred from alumina solubility analyses.

Geologist: W Savage
Notes: Several days were spent by the writer on the Multi Minerals property in McNaught township in October. A brief visit was made on the morning of October 15th to the Dominion Gulf Camp on the west shore of Lackner Lake. The original group, consisting of 30 claims in the centre of the SW quarter of Lackner township was staked by Dominion Gulf Co. in the Fall of 1951. The discovery of radioactive magnetite - apatite deposits on the Nemegos Uranium property in the adjoining township of McNaught aroused interest in the area. Diamond drilling of the (magnetically) anomalous areas on the hill for possible ore bodies of magnetite-apatite was recommended by Ratcliffe in his report of December 1st, 1952 but no further work was done on the property until the discovery of columbium associated with the magnetite-apatite deposits again focussed attention on the area in 1954. At the time of my visit the first hole of a proposed diamond drilling programme had been started, but was still in overburden. [ PRECIS ]
