Exploration History

1860-1874 : Chaffey Brothers - -open pit 300 x 100 x 40 ft deep; 4,000 tons of ore were raised and 3,300 tons shipped to Cleveland ( and Pittsburgh). 1957-59 : New Mylamaque Exploration Limited (later New Mylanaque Mining and Smelting Limited - ground magnetometer survey and geological mapping , DD-44-18,901 ft., feasibility study. 1966 : Canadian Bechtel Ltd. - feasibility study, preliminary engineering studies, cost estimates and metallurgical tests ( for New Mylamaque Mining and Smelting Ltd.), arrangements for development fell through in 1969.

Lithology Comments

Sep 14, 2015 (A Wilson) - The titaniferous or deposit occurs within a body of gabbroic anorthosite aboue 1 mile long and 0.5 mi wide that extends northwest from the shore of Newboro Lake. The banded gabbroic body is almost surrounded by monzonite, which intrudes the gabbro in some places, but grades into it in others. This body is in contact on the east side with migmatite and intermixed granitic rock and schist. The ore bodies consist of irregular segregations of titaniferous magnetite in a coarse-grained, gabbro-gneiss. A magnetometric survey indicated the existence of a considerable quantity of ore to the south and southwest of the ore body, which was exploited by a pit 300 feet long and 100 feet wide.

Mineralization Comments

Sep 14, 2015 (A Wilson) - In general, in the Matthews orebody there is a central core of higher grade ore, from 200 to 300 feet wide and around 1,900 feet long,shown on the plans and sections. To the east of this higher grade central core the magnetite content of the gabbro falls rather rapidly. To the west of the central core, magnetite mineralisation giving a grade of 20% or more iron continues for 300 feet or more. The average iron assay from 43 drill holes was 29.00% to 32.00% Fe, 9.74% TiOz,1.03% S04 and 0.151% phosphorous. The Matthews iron-titanium orebody forms an arcuate oxide-rich zone within the central part of the intrusion that dips vertically to steeply to the west. Layering is well developed in the ore zone and is generally oriented parallel to the elongation of the intrusion. Mineralization consists of abundant ilmenite and ilmenomagnetite that may constitute up to 60% of the rock, the rest being mainly plagioclase and pyroxene. The oxides are concentrated within melanocratic layers in well layered gabbro and form an interlocking mosaic of fine (1-2 mosaic of fine (1-2 mm) grains surrounding silicate grains. Pyrite is a minor constituent of the ore and occurs as scattered small rounded grains enclosed by ilmenite or ilmenomagnetite. Mining operations date from 1860. During 1871 upwards of 4,000 tons of ore were raised,of which 3,300 tons were shipped via boat to Cleveland, Ohio. There is no information available concerning any operation subsequent to that time.


Sep 30, 2020 (Nazha Sabiri) - Samples of ore material from rock dumps were reported to contain 0.1% vanadium as V2O5 (Robinson 1922 ).
