Point Location Description: Occurrence 5 on map P.2607
Location Method: Conversion from MDI
Access Description: The iron range is most easily accessible by air from Wawa. A float equipped aircraft can land on Finger (Cline) Lake in north central Corbiere Township and the outcrops can be accessed by a short (700 m) traverse from the south east end of the lake. Alternatively, the iron range can be accessed by overland traverse from the Alden siding on the ACR rail way line, a distance of approximately 4 km.
The date of the discovery of the iron range is unknown but extensive trenching along the iron range was conducted by James Cline before 1947. In 1953, the iron range was mapped by the Jalore Mining Company. 1972; Getty Mines Limited prepared a geological map of the Cline Lake, Big Lake and Sheldon Lake Iron Ranges. Soil geochemical surveys and a ground VLF survey was completed in the area. Three diamond drill holes were completed (590 feet). DDh G)-4 returned anomalous Cu and Zn values.

Dec 07, 2005 (A Wilson) - The Cline Lake Iron Range is presumed to be a structural repetition of the Big Lake Iron Range. It is a poorly exposed Michipicoten-type iron range occurring at the break between mafic and felsic volcanism of cycles one and two. The south end of the Cline Lake Iron Range may correlate with the north end of the Big Lake Iron Range if the shearing and stacking took place before the folding. The range extends from Finger (Cline) Lake in the NW to a small, unnamed lake approximately 2 km to the SE.

Dec 07, 2005 (A Wilson) - The iron range has been described as coarse pyrite disseminated in chert adjacent to a banded chert horizon. The iron range is south facing and is enclosed by carbonate and chloritoid altered massive and tuffaceous intermediate metavolcanics on the north side, and massive to strongly foliated, carbonate and chloritoid altered mafic metavolcanics on the south side.

Dec 07, 2005 (A Wilson) - Anomalous Cu and Zn soil geochemical anomalies have been found in the area of the iron range. Some chalcopyrite-bearing fractures have been found and have returned assays of 0.55% Cu and 0.64% Zn. One diamond drill hole (GO-4) drilled by Getty Mines returned Cu assays between 0.01% and 0.21% and Zn assays from 0.02% to 0.47%. Thin graphite, pyrite and magnetite bands have been reported throughout the formation but have not been substantiated by the writer.
Dec 07, 2005 (A Wilson) - Carbonate and chloritoid alteration is apparent in the metavolcanic rocks enclosing the iron range. The carbonate alteration is secondary.
