The Fram North is a lead showing located 10 kilometres southwest of Mount Sylvia in the mountainous Muskwa Ranges of the Northern Rocky Mountains (Assessment Report 2875, Map 1). The main mineralization in this general locality is covered by the Fram copper showing (MINFILE 094F 004) a related occurrence located 2.75 kilometres to the south.

The Fram North occurrence is in a region known as the Muskwa anticlinorium, a major north-northwest–trending structure characterized by large, folded thrust sheets that expose rocks as old as Middle Proterozoic (Helikian), as well as Paleozoic rocks (Geological Survey of Canada Map 1343A; Geological Society of America, Geology of North America, Volume G-2, page 639). All belong to Ancestral North America (Geological Survey of Canada Map 1713A). The Middle Proterozoic rocks are pre-Windermere Supergroup and are known as the Muskwa Assemblage (Geological Society of America, Geology of North America, Volume G-2, page 111).

This assemblage of carbonate and clastic rocks has been divided into seven formations. The Fram North showing is in the Aida Formation, a 1200- to 1800-metre-thick succession of dolomitic mudstone and siltstone; dolostone and minor mudstone, sandstone and limestone (Geological Survey of Canada Memoir 373, Paper 67-68). In this area, as well as regionally, these rocks are unconformably overlain by Lower Cambrian sedimentary rocks of the Atan Group. All rocks are gently folded, and some have slaty cleavage. The Proterozoic rocks are cut by northwest- to northeast-striking, steeply west-dipping diabase and gabbro dikes; they are truncated by the Lower Cambrian unconformity (Geological Survey of Canada Memoir 373). Contact metamorphism affects the country rocks for up to 1 metre away from the dyke contacts, shown by chlorite, actinolite and epidote. The dike contacts are commonly sheared.

At the Fram North showing, the Aida Formation strikes northwest and dips 30 degrees southwest (Assessment Report 2875). The rocks are intruded by a diabase dike that has sheared margins. A quartz-carbonate vein in this north-northeast–striking, moderately west-dipping shear zone contains galena and minor copper (mineral not specified, but probably bornite or chalcopyrite), and probably pyrite. A chip sample taken over 50 centimetres assayed 3.21 per cent lead, 0.33 per cent copper and 51 grams per tonne silver (Assessment Report 2875, Map 1).

Work History

In 1970, Windermere Exploration Ltd. completed a program of geological mapping and rock sampling on the area as the Fram claims.
