Mineralization Comments

Jan 16, 2007 (Mark Puumala) - Parker et al. (1995) report that mineralization at the Hydroline Occurrence consists of pyrite and magnetite with chert in rock described as chlorite muscovite schist. Ackert (1997) further reports that mineralization is associated with discontinuous quartz veins and irregular masses in sheared (101/90) chlorite muscovite schist. The shear zone is reported to be folded, with the fold hinge plunging 30 degrees to the west. This occurrence is located in close proximity to the contact between the chloritic schist and trondjhemitic intrusive rocks related to the North Bamaji Lake Intrusion (Ackert 1997). Assays of up to 0.067 oz/ton Au and 0.236 oz/ton Ag were reported by Parker et al. (1995) from this zone. Mapping by Wallace (1985) also indicates the presence of a radioactive anomaly in the vicinity of this occurrence.
