Oct 11, 2006 (Mark Puumala) - The geology of the Miminiska Peninsula area was mapped by Wallace (1981), who identified three major supracrustal rock sequences. These include two mafic metavolcanic-dominated sequences and one metasedimentary rock-dominated sequence. The oldest of these units is interpreted to be a thick, predominantly mafic metavolcanic sequence that is found in the southern portion of the Miminiska Peninsula and the area immediately south of Miminiska Lake. These mafic metavolcanic rocks have in turn been interpreted to be overlain by a metasedimentary rock sequence that is dominated by wacke and mudstone, but also contains significant thicknesses of banded iron formation. The metasedimentary sequence is overlain to the north by a second mafic-metavolcanic rock-dominated sequence. A significant unit of felsic to intermediate pyroclastic rocks has also been mapped in the western portion of this area (southeast of Howells Lake). This unit is located immediately south of the metasedimentary sequence west of Miminiska Lake, but is enclosed within the metasedimentary rocks further to the east. This area is bounded to the northwest by felsic intrusive rocks of the Troutfly Lake Batholith. Stratigraphic units in the vicinity of Howells Lake generally strike approximately northeast, with steep, near-vertical dip. Further to the northeast, towards Keezhik Creek, stratigraphy strikes in a more easterly orientation. Wallace (1981) indicates that foliation is generally oriented sub-parallel to the primary sedimentary bedding and igneous flow contact features. Foliation and shearing are noted by Clark (2005) to be most prominent in tuffaceous mafic metavolcanic layers. Wallace (1981b) mapped a number of northeast-trending faults and lineaments in this area. More recent maps (e.g., McKay 2004) illustrate a northeast-striking fault that parallels the metavolcanic/metasedimentary rock contact in the vicinity of Howells Lake. This structure appears to be related to many of the gold and antimony/gold occurrences in this area.

Oct 11, 2006 (Mark Puumala) - The Howells Lake prospect is located in close proximity to a contact between metasedimentary and metavolcanic rock units that has been interpreted as a fault (northeast-striking) on a geological compilation map prepared by McKay (2004). The occurrence of possible economic mineralization in this area was first reported by Prest (1939), who noted the presence of pyrite-mineralized porphyry intrusions and massive stibnite float on a small island in the northeastern portion of Howell's Lake. An unpublished property visit report prepared by John Scott in 1977 that is available in the Thunder Bay North Resident Geologist's Office Mineral Deposit Files indicates that economic mineralization at this location consists primarily of stibnite and gold, with minor galena, sphalerite, silver and tetrahedrite. Mineralization occurs primarily in quartz veins, with some also present in the host rocks. The quartz veins are described as being approximately perpendicular to an unconformity between the volcanic and sedimentary rocks. The presence of an unconformity at this location had been interpreted by New Jersey Zinc (holder of the claim group at the time). This contact may be equivalent to the fault interpreted by McKay (2004). Patterson et al. (1986) report the presence of an extensive zone of carbonate alteration associated with a nearby quartz porphyry intrusion, and shearing and quartz veining at the contact between mafic metavolcanic rocks and graphitic schist. The quartz veining is indicated to be associated with green mica, pyrite and stibnite. Patterson et al. (1986) also report that Homestake Mineral Development had defined two mineralization zones with the following mineral resource estimates. Western zone: 83,000 tons grading 1.37% Sb and 0.07 oz/ton Au. Eastern zone: 660,000 tons grading 3.1% Sb and with erratic Au grades.
Dec 07, 2005 (C Salo) - Carbonate alteration is associated with porphyry intrusion.
