Point Location Description: Pits, small adit, diamond drill holes.
Location Method: Conversion from MDI
Access Description: The main showing straddles the Trans Canada Highway 17 approximately 1.6 km west of Schreiber in Priske Township (claim map G 631, Priske Township). Most of the pits and the old adit are within walking distance (approximately 75 m) south of the Trans Canada Highway. The three diamond drill holes are collared about 50 m north of the Highway over a distance of 243.8 m. The CPR main line crosses the southern margin of the old Elwood claim group.
1935: Claim TB 9627 was staked by J.D. McCashen, and a patent granted. 1937: Claim TB 24345 was staked by J.D. McCashen. 1937-1938: Several pits and a short adit were excavated. 1940: The claims lapsed. 1946: L.E. James staked TB 33181. 1948: The claim lapsed and was restaked as TB 37634 by R. McCombe. All interest was transferred to Iron Lake Exploration Limited. A dip needle survey was carried out by Noranda Mines. 1950: The claim lapsed. 1951: TB 9627 came open for staking. TB 37634 was restaked by L.E. James as TB 41507. 1953-1955: Unspecified work was carried out by James. 1956: An airborne geophysical (EM) survey was conducted by Geophysics of Canada Limited. 1957: The claim lapsed and was restaked as TB 86768 by J.C. Guindon. A contiguous claim TB 87269 was staked by G. Allaire. Elwood Mining Exploration Company Limited acquired the two aforementioned claims plus nine contiguous claims numbered TB 86760 to 86767 inclusive and 86769. A follow up ground geohysical (EM) survey was carried out by McPhar Geophysics for Canabel Syndicate (sponsoring Elwood) and delineated 4 major zones. A geological survey was conducted by C. Authier. A report was submitted by L. Germain. 1957-1958: Three diamond drill holes totalling 301.8 m were drilled on (main) Zone 'C' (TB 86768, 87269) but the results were not encouraging. 1959: All interest was transferred to Amalgamated Mining Development Corporation Limited. 1962: The claims lapsed. 1981: TB 86768 was restaked by A. Wilson as TB 604172. J.E. Bond II and D.N. Mochnick each received 33.3% interest. 1983: The remaining one third interest was transferred to New Ambrose Resources Inc. (United Continental Energy Corp., Livingstone Energy Corp.). A combined airborne geophysical (magnetic, EM, VLF EM) survey was conducted by Aerodat Limited. Claim TB 87269 was restaked by M. Peplinski as TB 727285 (previously TB 9627). 1985: Geological mapping and sampling was carried out by Lincoln Resources Inc.

Dec 07, 2005 (B Nelson) - Massive sulphide stratiform base metal mineralization occurs in sulphide iron formation hosted by metavolcanic rocks. According to Carter (1981a) the Morley and Elwood showings represent faulted offsets of a single iron formation, occurring at the interface of two volcanic cycles. (Resident Geologist's Files, Schreiber Hemlo District, Thunder Bay) *Germain (1958) noted that: A number of mineralized zones were observed in the course of the geological survey. In every case, the mineralization consists of pyrite and pyrrhotite with subordinate amounts of marcasite. The strongest zone runs across claims TB 86768 and 87269 and has been traced for a distance of about 1,200 feet. Diamond drilling also established its continuity in depth. The zone consists of massive pyrite and pyrrhotite across a width of about 7 feet and is found within a band of lean iron formation. Gow (1985) describes the Elwood occurrence as a chemical sediment/iron formation/clastic sediment package. Five major units were recognised across the property from south to north including basic volcanics, chemical sediments, intermediate to felsic volcanics, chemical sediments and more basic volcanic rocks. Massive sulphide layers (normally pyrrhotite) up to 8 feet thick are intercalated within the chemical and clastic metasedimentary rocks. On the eastern side of the property a conglomeratic rock typically with pumicious fragments in a matrix of fine green magnetic rock was discovered, and resembles a silicate facies iron formation.

Dec 07, 2005 (B Nelson) - *Germain (1958) stated: No base metal occurrence of possible economic interest was observed anywhere on the property and, none was encountered in the 257.2 m of diamond drilling conducted. *Germain (1958) noted: A representative sample of the mineralization yielded traces of zinc by spectrographic examination and, 0.24 oz. silver and 0.06% copper by assaying. Three diamond drill holes put down across the zone failed to yield better values in base metals and silver. Seven samples collected by Gow (1985) of massive sulphides and conglomerate assayed up to 10 ppb Au, 110 ppm Zn and 171 ppm Cu. Assay results were discouraging. Zinc mineralization is reported to have been intersected while drilling a water well hole on the north side of Hwy. 17 and on the southeast end of Walker Lake (Walter Acker, Prospector, personal communication, 1989). (Resident Geologist's Files, Schreiber Hemlo District, Thunder Bay).
Jun 29, 2018 (Therese Pettigrew) - A number of mineralized zones were observed, consisting of pyrite and pyrrhotite with subordinate amounts of marcasite. The strongest zones has been traced for a distance of about 365.76 m and consists of massive pyrite and pyrrhotite across a width of about 2.1 m and is found within a band of iron formation (Schnieders et al., 1996).
