Access Description: The occurrence is located in Priske Township about 2.4 km south southeast of Schreiber (Mining Locations R606, R609, claim map G 631, Priske Township). Access may be gained via the old Schreiber dump road (Worthington Bay) which branches off Highway 17, 4.4 km east of Schreiber. The road extends approximately 3 km south and west to a small clearing where the Morley Road occurrence is found. The High Grade occurrence is located about 400 m west of this clearing, near the top of a high hill.
Pre-1897: Mining location R606 and R609 were owned by Morley however little work done. 1897: The location was sold to Davis Sulphur Ore Company who exploited a pyrite pyrrhotite ironstone unit near the high grade occurrence. 1932: The property was offered for sale or option. 1936: The high grade vein was prospected by Prospectors Airway Limited (PAL) Exploration Co., and the vein was stripped over a length of 68.6 m. 1955-56: Geological mapping and systematic sampling were conducted by Thorncrest Explorations. Drilling was conducted under the Morley Road occurrence. 1960: Temanda Mines Ltd. conducted a geological compilation, and drilled 5 holes on the high-grade vein totalling 845 feet. 1963: Denison Mines Limited carried out sampling and assaying. Three diamond drill holes were drilled of unknown length. 1983: The Morley Pyrite claims (R606, R608, R609, R610, R660, R665), formerly owned by T.C. Armstrong, were optioned to J.E. Bond II and D. Mocnik. Trenching and sampling carried out by New Ambrose Resources Inc., Bond and Mocnik following airborne geophysical (VLF EM, magnetometer, EM) survey. 1986: Lincoln Resources Inc. conducted a reinterpretation of airborne geophysical data, ground geophysical surveys, line cutting, geochemical surveys, geological mapping, trenching, prospecting, sampling, and drilled 4 DDH totalling 500 m. 1989: D. E. Christianson conducted prospecting and sampling with a JK Smith sampling drill with the help of an OPAP grant. 1994: D.E. Christianson conducted a VLF-EM geophysical survey, mapping, prospecting and sampling.

Dec 07, 2005 (B Nelson) - Gow (1985) describes the Morley property in general as containing chemical and clastic metasedimentary rocks which locally include bands and pods of sulphides (Morley Pyrite, Morley Road), which separate basic metavolcanics in the northwest from felsic metavolcanics in the south. The metavolcanic rocks have been intruded by a number of different intrusions including quartz feldspar porphyry, granitic rocks and dioritic intrusions. Later discordant diabase dikes also cut the metavolcanic rocks. The Morley High Grade Vein appears to represent a discordant vein structure. According to Patterson et al. (1984 p.93): The Morley High Grade occurrence could be classified as either a Terrace Bay Batholith Contact Zone Type (1) or a Lead Zinc Silver Vein Metavolcanic Type (2a). However, due to the concentration of gold mineralization and its relationship to felsic metavolcanics, it is described under this mineralization type. (Metavolcanic Hosted Dilatant Zone Type). A narrow calcite vein strikes 5 degrees to 10 degreesN and dips 55 degrees to 70 degreesW. The vein varies in width from 10 to 30 cm and is exposed for over 70 m. The vein is hosted by sheared, silicified and carbonatized felsic metavolcanics with a fragmental texture. The vein contains bands of massive sp and gn, with minor py and cp, and displays a brecciated texture. The vein is cut off by a diabase dyke to the south and pinches out to the north. The vein has reportedly been traced for over 1500 feet by trenching. The Morley vein may represent the northern extension of the Longworth Silver vein, or a similar parallel vein.

Dec 07, 2005 (B Nelson) - Harcourt and Bartley (1939) described the Morley High Grade occurrence as: a fracture strikes N10 degreesE across an altered rhyolite agglomerate. The fracture, which has been stripped for 225 feet, is occupied by a vein composed of calcite, bands of massive sphalerite, galena, and chalcopyrite. The vein has a maximum width of one foot and pinches out at each end. Harcourt (1939, p.26) notes that a grab sample of the vein material assayed 5 ounces per ton Ag and 0.53 ounce per ton Ag and 0.53 ounce per ton Au. Thirty samples collected by Thorncrest Explorations Ltd. in 1956 averaged 0.196 ounce per ton Au, 41.57 ounces per ton Ag, 25.85% Zn, 7.06% Pb and 0.185% Cu. Average gold: 0.118 ounce per ton Au and 19.26 ounces per ton Ag (Resident Geologist's Files, Schreiber Hemlo District, Thunder Bay). The Erie Canadian (Sylvanite) sampling shows values from 0.4 to 0.25 ounce per ton Au and 14.38 to 65.66 ounces per ton Ag across widths from 0.33 to 1.39 feet (McLeod 1983). Diamond drilling in 1963 intersected low gold values up to 0.07 ounce per ton Au, and up to 12.16 ounces per ton Ag in sludge samples. Gow (1985) described D.D. No. 1 of Thorncrest Exploration Limited as being 392 feet under the Morley Road Showing. Given the dip of the Morley High Grade vein, this hole may have intersected the Morley High Grade vein. The hole is reported to have intersected brecciated quartz and porphyry from 8 to 157 feet, but apparently lost almost the entire core between 157 and the end of the hole at 392 feet. The only core recovered included 4 inches at 214 feet which assayed 0.08% copper, 16.69% zinc and 2.07% lead, 2 inches of core at 334 feet which was not assayed but which contained galena and chalcopyrite and a final 17 feet of the hole (375 to 392 feet) which is reported to have been well mineralized, to have contained copper, lead and zinc but which was not assayed.
