The showing is defined by a single drill hole ML-1 which returned anomalous values of U3O8.
     The showing is located within a region of Aphebian-aged metasediments of the Mudjatik Domain, as mapped by R.J.C. Munday in 1972 (1977). The metasediments are cut by coarse-grained pegmatites which are anomalously enriched in U, Th and molybdenum.
     Several uranium showings have been located in the area by Scurry Rainbow Oil Ltd, but only one returned high enough uranium assays to warrant a SMDI card. Hole ML-1, which is located within what Scurry-Rainbow Oil Ltd. referred to as the 'E' Zone, is exposed over 220 m (721.8 ft) and consists of a calc-silicate zone which is approximately 15 m (49.2 ft) wide. This horizon is flanked on either side by quartz-biotite schist (unit Q1 meta-arkose) which is cut by pegmatitic invasions. The calc-silicate in this area can be divided into 2 main types:
(1) a pyroxene-rich unit which is medium- to coarse-grained, massive, jade
    to dark green and consisting mostly of diopside +/- hornblende,
    tremolite, feldspar, carbonate, garnet and biotite.
(2) a very hard, siliceous quartz-feldspar unit which grades into a softer, biotite-carbonate-rich calc-silicate.
     Hole ML-1, containing visible orange disseminated secondary uranium minerals, returned the best intersection in the area (1288 ppm U3O8, 1092 ppm U). The uranium mineralization occurs in the calc-silicate zone within the pyroxene-rich unit and at the transition to the more siliceous calc-silicate unit. Isolated blebs of uranium can be seen in or rear fractures in the calc-silicate host.
     R. Munday suggests that the host unit C2 calc-silicate rocks or diopsidites likely represent calcareous metasediments rather than dolomitic metasediments.

     The area of SMDI 1961 was first covered by Dynamic Petroleum Products Ltd. Permit No. 2, staked 3 December 1968. The company flew a geophysical survey and undertook geological reconnaissance of the area in 1969 (AF 74B09-0004). The next year their permit was covered by ground EM surveying, prospecting, geological mapping and soil sampling (AF 74B09-0005) but nothing of interest was found and the property lapsed 1 May 1971.
     The property was staked as CBS 4543 7 October 1975 and owned jointly by Scurry Rainbow Oil. Ltd. and SMDC. Work in 1976 was spread over many of Scurry Rainbow's claims, and consisted of lake water and sediment sampling (AF 74B16-0013), and reconnaissance geological mapping, ground radiometric EM and magnetic surveys, trenching and sampling were done over much of their claim areas (AF 74B16-0023). The following year Scurry Rainbow continued their intensive evaluation of the area. 1:1000 scale mapping was done in the area and pack-sack drilling was underaken, which resulted in SMDI 1961. The lake water and sediment program, and magnetic and radiometric surveys were continued and the company ran a VLF-EM and radon survey (AF 74B09-0012, -0016, and -0024).
     Continued drilling, geological mapping, VLF-EM and radon surveys were undertaken in 1978, accompanied by trenching of interesting areas (AF 74B16-0025). No further exploration of the area was done and the company relinquished its claim 1 March 1986.
