The Hebrew occurrence is located on the western side of Neekas Cove on the Don Peninsula, approximately 26.5 kilometres southeast of the community of Klemtu.

Regionally, the area is underlain by high grade metamorphic rocks and orthogneisses which have been intruded by quartz diorites.

Locally, the occurrence is associated with a band of epidote-garnet skarn which averages one to three metres in width, in a belt of intercalated marble, greenstone, and biotite-hornblende schist. These rocks are of probable Triassic age and may represent a pendant or inclusion in the granodiorite batholithic rocks. Mineralization consists of lenticular masses of pyrrhotite and pyrite with some sphalerite and a little chalcopyrite occurring along lines of schistosity and also along planes of jointing.

The property was Crown Granted to McKay and M. Moss in 1882. In 1931 W.A. Robbins drove a 6.7 metre adit from the west bank at the mouth of the Neekas River. The adit appears to follow bedding planes within the intercalated greenstone and marble. Bedding strikes approximately 310 degrees and dips near vertically.

In 1952 the area surrounding the Hebrew Crown Grant was staked as the Neekas 1 to 12 claims (see Neekas, 103A 004). Workings on the Neekas consisted of a series of open cuts which exposed the mineralized zones about 1200 metres to the northwest and 250 metres to the southwest of the adit. Kennco Explorations Canada Limited and American Smelting and Refining examined the property in 1953.

In 1987 the area was staked as the Neekas claim by Lac Minerals, who conducted an exploration program of soil and stream sediment sampling and geological mapping. A 2.5 metre chip across the adit mouth on the old Hebrew Crown grant assayed 2.12 per cent zinc and 0.15 per cent copper (Assessment Report 16148). In 1991, Cascadia Prospecting Syndicate staked the area including the Hebrew and Neekas showings and conducted rock, silt and soil sampling, hoping to find evidence of volcanogenic massive sulphide mineralization. The work confirmed that the showings are skarns. The best grab sample returned a value of 10.72 per cent zinc (Assessment Report 22139).
