Point Location Description: Mine shaft cap

Location Method: Data Compilation

Access Description: The property is located in northeast Rickaby Township, approximately 38.6 km northwest of Geraldton, and approximately 200 m north of Atigogama Lake. The property is accessible by travelling 8 km east of Jellico on Trans-Canada Highway 11, and following Camp 40 Road northwest for 19.2 km to the Ministry of Natural Resources Atigogama Lake access point. Proceed on foot to the first ridge north of the Camp 40 road.

Exploration History

1933: The property was staked by T.A. Johnson who subsequently discovered gold. 1933-34: Dikdik Exploration Co. mined ore from an open cut 20.4 m long and 15.2 m deep. A shaft was sunk from the bottom of the open cut to a depth of 48.8 m with the first level established at 45.7 m. 1934-35: Development continued, in the form of shaft deepening, drifting and cross-cutting. Three small stopes were mined. 1935: A 20 ton per day mill was installed. 1935-36: Orphan Gold Mining Corp. acquired the claim, but no dev't or prod'n took place. 1937: Workings dewatered by Sarmac Gold Mining Operations Ltd., but operations were suspended before any further work could be done. 1940: The mine was acquired and held by B. Craibbe. 1965: the claim was transferred to H.K. Craibbe. 1981: The claim was transferred to Canadian Gold resources inc. and later to Northway Resources Inc. 1982: Northway Resources was taken over by Rockwell Mining Corp. 1984: Rockwell merged with seven other companies to form Kidd Resources. 1985: Dikdik Mine held by Kidd Resources, who carried out EM and magnetometer geophysical surveys. 1986: Canadian Gold Resources optioned the property and conducted line cutting and ground geophysics. 1997: the Koch-Daneff zone and the New Vein were stripped and sampled. 2008: Highland Resources Inc. conducted trenching. 2008: Canadian Prospector Inc. conducted stripping and trenching. 2009: Highland Resources conducted mapping and sampling.

Geology Comments

Dec 07, 2005 (B Nelson) - A large part of the claim block covering the Dikdik Mine is heavily drift covered. Scattered outcrops show that much of the consolidated rock on them is granite. Apparently lavas occur only on the southeastern claims. Tongues of granite extend southwestward from the main mass into the greenstone. The contact between granite and andesite is remarkably sharp. In the nine working the granite tongue seems to plunge southward at a high angle. Clearly, the fracturing occurred after the granite had solidified sufficiently to be sheared. Quartz lenses occurin a shear zone crossing the contact between the granite and andesite. The ore bodies are parts of irregular lenses of quartz which in places bulge to widths of 2.5 m. A width of nearly 3 m is recorded in one place. From the contact in both directions the vein becomes narrower and finally seems to feather out. The gold content of the narrow lens that was removed in the open cut was exceptionally high. In general the values are higher and more consistent where the wall rock is lava. There are, however, lenses of good grade in the granite, but the gold seems to be much more eratically distributed in them than it is in lenses within the lavas. Apparently the content diminishes rather rapidly as the lenses are followed into the granite. Fritzshe states that the widest as well as the richest parts of the ore lenses occur where narrow fissures now filled with calcite intersect the quartz-filled fissure.

Lithology

Lithology Comments

Dec 07, 2005 (B Nelson) - Lava forming the walls of the vein was apparently not much affected by the vein-forming solutions. Granite wallrocks show considerable alteration. Lava from the wall of the vein is dark-green in color, massive and fine-grained. Pyrite occurs commonly as disseminated grains. Chlorite and epidote make up most of the rock.

Mar 29, 2016 (Therese Pettigrew) - The Dikdik Mine area is underlain by the Kaby Lake Stock which intrudes a felsic to intermediate metavolcanic unit, a portion of the Tashota-Onaman Belt. The Kaby Lake Stock is a "massive to light grey granodiorite to trondhjemite with local occurrences of granite and quartz monzonite". Metavolcanics at the mine have been described by Mackasey and Wallace (1978) as crystal tuff and laminated tuff but as andesites by Bruce (1936).

Mineralization

Mineralization Comments

Dec 07, 2005 (B Nelson) - The quartz of the vein is white and so fine-grained that it is almost chalcedonic. In parts of the lenses metallic minerals make up a considerable part of the vein filling. The most abundant of these is pyrite. Gold in visible amounts occurs sparingly. It is very pale in color on account of a large mixture of silver. The gold usually occurs in pyrite and is commonly associated with galena. Samples taken from the waste dump in 1981 returned values of 3.62 oz/ton Au and 2.58 oz/ton Ag; 5.78 oz/ton Au and 2.94 oz/ton Ag.

Alteration Comments

Dec 07, 2005 (B Nelson) - Granite near the vein is a grey granular rock with abundant quartz. Under the microscope it is found to be thoroughly altered. It contains quartz, sericite, calcite, pyrite and chlorite. Feldspars have been changed to a mat of sericite. Some quartz occurs as mosaics, probably formed by the breaking down of silicates. Biotite is the most distinctive of the alteration mineals.
