The Columario mine is located 11 kilometers east of Terrace.

Andesites of the Jurassic Hazelton Group are intruded by diorite and granodiorite stocks of the Cretaceous to Tertiary Coast Plutonic Complex. These rocks are cut by quartz albite, diorite and lampro- phyre dykes.

Seven fracture related, parallel quartz veins, mineralized with pyrite, arsenopyrite and minor chalcopyrite and galena, occur mainly in the andesite over an area 1300 by 500 metres. The veins strike 155 degrees and dip 30 to 60 degrees northeast. They average one metre in width and are up to 700 metres long. Gold is associated with the pyrite and a 90 kilogram test sample assayed 49.4 grams per tonne gold, 120.3 grams per tonne silver, 0.42 per cent copper and 0.02 per cent lead (Geological Survey of Canada Memoir 329). The veins were discovered in 1919, and by 1934 Columario Consolidated Gold Mines, Ltd. explored the seven vein systems with 11 adits and about 2,400 metres of underground development. In 1934, a 91 tonne per day mill was constructed. Actual tonnage mined is not known, but production of precious metals recorded in 1934 and 1935 was 21,150 grams of gold and 58,101 grams of silver.

In 1987 Endurance Minerals and Hillsborough Resources through joint venture spent $374,000 on the property.

CONCLUSIONS

The detailed mapping has established the rock sequence hosting the mineralized veins and the subsequent intrusions that have displaced the veins. It has also established three major fault generations with other minor ones that have greatly affected the continuity of these veins. Additional information can be obtained by continuing this type of work on the 4 adit and especially on the 1 adit. It is almost certain that these three veins, which appear to be of limited extent on the old maps, are indeed continuous and cut across the whole sequence of diorite-andesite both further to the south as well as up and down dip to the 1 adit and below. They are expected to terminate however, at the contact with the younger granodiorite to the west and further to the north of the underground openings.

Gold mineralization in the granodiorite itself could also be present not necessarily as quartz veins but in another form, such as of the porphyry type. Surface exploration should take into account host rock lithology and related styles of mineralization, i.e. quartz veins in mafic intrusives and porphyry type in felsic intrusives.

The assays received so far indicate erratic distribution of gold along the 4 and 5 veins. The arithmetic average of all samples from the No. 4 vein - if the high assays are not cut - would be low, probably just less than 0.1 oz/ton. This, however, would not be indicative of the true average. This is caused by the presently limited exposure of the vein (result of previous mining of high grade pockets) and limited exposure in the rest of the mine. Well-mineralized shoots along this vein across good widths (greater than 0.5 m) are not uncommon. Frequent occurrences of such shoots, which are believed to be present along this vein, would drastically change the average grade. From the present exposures it would also appear that the No. 6 vein, which shares many features with the No. 4 vein (width, mineralogy, alteration), has consequently, a similar economic potential.
