GOLD PROSPECTING

HUMAN v. ELECTRIC TORONTO. March 23. The old-time gold prospector will go on. Electrical instruments may help in locating ore bodies for swifter development, but they will not replace the professional gold-hunter who leads the way into new mining country. Hans Lundberg, Toronto geologist and a proponent of the electrical system of uncovering ore bodies in Canadian properties, says that high cost [would prevent extensive exploration by men equipped with the apparatus. “After new discoveries have been made by prospectors, geologists trained to make competent deductions from the use of electrical and other scientific instruments can advise companies where they may most profitably drill for ore. hut the finding of new areas must be left, to the old-time prospectors because it is so much cheaper,” he said. Mr. Lundberg said the electrical method consisted of finding the conductivity of the ground. The Ontario Government last week passed an ordor-in-council permitting use of electrical methods by a company in locating underground deposits in northern Ontario.

“Quartz lias the least conductivity and where it is found in the right formation there is a presumption of gold." ho said. "Sometimes gold is found in sulphides with other minerals and these give the greatest conductivity, Findings are always checked by the electro-magnetic and other methods before definite coiiclurions are reached, The •electrical method is useful in locating oilier minerals than gold, declared Mr. Lundberg, who said a parly now is in Newfoundland tracing a lead and zinc formation, another in northwestern Ontario checking a

chromium. These are in addition to seven parties using the method to check on gold deposits in Quebec and Northern Ontario.
