The reason everybody thinks that way, and about Kenora, is a function of when the mining ended there and what the technology was at the time. Recovery in the Primitive Kenora and dryden mines was often less than 25%. In the southwest states where cyanide and halogen leaching was first developed, roasting and subsequent processing by cyanide had raised recoveries to 80 -90 % despite very refractory ores. By the mid 1930's the banning of roasting fumes and the fixed gold price sounded the knell of mining of the SW ores. And the Western Ontario stuff, which suffered many travails and the weakness of the state of capital markets of the time, died an unnatural death. Ontario's greatest producing mine of 1890 had ended with a whimper by 1945 despite robust half hounce grade. The richer, larger regime of volcanic ores, hyperthermal in nature and not quite duplicated anywhere else save the Motherlode area of California, won out with their continuity down plunge. These wonders of geology came into their own with the then fabulously rich ores of Kirkland Lake with the mightly Lakeshore leading the way and confounding the geologists of the day who espoused basement structure cutoffs from weary tomes. Perhaps the QV ores of NS, meagre though they may seem, have just not seen a revisit with modern technology and reevaluation with the post 600 gold prices. EC<:-}
