I want to say something in answer to the same argument because I think it must be dealt with now. First of all may I say, in the somewhat more robust language of the north, that the hon. member for Timiskaming made a damn fine speech this afternoon. McIntyre mine has been referred to. I have been underground in McIntyre many times. Some years ago McIntyre discovered what is known as the twenty-five vein system. It is to the north of the property. It is a nearly vertical vein structure of quite high grade. It runs about an ounce per ton which is about four times the average grade at the mine.
As the hon. member for Timiskaming said, the ideal is to have a mill feed of constant grade running to the mill. The situation at McIntyre is that in the old Pearl lake porphyry area and the other older parts of the mine the grade may run from -15 to [DOT]2, perhaps even less than -15. This ore is mixed with a proportion from the twenty-five vein system area to bring the average grade up to what the minister said, about -29 ounces per ton.
So far as increased costs are concerned, let me take the case of Kerr-Addison. At the present time Kerr-Addison is probably the greatest gold mine in Canada and North America. Quite conceivably it may become the greatest gold mine in the world. It has a wonderful deposit of ore. Years ago before the war they cut off mining or hoisting or breaking ore when they got below -06 ounces per ton. As costs rose they stopped breaking at -07 and as they rose further at [DOT]08, -09 until now I believe any rock containing less than one-tenth of an ounce is considered waste rock.
The quantity of ore between -06 ounces per ton and -1 ounces per ton runs to many hundreds of thousands of tons, and many thousands of dollars' worth of gold is lost to Canada and to the national wealth of the country for all time. That is an example of what increased costs are doing so far as the destruction of our national wealth is concerned.
With regard to the question of sealing off, in one, maybe two, and possibly three cases that I know of an extremely high grade section was discovered and sealed oft. I think the highest grade section was discovered some years ago at the O'Brien mine in the Cadillac area. I have forgotten what it ran, but it was 20, 30 or perhaps even 50 ounces per ton over a very short distance and a very small ore chute. I am not sure how big it was but I saw the ore in place and it was just like looking at the national mint. It was a very beautiful sight. But it was a very small occurrence and to safeguard that very high grade deposit the stope was barred and locked to prevent high grading. That was some years ago.
There may have been one or two other cases. Siscoe had some high grade and there may have been other cases where, a small chute of tremendously high grade ore having been discovered, it was wired off for a temporary period simply and solely to prevent high grading until such time as the ore could be mined. Incidentally, that was a long time before the Emergency Gold Mining Assistance Act came into force and had nothing to do with sealing off high grade ore in order to mine low grade ore. What the hon. member for Timiskaming has said is absolutely correct. It is nothing short of ridiculous to think that any mine would seal off high grade today.
