Mining is the largest part of our economy. The north was built on mining, primarily gold mining. Now 40% of our economy is based on mining, and it's all diamonds. We have four diamond mines. We export over two billion dollars' worth of diamonds annually.
For oil and gas, with the downturn in oil prices, every oil and gas producer in the Northwest Territories has pulled out of the north, so we have no activity other than in Norman Wells, which has been there since 1939, before the war. We're very concerned, and as I said earlier, we have tremendous oil and gas potential. We have over seven billion barrels of oil and about 100 trillion cubic feet of natural gas that's still all underground. Certainly the fact that there's nothing going on in exploration is a cause for concern.
