I think a tri-corder is definitely needed. Perhaps a low flying helicopter with an out of window X-Ray flourescence scope. Cominco used them in BC and they worked well. You have to scoot over the showing fairly low and hover for a few seconds or do a slow pass. The handhelds take about 30 seconds to accumulate enough data for an (accurate) reading. Perhaps more powerful sources could collect good relative data in shorter times. You don't need assay quality. Also infrared might work. It works in hand samples. A scanner with a powerful laser or x-rays source illuminator at a height of about 50 feet (most of Labrador is barrens) could get an infrared and/or fluourescence response that could be calibrated. Flourescence takes time to integrate but it is theoretically still feasible as they use it in diamond plants to separate diamonds in a flow. So a slow 20 mph pass over a large outcrop might collect enough data to allow some guesswork to be done. False colour IR work with hyperspectral scanners could be done by aircraft at regular speeds. This is ongoing technology. Also landing and quick hand scanning with standard X-Ray flourescence and IR ID instruments could be done at say 15 minutes for each out crop area of 40,000 sq. feet. ( 20 readings) Hopping 4 men with dual instruments would be efficient. This way in the long light summer you could cover 200 outcrops per day per crew. You go back to the high reading areas for more detailed sampling. I guarantee you in one summer you come up with several hundred copper nickel showings out of say 20,000 readings. Might as well do some dirt bagging and Lake sed sampling with a separate crew since you have the bird there. Nothing like saturation recon. *****************************************
