Noront had such grades and much much better, and similar grades over longer lengths  with their Windfall property but the property was very nuggety and the property has required ~750,000metres of drilling or thereabouts from what I recall. Generally , one prefers to see multiple intercepts 100+gram-metres,. In this case the interval is merely 27gram-metres...
