There is a good reason this area of Ontario has never been fully explored for minerals as it is not easy to access, remote and severe winters. However the Ontario Government is evaluating access and a Diamond mine is in production not that far away. Gas, Food and amenities we take for granted are all very expensive so mineralization has to be sizeable and rich.
This is an enormous sized area to explore with a huge number of prime targets identified by aerial and ground followup surveys. No one find or deposit has to carry all the infrastructure cost as over time multiple deposits of various quality/quantity will be identified. The grades being identified are almost off the chart and perhaps the best found in past 10 years. These are early days indeed and yes it's speculative but potential payoff over months and years could be huge. Not often one comes across an area play that potential can be a 10 or 20 bagger.
