In BC, get a mining license then stake a mineral claim where you want to go. Hell, why not stake a mining claim right under the land owners surrounding the crown land?!
It gives you the ability to "scout" your claim, regardless of who owns the land your claim is on. Further proof that we don't own anything.
Time to recomend some remedial reading!
Download a copy of the Mining Act for BC. There have been some recent changes (past five years or so) that give land owners a lot more rights than they had in the past, as well as requiring "miners" to actually substantiate that there is bona-fide work being done, plus provide such things as written requests to access (which they must negotiate with the land owner) as well as to have a written work permit signed off by the Mines branch, before work can commence. They are also required to compensate the land owner for damage and losses to crop production, etc. Even then, there is no vested right to access land by crossing private property, to which you do not have a mineral claim.
You also cannot use the claim for purposes other than mining.
We just went through all that to get a "miner" booted off our property in BC. The Claims Inspector was very helpful!
The guy had a pretty nice holiday camp set up, and moss growing on all his "mining" equipment.
In BC, many property boundaries are surveyed out into the watercourses. It depends on when the survey was done, how it was recorded, so "watercourses" as an access route may not be a good one either.
Same goes for Mineral Rights. Many properties are still on record as having the mineral rights included in the Title.
