All samples were collected far away from the gold lodes, and are thus largely unaltered.
But, of course, it is a question of lode mining: it is speculative and hazardous.
First, tin comes in the form of lodes rather than in veins.
The lodes are extremely narrow and very spasmodic.
There are possibilities of a few metal lodes, but probably a more fruitful source of deposits for mining will be horizontal layer deposits.
And the vein of tin or lode may be very small, perhaps no more than the thickness of a man's thumb.
The tin comes in lodes and not in veins, which means that several test drillings are required.
In other words, the tin is extremely spasmodic, it is non-persistent, it is found scattered over a wide area, and in extremely narrow lodes.
