I haven’t looked at the data, but junior mining and exploration is a bit of the wild west in terms of honesty and would not in the least be surprised if some trickery is at play to produce that result. Also a reason why it’s not advisable for new investors to get into this sector.

If you're going to put money on a mining exploration result you want to put it on JORC (or equivalent) certified results from a filed Technical Report at the Toronto TSX (or London Metals, Sydney Mining, South African Exchange, etc)

JORC is Australian standard, however Anglo-Australian mining transnationals with the TSX as home base are the biggest mining concerns on the planet ATM.

Here is a third party discussion of the JORC definitions of 'Resource' Vs 'Reserve'

* Mineral Resources can be classified as Measured, Indicated and Inferred, according to the level of geological knowledge and confidence.

* Ore Reserves can be classified as Proved or Probable on the basis of the Mineral Resource classification and consideration of all JORC modifying factors.

'Resources' can be wishful thinking until they're actually Measured (to a degree of confidence).

In their report on page 7, they say they drilled to 2200m: https://norgemining.com/wp-content/uploads/2021/11/Norge-Min...
