Very encouraging news from Esa4 May 2023 09:12
For those not up to speed, Esa is a 20.6 square kilometre block, made up of 86 individual claims.
It lies just 10km from Barrick's Hemlo mine, to the north east. That mine is a 23m oz resource. Ouch.
Here's the background: When they took the block, known geology suggested a possible east-west sheer through the middle of the block, with a possible sub-parallel one to the south within the area too. The little historical work that had been done suggested a similar mineralisation to that at Hemlo
Last year two things happened: 1. A previous claim holder supplied First Class with their raw VTEM data free of charge. That saved FCM about £100k. 2. They did a soil sampling campaign, collecting 150 samples at the inferred shear.
All of this has been sent to a specialist firm (Paterson Grant and Watson) to interpret. They interpreted the VTEM data in November last year, and as a result the ground team grabbed some extra soils in the last few weeks before everything froze solid, staying in the area long after most exploration field teams have packed up for the winter.
What's now happened is that the soil samples are back, mapped against the previous geophysics and it looks like PGW may further have corroborated how the soils fit onto things. They found a 4km zone that corresponds to the suspected sheer (not known to be in an arc shape - I love the world arcuate). Multiple samples contained gold in the range 10-95 ppb which is considered good for systematic soil sampling for gold. They also found Molybednum, ****nic and Antimony - which are metals that often occur near gold deposits and so suggest you're on the right path for the gold.
Two other things: 1. There are a couple of other structures showing on the VTEM - one aligned N-S, the other N-NE. The highest figures appear to be where these intersect the sheer. 2. They found a boulder that resembles the rocks found at the Barrick Hemlo mine with 0.7ppm gold in - very good for a grab sample.
Remember: This is all being investigated because of the proximity to Hemlo, and the similar geophyics and geology.
These results would be astounding anywhere someone was looking for gold, and would warrant further ground work and eventually drilling. But the thing here is that it backs up the theory that something very similar is going on at Esa to what caused the deposit at the Hemlo mine. That's a very exciting theory to be firming up. They could be onto something big.
