Ann: HCH Commence Next Phase of Expansion Drilling at Costa Fuego, page-40

Playing around with some of the data in the announcement.

The photo is probably taken from near the pad of 2023 hole #223. Probably the hole being drilled in the photo because the azimuth implies something like that.


Not easy to distinguish drill pads in the valley but the roads/access up the far side does help for holes on the far slope - may not be totally accurate.

Transposing the plans for Jan 2024 onto google earth - Cortadera only. Maybe more later.



5 holes planned testing priority targets. Hole locations are approximate with large white spheres/circles

Fine tuning of these priority targets has occurred since 2023 with the one being deep tested by Hole 3 added. Mimdas chargeability anomalies are one reason for the changes - when was that work done??

Holes 1 and 2 are testing deep chargeability anomalies (suggests presence of sulphides but Pyrite or copper sulphides or... need the drill bit; other possibilities though less likely in this geological environment.)
Holes 223 and 224 had assays pending at the last quarterly but no comment in this recent announcement suggests low to barren..
Hole 1 is planned at almost the opposite azimuth to hole 223.
Carola hole F19 was 1153m to the NW with NSR reported using a Cu 0.4% cut off (perhaps - no definitive data found). F19 tested areas that hole 1 will go to at depth. Core storage means geology data are/were probably available to be rechecked.
Flat lying cover sequence means hole 1 may not have much of interest to test in the first 1-200m.

Hole 2 is possibly going to be an extension of 224 (perhaps not as dip seems steeper in sectional view). The "IP" anomaly is maybe halfway down the planned hole though there are projection issues not easily resolved with the figures.

The majority of holes on the south side of the purple priority target with holes 1 & 2 are drill away from it.
Detail of area for holes (arbitrarily) numbered 1 and 2.




=================
Hole 3 a deep test of an "IP" anomaly S of Cuerpo 1; SW of C2.




Hole 4 is in a medium priority area where several pads have been established in the last couple of years but not drilled. The easterly azimuth is possibly at right angles to late intrusives

Hole 5 has possibly been tested peripherally by Carola hole F39 (Drilled N 000 degrees to 743.5m NSR as for F19 above for assays). The lines on section B-B' indicate the plunge suggested by C1-3 mineralisation - perhaps.

========================
The targets have not been well tested or not tested before so brown to near green fields exploration even though close to known mineralisation. Even one out of the four targets giving good results will be a win. More better.
