RE:Hole 505 "The 3rd one of about 40 metres is a bit confusing but it is also in play as a new zone possibly? Maybe someone can help me with that," - Blue Chipper.
Yes.
The 15 December new release (NR) identified three sections in the 505 drill core.
1. Three intersections of underside of the Eastern zone
189 to 194 5 metres
199 to 210 11 metres
275 to 277 2 metres
I
These had visible gold.
2. Intersection of the 463 Zone
393 to 414 21 meters
"intersected three (< 1 m-wide) visible gold (VG) bearing veins" - NR
3. Deepest Intersection of mineralization
480 to 520 40 meters
"The deepest mineralized zone with 1%-5% stringer/disseminated pyrite +/- arsenopyrite associated with massive (1 m) quartz veins and irregular narrow veins and stringers was intersected from 480 m to 520 m. Significant quartz veining (10%-30%) noted in other parts of the hole will also be assayed," - NR
Tim Froude talks about this deeper intersection of mineralization at
18:45 in an interview on "Rocks and Stocks" included within a 150 meter zone of veining.

Starting at 18:45 he says, "The hole pretty much ended in veining all the way down to 559 meters." "We drilled through almost ... 150 meter of variable veining...."
Speculation (Is There a deeper VMS deposit?) We have:
- 150 meters of variable veining containing 40 meters of mineralization
- we have 40 meters of 1%-5% stringer/disseminated pyrite +/- arsenopyrite associated with massive (1 m) quartz veins and irregular narrow veins and stringers
- a breccia zone from 275 m to 277 m, breccia in 463 hinge zone, and breccia Tim talks about at the 13:19 mark in his interview.
- from the news release on hole 463 we have sphalerite.
From an earlier post I made on sphalerite:
News release, 15 December, of completion of drill hole 22-505 said;
"The 463 Zone is a significant departure in vein style/geometry from one suggested by earlier drill intersections in the vicinity. The “463” intercept is thicker than any other to date and includes the “typical” high-grade vuggy-type veins with abundant VG with 5%-7% accessory boulangerite and sphalerite, as well as brecciated veining with occasional specks of VG with minor boulangerite and sphalerite."
The boulangerite is associated with gold and shown in a photo of a core from hole 18-39.

The sphalerite, also an indicator associated with gold, is much more interesting than the boulangerite for a few reasons. They are associated with large VMS deposits, polymetallic deposits, and deposits with co-credits.
One of the two main places they occur is in volcanogenic massive sulfide ore deposits (VMS ore deposits). "As a class, they represent a significant source of the world's copper, zinc,
lead,
gold and
silver ores, with
cobalt,
tin,
barium,
sulfur,
selenium,
manganese,
cadmium,
indium,
bismuth,
tellurium,
gallium and
germanium as co- or by-products," Wikipedia,
https://en.wikipedia.org/wiki/Volcanogenic_massive_sulfide_ore_deposit
Hole 22-463 hitting an very thick intersection of 12.5 g/t over 39.6 metres of high grade gold is consistent with the presence of sphalerite that is associated with massive VMS ore bodies.

Prospectors gold prospecting on Youtube. At end of video note sample they find containing sphalerite that they do not identify in the video but do identify it in the title of the video. All be it smaller; note that it is the same as in the preceding sample picture.

More: Beyond the sphalerite, the brecciated zones, iron carbonate zones, and pyrite are significant to findings of wide mineralized zones. Tim discusses this in his last "Rocks and Stocks" interview with Allan 11 days ago. At the 13.30 mark he indicated brecciated rocks give wider zones and at 18.50 discusses hole 505 intersecting 100 meters of variable veining all the way down to 159 meters the same as a Fosterville sample pictured laid over a Moosehead drill sample. At 21:10 Tim discusses the iron carbonate. At 22.12 Tim indicates they will sample 300 meters of the 505 core. At 22.56 Tim discusses the disseminated pyrite that is associated with gold.
