Quick question — was the early signal over Voisey’s Bay first identified on GEOTEM or INPUT, and what were the survey specs? I’m tidying a mineral exploration case-study slide and want to cite the original line spacing and flight height; I recall about 200 m lines at about 120 m AGL with a strong late-time response.
And it was GEOTEM, not INPUT, with “200 m lines at about 120 m AGL,” and the eye-catcher was the late-time channels; I’ve got 25 Hz noted from the Geoterrex report. From experience, spell out the late-window range you plotted (around 3–8 ms) so the case study shows why it popped — an earlier, coarser INPUT pass didn’t really light it up. Do you want the exact gate schedule from the 1994 report?
Agree with @jgrayson27 on GEOTEM/25 Hz; one handy add is that follow-up included about 100 m infill and a low-base 12.5 Hz refly to punch up the late-time — like turning up the subwoofer on VB-1. Do you want the late-channel window timings they cited?
From my field notes, VB-1 read best on Z with picks in the far-off gates; we confirmed it with a quick 12.5 Hz refly on the strongest lines. > on VB-1. Do you want the late-channel window timings they cited? I can pull the gate edges for you, @ethan_p85, and note the 120 m drape didn’t always match bird clearance in the valleys — want those numbers?
