Ore shoots continue, in essential parallelism, for several kilometres down plunge; furthermore in some ore trends at Widgiemooltha, ore trends and thickened basal flow channels are mirrored by low-tenor and low-grade'flanking channels '.

This would be termed an " ore shoot . " The existence of the ore shoot could be recognized visually in a tunnel or " drift " excavated along the structure, or by the assaying of rock samples cut from the walls and roof of the tunnel.

As the North Ore Shoot was growing richer with depth, work began in 1943 on the "'North Shaft "', another inclined shaft for winding cages, north from the bottom of Murray's Shaft . It was while this shaft was being sunk that shales from the Skiddaw Group of rocks were first encountered at about below the Lucy Tongue Level.

The work so far accomplished by this company consists of unwatering the Champion shaft to the bottom or 2400'level; reopening and driving the 1000 level 2500 north on the Ural vein to the Nevada City ore shoot; driving the 2400 drift north 3000'; crosscutting on the 1600'level connecting the Ural and Merrifield veins, and a drift which was driven a distance 2500 north of the crosscut on the Merrified vein.

The new company had introduced a system of coordinates to specify locations within the mine, centred on Smith's Shaft . Thus the "'940N Winze "'was north of Smith's Shaft ( even though that shaft did not connect with the 175 Fathom Level . ) The 940N Winze was sunk in 1939 to a new "'200 Fathom Level "'in the heart of the rich North Ore Shoot.
