21-1352 MBX Deep
Section E
Resource infill of the
MBX footwall zone below
the 2020 ultimate pit
boundary, along strike
between 21-1341 (85 m
NNE), 21-1348 (90 m
SE), and 19-1186 (85 m
ENE). Drilling also
targeted the new Lower
Porphyry zone at depth.
21-1353 MBX Deep
Section A and B
Resource infill of the
MBX footwall zone below
the 2020 ultimate pit
boundary, between 21-
1308 (located ~100 m
west) and 18-1070
(located ~110 m
northeast). A possible
Saddle fault intersection
is expected at ~95 m.
Drilling also targeted the
new Lower Porphyry
zone at depth.
21-1351 MBX Deep
Section B
Infill hole targeting the
MBX footwall zone below
the 2020 ultimate pit
boundary between drill
holes 20-1269 and 21-
1308, testing
mineralization up to
0.25% CuEq (2019 Block
Model) to 260 m with a
higher-grade section up
to 0.44% CuEq expected
from 0-80 m where it
collars into the MBX
stock.
