Corvus drills 115.82 m of 1.83 g/t Au at Mother Lode
CORVUS GOLD Inc. has released results from the initial five holes from the northern extension of its phase III resource expansion drill program at the 100-percent-owned Mother Lode deposit in Nevada (initial resource announced September, 2018). Stepout holes have outlined potential for an expansion of the Mother Lode gold system to the north with the mineralized zone thickening and grades increasing (see table, highlighted by ML18-093: 115.8 metres at 1.83 grams per tonne gold). Exploration modelling from the continuing program is identifying potential for a new mineralization centre to the north of the currently defined resource, which is scheduled to be tested with an aggressive grid drilling program this year.
Gold mineralization in these northern holes has defined a strong north-south vector along the Fluorspar Canyon fault (FCF) near the intersection with the Tertiary sediments, hosting both the upper sulphide zone and the lower oxide zone. This highly broken, structural intersection has also localized multiple dikes which along with the sediments are a major ore host for the higher-grade mineralization (ML18-093: 115.8 m at 1.83 g/t Au and ML18-83: 65.5 m at 1.53 g/t Au). These results are encouraging for further resource expansion to the north which remains open.
In addition, most of these northern stepout holes ended in thick zones of oxide mineralization as highlighted by hole ML18-092 (24.4 m at 1.22 g/t gold) which ended in oxidized carbonates with a grade of 3.36 g/t gold. Further follow-up drilling will target the thickest and highest-grade part of the FCF target to the north of ML18-092 and ML18-093 as well as up and down dip.

Jeff Pontius, president and chief executive officer, said: “We are excited about the thicknesses of both sulphide and oxide zones to the north which appear to be indicating a new centre of mineralization similar to the current known deposit to the south which is encouraging for an expansion of the Mother Lode deposit. We have been drilling the Mother Lode deposit for the past 18 months and have yet to find the edge of it in any direction. With the initial resource only including drilling through mid-July, these and earlier results point to continued expansion potential. Our evolving understanding of the overall Mother Lode sediment-hosted system is helping define other new targets throughout our large 122 square km land package.”
We seek Safe Harbor.
