Alto Metals Ltd (ASX:AME) has fielded further high-grade gold assays that extend the Juno Lode, a recently discovered gold lode within the Lords Corridor at its 100%-owned Sandstone Gold Project in Western Australia.
The reverse circulation (RC) results from extensional drilling mean that high-grade gold mineralisation has now been intersected over a kilometre and the Juno Lode remains open.
New results from 13 extensional RC holes for 2,723 metres include:
- 9 metres at 3.8 g/t gold from 157 metres, including 5 metres at 5.0 g/t from 160 metres;
- 7 metres at 4.4 g/t from 163 metres;
- 12 metres at 2.1 g/t from 160 metres, including 1-metre at 12.4 g/t from 169 metres;
- 17 metres at 1.6 g/t from 159 metres, including 3 metres at 6.3 g/t from 171 metres; and
- 10 metres at 1.3 g/t from 140 metres, including 5 metres at 2.1 g/t from 144 metres.
Potential to continue growing
Alto’s managing director Matthew Bowles said: "These latest results from the recently discovered Juno Lode continue to deliver significant high-grade intercepts.
"Drilling focused on testing the dip and strike of existing mineralisation within the granodiorite damage zone and along the contact of the ultramafic footwall.
"The results have successfully extended the mineralisation at Juno, demonstrating the potential to continue growing this deposit.”

Lords Corridor success
Juno is the second new lode discovered within the Lords Corridor from step-out drilling testing the strike and plunge extensions of the Lord Nelson footwall and hanging wall lodes, following the discovery of the high-grade Orion Lode.
The latest results have successfully extended mineralisation at Juno down dip and along strike; highlighting the overall continuity of the high-grade mineralisation of the initial intersections previously reported.
Importantly, Juno is considered an extension of the mineralised zone below the Lord Nelson pit, which now extends over a 1-kilometre strike and remains open, both along strike to the south and down dip to the west.
Assays pending
Assays are pending from more than 7,500 metres of RC drilling and drilling is ongoing at the Indomitable Camp, within the +20-kilometres NW/SE Indomitable/Vanguard/Havilah Trend, as part of a mineral resource update planned for the second half of this year.
"Further results from drilling at the Lords Corridor are still pending, including the follow-up RC hole testing the down-dip extension to SRC576 which returned 67 metres at 2.3 g/t gold. These results are expected to received shortly,” Bowles said.
"Our next phase of drilling at Indomitable Camp is progressing well, as we continue to focus on growing resources and look forward to sharing assay results from this drilling campaign in the coming weeks and months ahead."
Upcoming newsflow
RC drilling is ongoing at the Indomitable Camp, less than 20 kilometres northwest of the Lords Corridor.
The first 4,850 metres have been completed and these samples are with or in transit to the laboratory for assaying.
Drilling is focused on resource definition and extensional drilling as part of the updated mineral resource work for the second half of this year.
Alto’s major 60,000-metre drilling program planned for 2022 is progressing well, targeting resource growth and exploration as it focuses on existing resources and a number of advanced regional prospects, including:
- Lord Nelson and Juno: first phase of 7,000-metre RC drilling targeting high-grade extensions – completed, initial results announced, further assays pending;
- Indomitable: wide-spaced extensional and resource definition – underway; initial assays pending
- Lord Nelson and Juno: follow up extensional drilling;
- Lords Granodiorite, deeper drilling targeting the margin of the footwall at depth;
- Vanguard, step-out and extensional drilling along the NW/SE trending corridor; and
- Priority regional targets, outside the Alpha Domain.
