Alto Metals Limited (ASX: AME) has announced significant shallow gold hits including 28m @ 2.8 g/t gold from 48m from the new lode just 200m south of the Lord Nelson pit within the Company’s flagship Sandstone Gold Project in WA.
The company reported that the assay results from a further 1,974m RC drilling have been received.
Significant results from the shallow infill drilling (on 40m spacing) targeting the new lode south of Lord Nelson pit includes 28m @ 2.8 g/t gold from 48m, including 4m @ 7.4 g/t gold from 56m; 16m @ 3.7 g/t gold from 108m, including 4m @ 8.2 g/t gold from 116m; and 16m @ 1.6 g/t gold from 24m, including 4m @ 3.8 g/t gold from 36m.
The company said that the wide spaced (80m step out) drilling extends strike of the new lode over 300m. Significant new 80m step out drilling results include 8m @ 2.4 g/t gold from 156m.
AME said that the mineralisation remains open along strike, down dip, and down plunge.
These latest results followed up on the shallow results announced on 27 July 2020.
The company noted that the recent high-grade gold intersections in oxide, transitional and primary zones have extended the mineralised footprint at Lord Nelson to approx. 1,000m.
AME reported that a total of approximately 3,500m of RC drilling, of a planned 10,000m program, has now been completed since early July 2020.
The company said that drilling is ongoing at Lord Nelson, with a further 2,000m of RC drilling currently underway targeting depth extensions beneath the pit and strike extensions of the new lode to the south.
Alto’s Sandstone Project covers ~80% (800km2) of the historic Archaean Sandstone Goldfield 600km north of Perth in the East Murchison Mineral Field of Western Australia and is centred on the small township of Sandstone.
The numerous former open pits, prospects, and gold occurrences now owned by Alto include Lord Nelson, Lord Henry, Havilah, Bull Oak, Vanguard, Ladybird, Maninga Marley, Sandstone North, Oroya, Tiger Moth, Musketeer, Piper, and Bulchina.
The Lord Nelson deposit occurs along the north-south trending Trafalgar shear zone. The Lord Nelson deposit was previously mined by Troy Resources NL down to 90m depth and produced 207koz at 4.6 g/t gold.
Alto’s current Inferred Mineral Resource Estimate (JORC 2012) for Lord Nelson is 1,820kt @ 1.9g/t gold for 109,000oz and forms part of the Company’s total global Indicated and Inferred (JORC 2012) Mineral Resource Estimate for the Sandstone Project of 6.2Mt @ 1.7g/t gold for 331,000oz.
Drilling at Sandstone
Alto Metals had recently commenced drilling at Sandstone. The company said that a total of approximately 3,500m of RC drilling of the planned 10,000m program has now been completed, and another 2,000m is currently underway.
AME has now announced the results for a total 1,974m of RC drilling, (15 holes), including further infill and step out at Lord Nelson and limited drilling at Bulchina South and Bollinger.
New gold lode intercepted
The company announced that the infill drilling south of the Lord Nelson pit, to close the drill space to 40m over a portion of the southern extension, has intercepted the new gold lode at the predicted lode position and confirmed the continuity of mineralisation.
AME reported that a step-out drill hole has confirmed mineralisation of the new lode extends a further 80 metres and remains open.
The company announced that this new lode appears to be a repeat of Lord Nelson (which produced 207,000oz at 4.6g/t gold mined down to a depth of 90m) and is located 200m to the south, with a moderate westerly dip and gently plunging southerly shoot.
Other previous results from the new lode south of Lord Nelson include 20m @ 2.3 g/t gold from 64m (SRC183), within a broader zone of 36m @ 1.6 g/t gold from 48m – 27 July 2020; 4m @ 4.1 g/t gold from 112m (SRC182) – 27 July 2020; 12m @ 1.6 g/t gold from 140m (SRC187) – 29 July 2020; 23m @ 3.8 g/t gold from 106m (SRC168), including 6m @ 4.6 g/t gold from 106m, and 10m @ 4.5 g/t gold from 116m – 2 April 2020 ; 10m @ 4.1 g/t gold from 34m (SRC169) including 2m @ 12.8 g/t gold from 36m – 2 April 2020; and 12m @ 3.4g/t gold from 66m (SRC148) – 22 July 2019.
The Company reported that its immediate focus is on Lord Nelson, the new lode, and the southern extension corridor. However limited drilling was required to be completed at Bulchina South and Bollinger to meet statutory expenditure requirements.
Lord Nelson pit
Significant results from the shallow infill drilling (on 40m spacing) targeting the new lode south of Lord Nelson pit include 28m @ 2.8 g/t gold from 48m (SRC191), including 4m @ 7.4 g/t gold from 56m; 16m @ 3.7 g/t gold from 108m (SRC192), including 4m @ 8.2 g/t gold from 116m; and 16m @ 1.6 g/t gold from 24m (SRC190), including 4m @ 3.8 g/t gold from 36m.
Significant new 80m step out drilling results include 8m @ 2.4 g/t gold from 156m (SRC197).
The company said that four-metre composite assays confirm continuity of the shallow gold lode south of the Lord Nelson pit and equally importantly, extension along the Lord’s corridor.
Bulchina South and Bollinger
Alto Metals said that the drilling at Bollinger returned encouraging results, including a very shallow intercept of 28m @ 2.12 g/t gold from 4m (including 4m @ 6.24 g/t gold from 24m) and 12m @ 1.27 g/t gold from 56m (SRC200). AME said that the drilling at Bulchina South encountered low level gold in both holes drilled.
The company announced that the next phase, planned for 2,000m of RC drilling is currently underway targeting depth extensions beneath the Lord Nelson pit and strike extensions of mineralisation of the new lode.
AME said that the remaining drilling of approximately 4,500m of the proposed 10,000m program is currently planned to include additional infill and extension drilling both along strike and at depth at Lord Nelson; testing of additional repeat lode targets in the Lord’s Camp area; and regional targets along the Edale Shear, including Chance prospect.
Alto’s Managing Director Matthew Bowles said: “This new lode is emerging as a repeat of Lord Nelson and these latest outstanding results continue to support our view of the likelihood of a much larger mineralised gold system.
Drilling has now demonstrated the continuity of the new mineralised lode, which is already known to extend over 100 meters down dip and over 300m strike and remains open.
RC drilling is ongoing at Lord Nelson, targeting high-grade gold mineralisation beneath the pit and further extensional drilling of this new lode. We remain focused on continuing exploration, despite the current corporate distractions, and look forward to updating shareholders on further drilling results”.
