Horizon Minerals Ltd (ASX:HRZ) has discovered new high-grade mineralisation in its first aircore drilling program at Windanya Gold Project around 45 kilometres north of Kalgoorlie in WA’s Goldfields region.
The results of up to 2 metres at 26.68 g/t gold from 35 metres including 1-metre at 39.71 g/t from 35 metres and 1-metre at 13.66 g/t from 36 metres in hole WAC20019 add impetus to Horizon's aggressive exploration program at satellite prospects around Kalgoorlie-Boulder.
This exploration is aimed at providing feed for the company's proposed Boorara processing plant being assessed as part of a consolidated feasibility study.
Drilling comprised 57 aircore holes to a maximum depth of 76 metres which tested high priority new discovery targets between the 100%-owned Capricorn prospect and the Eureka mine.
“Fantastic result”
Managing director Jon Price said: “To have hit such significant mineralisation in the first aircore program at Windanya is a fantastic result and testament to the quality of the target generation work completed in 2020 and full credit goes to our first-class exploration team.
“This region has had very limited modern exploration and is surrounded by quality large scale deposits to the north and south."
Discovery hole
Discovery hole WAC20019 intersected shallow, high-grade mineralisation within 35 metres of weathered quartz stockwork.
Other strong results include:
- 1-metre at 2.59 g/t from 40 metres and 1-metre at 4.88 g/t from 46 metres; and
- 2 metres at 4.99 g/t from 67 metres.
This initial drilling confirms the new discovery sits within a 3.3-kilometre-long mineralised trend extending north and south with multiple targets yet to be tested.
The prospect, named Gemini, will be followed up with reverse circulation (RC) drilling with further results expected in the June quarter of 2021.
"Exciting region"
Price said: “The aircore program at Windanya will soon be followed up by RC drilling and we look forward to releasing further results from this very exciting region in coming weeks.
“Windanya and Baden Powell are now demonstrating the potential for new resources to be established within easy trucking distance of the proposed Boorara processing plant being assessed as part of the consolidated feasibility study.”
Further results pending
The Windanya group of tenements are on the western limb of the Mt Pleasant Dome, west of the Bardoc Tectonic Zone.
Windanya’s stratigraphy comprises a northwest striking sequence of ultramafics (Siberia Komatiite), overlain by mafic volcanics and intrusives (the Big Dick Basalt, Mt Pleasant Sill (dolerite) and the Bent Tree basalt).
Further aircore results are pending and drilling will continue across the new mineralised trend as part of the company's 50,000-metre 2021 exploration drilling program.
