London-based precious and base metals exploration and development company Greatland Gold has confirmed the presence of mineralisation over several kilometres of strike at the company’s fully owned Panorama gold project, in the Pilbara region of Western Australia.
Field reconnaissance activities, which started in late June and are focused on Archean lode gold mineralisation, have located several gold nuggets in thin soil over several hundred metres of strike. This confirms the presence of gold mineralisation along the mineralised zone, according to a company statement released last month.
With gold nuggets being found further south along strike than previously identified, this extends the strike extent of the mineralised trend from 3.2 km to 4.3 km.
“The discovery of numerous gold nuggets in multiple locations within the first week of the new field campaign at Panorama represents a very exciting start to this campaign and further confirms our belief in the significant potential of this project,” states Greatland Gold CEO Gervaise Heddle.
Moreover, the dual geochemical and geophysical campaign that is being conducted at Panorama illustrates an improvement in the scale of exploration that was previously conducted on this project, says Heddle.
He also reiterates the importance of these early results in supporting the company’s decision to accelerate the pace of exploration activity at this gold target.
“We look forward to providing further updates as the exploration campaign progresses, including results from soil and rock chip sampling and the aeromagnetic survey.”
The Panorama project consists of three adjoining granted exploration licences located in the Pilbara region of northern Western Australia. The licences cover a total area of about 155 km2 and are prospective for gold and base metals mineralisation.
The geology of the area is primarily greenstone and granite of the Archean Pilbara Craton in northern Western Australia, and younger overlying sedimentary and volcanic sequences. As such, the project is prospective for Archean lode gold mineralisation, as well as ‘conglomerate’ style gold mineralisation.
Greatland Gold completed a detailed review of historic work at Panorama, which revealed many rock chip samples with an elevated gold response from within the project area. The most significant samples identified to date lie along a north-south trending zone about 3.2 km long with the rock chip results including 66 g/t, 14.5 g/t, 4.1 g/t, 2.1 g/t and 1.1 g/t gold. The geological setting is a prominent ridge marking the structural contact of basaltic and ultramafic rocks of Archean age.
Greatland conducted sporadic rock chip sampling along this zone in 2017 with results that showed 18.45 g/t, 1.82 g/t, 0.71 g/t, and 0.61 g/t gold over about 3.2 km of strike. This confirmed the presence of gold mineralisation and the high potential of the zone.
The mineralised zone, which is hosted in Archean basement, remains open to the south-west and will require further reconnaissance activities, as well as systematic, grid-based surface geochemical sampling.
In addition, a detailed and low-level aeromagnetic survey that covers the entire Panorama project area was also scheduled to begin last month.
Greatland Gold has also commissioned a detailed, low-level airborne magnetic survey to cover the whole area. This survey includes about 8 000 line kilometres at a line spacing of 50 m, with an estimated mean terrain clearance of 40 m.
