Peregrine Gold (ASX:PGD) has recovered visible gold from two orientation bulk samples collected adjacent to the Peninsula prospect at its Newman Gold and Iron Ore Project in Western Australia.
The company extracted approximately 500kg to 700kg of paleo gravel material from each pit and processed it using dry blowing techniques.
Pit one, located 110m south of the Peninsula auriferous quartz vein, yielded an estimated 5.3g of gold including a 48g ironstone-quartz-gold specimen. Pit two, positioned 20m south of the vein, returned approximately 7g of gold recovered as smaller pieces.
The bulk sampling program aimed to confirm the effectiveness of dry blowing techniques for gold recovery from paleo gravels and build confidence in the potential of gravels within mining lease application M52/1097, known as the Capricorn prospect.
Recent channel sampling of paleo gravels approximately 400m south of the bulk sample sites returned peak results of 13.5 grams per tonne gold (Au) and 1.8g/t Au, confirming the presence of gold-rich gravels in the area.
Technical Director George Merhi says the orientation bulk sampling program confirmed the paleo gravels are highly auriferous and that dry blowing techniques can effectively extract gold.
“This successful orientation bulk sampling has provided the confidence for Peregrine to advance the paleo gravel project south of the three special prospecting licences to include bulk sampling, subject to lodging a program of works and completing heritage work.
“The inferred older paleo gravel unit could, if confirmed auriferous, add significantly to the gold footprint at the Capricorn prospect.”
The company has submitted 22 additional channel samples collected across the inferred older paleo gravel unit to Intertek for geochemical analysis. Should these samples return anomalous gold results, Peregrine says the collective width of auriferous paleo gravels across the Capricorn prospect could expand to approximately 280m.
Peregrine intends to undertake further bulk sampling to assess gold grades within the inferred paleo gravel unit and complete additional trial dry processing. It will also prepare a mining development and closure plan to support small-scale mining operations, with heritage work scheduled for the end of October.
Peregrine Gold is a mineral explorer focused on gold, lithium, and iron ore assets in the Pilbara region of WA.
