Riedel Resources’ latest drilling results at the Tintic prospect at its Kingman gold project in Arizona, USA, have confirmed a northern extension to the high-grade zone.

Tintic is the largest gold zone within the project, and current resource drilling has extended mineralisation by approximately 50m along strike and 50m down dip to the north and east of previous drilling.

Notable results include:

  • 52m at 15.6g/t gold, 160.5g/t silver, 1.02% lead, 0.38% zinc from 40.28m (RC23TT007)
  • 32m at 2.37g/t gold, 329g/t silver, 0.28% lead, 0.40% zinc from 60.04m (RC23TT039);
  • 76m at 12.5g/t gold, 41.8g/t silver, 0.86% lead, 1.80% zinc from 31.92m (RC23TT044);
  • 28m at 3.9g/t gold, 38.68g/t silver, 0.77 % lead, 0.35% zinc from 41.04m (RC23TT044);
  • 76m at 3.91g/t gold, 163g/t silver, 0.43% lead, 0.17% zinc from 57.76m (RC23TT045);
  • 52m at 1.73g/t gold, 584g/t silver, 0.72% lead, 1.17% zinc from 38.76m (RC23TT006); and
  • 52m at 5.14g/t gold, 11.97g/t silver, 0.45 % lead, 0.36% zinc from 47.88m (RC23TT005).


The drilling has consistently intersected two parallel lodes that remain continuous between sections and down-dip – and importantly, remains open.

Riedel Resources (ASX:RIE) says Tintic is shaping up as a very extensive zone of shallow high-grade gold and silver mineralisation.

Potentially a very large gold-silver zone

“These first RC drill results from Tintic continue to provide strong support and confidence in the geological continuity and consistency of the high-grade gold-silver mineralisation at very shallow depths,” Riedel CEO David Groombridge said.

“Step out extensions to the northwest in RC23TT044 and RC23TT045 confirm mineralisation extends along the structural Tintic trend and demonstrates that the system remains open.

“Along with thicker intercepts observed in RC23TT039 down-dip, the northern area is unexplored.

“It is worth emphasizing that Tintic is shaping up as a potentially very large zone of gold-silver mineralisation.

“It is now some 700m in length and up to 200m in width and continues to grow with each drill program.”

Shallow deposits perfect for open pit mining

 In addition to resource infill drilling, the company’s drilling has targeted the strike and down-dip extensions in the northern area of the deposit, and all mineralisation to date has been intercepted predominantly within 50m vertical depth of surface.

Two lodes were intersected with results including:

  • 76m at 12.5g/t gold, 41.8g/t silver, 0.86% lead and 1.80% zinc from 31.92m (RC23TT044);
  • 28m at 3.9g/t gold, 38.68g/t silver, 0.77 % lead and 0.35% zinc from 41.04m (RC23TT044); and
  • 76m at 3.91g/t gold, 163g/t silver, 0.43% lead and 0.17% zinc from 57.76m (RC23TT045).

“The very shallow nature, when combined with its ever growing footprint, make it potentially a very exciting open pit mining opportunity with high grades seen in drilling commencing at or very near surface,” Groombridge said.

Drilling and MRE work ongoing

These are just the first results from a planned 7,000m program with circa 3,500m drilled to date.

RC drilling is currently finalising the phase-1 MRE program at Tintic South before the focus shifts to testing the Tintic to Jim’s Trend to the southeast, and some exciting early-stage prospects.

Follow-up infill drilling to the north will be completed in August 2023 with the objective of identifying additional mineralisation to be included in the Minerals Resource Estimate (MRE) scheduled for late 2023.
