Riedel lauds potential of high-grade Arizona gold zone

Riedel Resources has extended the high-grade gold zone of its Tintic prospect at its Kingman project in Arizona after positive results from its ongoing infill and extensional drill campaign.


The company says its latest assays have extended mineralisation by about 50m along strike and 50m down dip to the north and east of previous drilling. It believes Tintic is the biggest gold zone within its Kingman project.


Recent drilling has targeted the strike and down-dip extensions in the northern area of the prospect, in addition to resource infill drilling. The extension program has thrown up some solid results, with highlights including a 0.76m hit grading 12.5 grams per tonne gold, 41.8g/t silver, 0.86 per cent lead and 1.8 per cent zinc from just 31.92m. The same hole also produced 2.28m going 3.9g/t gold, 38.68g/t silver, 0.77 per cent lead and 0.35 per cent zinc.


Riedel’s infill program is aiming to produce a maiden mineral resource at Tintic before the end of the year. Highlights include a 1.52m hit going 15.6g/t gold, 160.5g/t silver, 1.02 per cent lead and 0.38 per cent zinc from 40.28m. A second hole recorded a 5.32m intercept at 2.37g/t gold, 329g/t silver, 0.28 per cent lead and 0.4 per cent zinc.

It is worth emphasising 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. 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 Riedel Resources chief executive officer David Groombridge

Kingman sits about 90 minutes south of Las Vegas, in an area mined for high-grade gold and silver from the 1880s. However, the area has experienced limited exploration and drilling since – some in the 1990s and some three years ago when 11 diamond drill holes intersected high-grade zones of gold, silver and lead from shallow depths.


Riedel picked up the project through an earn-in agreement with Flagstaff USA in October, 2020. It almost immediately got to work by drilling 104 RC holes in 2021 at the Tintic, Merrimac, Arizona Magma and Jim’s historic mines and followed up with 20 diamond holes last year.


Previous drilling at Tintic returned some impressive shallow results including a 3.8m hit at a whopping 98.9g/t gold and 151g/t silver from just 20.6m. Additional shallow drill highlights from the prospect include 1.5m going 39.3g/t gold and 323g/t silver from 37.3m and 5.3m grading 18.1g/t gold and 24g/t silver from just 23.6m.


Deeper assays also returned positive results with a 3.8m hit at 18.1g/t gold and 201g/t silver from 85.4m, in addition to 4.6m reading 8.39g/t gold and 39g/t silver from 100.6m.


The company has completed about half of its planned 7000m campaign at Tintic, with assay results from the southern area still pending. Management believes the prospect is shaping up as a potentially large zone of gold-silver mineralisation.


If the upcoming results from further extensions to the south can deliver similar figures, Riedel could be looking at a significant resource that would etch its name into Arizona’s rich mining history.
