Riedel Resources Limited announced assay results from a reverse circulation (RC) drill program at its Kingman Project in Arizona, USA, have continued to identify high grade zones of mineralisation. Riedel's drill program primarily focussed on the historic Tintic mine area, where mining occurred in the late 1800's and early 1900's and where drilling in early 2021 intersected multiple high-grade veins. The project was mined predominantly for high-grade gold and silver from the 1880s until the early 1940s - which coincided with the outbreak of WWII.

Following limited drilling near Tintic in the 1990s, 11 diamond holes were drilled on the property in late 2019 which intersected multiple zones of high-grade gold, silver and lead from shallow depths, confirming the extensive mineralisation potential of the area. In April 2021, Riedel completed a 5,000m RC drill program over several historic mine areas on the property, including at Tintic, Merrimac, Arizona Magma and Jim's. This drilling returned numerous high-grade gold and silver assay results including 3.8m at 98.9g/t gold and 151g/t silver from 20.6m at Tintic. In addition, it confirmed a 1.8km long exploration target associated with the historic Jim's mine to host significant gold, silver, zinc and lead mineralisation as shallow as 1.5m below surface.

The Kingman Project has seen minimal modern exploration. Riedel's RC drill program completed in April 2021 was its first at Kingman, where it is looking to acquire up to an 80% interest in via its December 2020 Agreement with Flagstaff Minerals Limited and Flagstaff Minerals (USA) Inc.
