Rumble Resources Ltd (ASX:RTR, OTC:RTRFF) has resumed reverse circulation (RC) drilling at the growing Earaheedy Base Metals Project, 110 kilometres north of Wiluna in Western Australia, to test multiple new gravity lows along the 9-kilometre Navajoh Southeast Trend.
An airborne gravity survey flown late last year identified a strong association between these gravity lows and higher-grade zinc-lead feeder faults at the Tonka and Navajoh prospects.
The Navajoh Southeast Trend is southeast of the Tonka-Navajoh mineralised footprint.

“Exceptional near-term potential”
"We are excited to get back into discovery mode and announce the resumption of drilling operations,” RTR managing director Shane Sikora said.
“We have a high-impact program planned that will be focused on testing the high-grade feeder targets along the Navajoh Southeast Trend.
“We will also have a specific focus on targeting high-grade Mississippi Valley Type (MVT) discoveries within the interpreted high-angle feeder structures.
“The Earaheedy Project has exceptional near-term growth potential and we are eager to advance what we believe will become a world-class base metal asset.”

First deep drill hole
RTR has awarded a diamond drilling contract targeting high-grade MVT-type mineralisation below the Chinook Deposit.
The cost of the initial 700 metre-deep hole program will be co-funded by the Exploration Incentive Scheme (EIS) grant of up to $150,000.
This will be RTR's first deep diamond drilling within Earaheedy and has been positioned to test beneath Chinook's extensive 8-kilometre by 2-kilometre mineralised footprint, where the potential for structurally-hosted high-grade MVT deposits is considered high.
Tier-1 scale potential
RTR believes the Earaheedy Project has exceptional growth potential as only two of the five identified mineralised styles have been explored, while less than 35% of the 45-kilometre Navajoh Unconformity Unit has been tested by drilling.
The company plans to focus on extending existing and discovering new high-grade feeders such as Kalitan, Chikamin, Colorado and Magazine within the E69/3464 tenement and the untested Sweetwater and Navajoh Southeast trends within E69/3787 and E69/3862.
It also plans to commence preliminary scoping level studies on the Chinook, Tonka and Navajoh deposits in the coming months.
