- Intrepid Metals (INTR) completes geophysical survey at Tombstone South Property
- The geophysical survey consisted of one line using standard 7-electrode dipole-dipole arrays with dipole lengths of 450 meters, which may provide over 1000-meter depth penetration
- The Tombstone South Property is located approximately 5.6 kilometres southwest of the town of Tombstone, Arizona
- The property consists of 39 unpatented federal mining claims and six Arizona State prospecting permits comprising a total of 1,335 hectares
- The Cretaceous-Paleozoic contact zone on the property, including its proximity to low-grade porphyry copper deposits and high-grade silver deposits
- Intrepid Metals Corp. (INTR) is in the grey, trading at C$0.16 at 3:40 pm ET as of May 9
Intrepid Metals (INTR) has completed a ground-based geophysical survey on its Tombstone South Property in Cochise County, Arizona.
An induced polarization geophysical survey was completed by Zonge International, Inc., which previously conducted a Natural Source Audio-Frequency Magnetotelluric survey (NSAMT) on the property in 2007.
“Following the completion of the change of business and the closing of our recent financing, we are excited to start groundwork at Tombstone South in preparation for our drill program in the months ahead,” states Ken Brophy, Company CEO.
“[…] it was recommended we complete a large dipole IP geophysical survey in an attempt to directly target concentrations of iron and lead sulphides, consistent with Carbonate Replacement deposits and skarn mineralization analogous to South 32’s Taylor Deposit,” added Brophy.
The geophysical survey consisted of one line using standard 7-electrode dipole-dipole arrays with dipole lengths of 450 meters, which may provide over 1000-meter depth penetration to target polymetallic CRD’s in the Cretaceous rocks of the Bisbee Group and skarns at the Cretaceous – Paleozoic contact. These two exploration targets exist at Tombstone South.
The Tombstone South Property is located approximately 5.6 kilometres southwest of the town of Tombstone, Arizona, the USA, which occupies the center of the historic Tombstone Mining District.
The property is easily accessible via two hours of driving on a paved highway from Tucson, Arizona and is approximately 113 km southeast of Tucson, Arizona.
The property consists of 39 unpatented federal mining claims and six Arizona State prospecting permits comprising 1,335 hectares.
The central Tombstone District is well-known for high-grade silver/lead/zinc replacement bodies, fissures and veins that have yielded a historical production (the 1880s to 1930s) of over 30M ounces of silver.
Two exploration targets exist at Tombstone South. The first is structurally and stratigraphically controlled Pb-Zn-Ag CRD mineralization in Cretaceous Bisbee Group strata, analogous to the historically mined orebodies in the Tombstone District.
The second is deeper polymetallic (silver/lead/zinc) type skarns at the Cretaceous-Paleozoic contact.
This stratigraphic horizon hosts the Taylor silver/lead/zinc deposit in southern Arizona, which was bought for US$1.3B in 2018 by South 32.
The Cretaceous-Paleozoic contact zone on the property, including its proximity to low-grade porphyry copper deposits and high-grade silver deposits, presents a very favourable setting for Taylor deposit style mineralization.
