• Dateline Resources receives diamond drill results for CM24-16 and CM24-15
  • Both holes intersect thick, high-grade gold outside of the known sedimentary breccia unit
  • Additional drilling is planned to test the extents of this mineralisation


Special Report: Dateline Resources has received more monster drill hits from the +800,000oz Colosseum project, including 88m @ 4.18g/t Au.

Dateline’s (ASX:DTR) Colosseum gold project in San Bernardino County, California sits within the Walker Lane Trend, home to several substantial discoveries including Equinox Gold’s 6.5Mt Castle Mountain gold mine about 50km to the southeast of Colosseum.

Another 10kms away is America’s only rare earths mine, the MP Materials owned Mountain Pass Mine, responsible for delivering about 15% of global rare earth supply.

DTR has been working hard at proving up the resource base at the project, which currently holds a 20.9Mt resource @ 1.2 g/t for 813,000oz of contained gold.

Drilling has so far returned numerous high-grade hit such as the monster 76.2m @ 8.62 g/t gold intersection in hole CM23-08 and the more recent 70.1m @ 6.53 g/t gold assay in CM23-14.


Big hits continue

Now, results have been received for part of the diamond drillhole, CM24-16, as well as for CM24-15.

88m @ 4.18g/t Au was intercepted in diamond drill hole CM24-16, including 22.8m @ 8.17g/t Au. 19.8m @ 4.19g/t Au was intercepted in diamond drill hole CM24-15.

Interestingly, drill holes intersected high-grade mineralisation in the felsite unit rather than the sedimentary breccia that has been the primary target to date.

“This development is significant, and the geology model will be updated accordingly,” DTR says.

DTR says the high-grade mineralised section of CM24-16 (the 22.8m intersection) is an encouraging sign for the expanded potential economic volume of the deposit.

Other highlights of the recent drilling include 70.1m @ 6.53g/t gold including 25.9m @ 15.31g/t gold from 254.5m; and 100m @ 4.16g/t gold.

Additional drillholes are now planned to test the extents of this felsite breccia mineralisation.


10-hole RC drilling program

“The drilling program has been accelerated and expanded at Colosseum,” DTR managing director Stephen Baghdadi says.

“CM24-16 intersected a wide 88m @ 4.18g/t Au in the upper and lower part of the drill hole in the felsite breccia unit, which is an encouraging development because the felsite breccia unit is the most voluminous rock type at the Colosseum.”

Reverse circulation drilling is also underway at the project, with one drillhole completed.

Drill samples have been sent for analysis while the RC rig focuses on a program of infill drilling within high-grade zones to improve mineral resource categorisation to measured or indicated ahead of mine planning studies.

An initial 10 hole RC program is planned.
