Alderan launches drill program at Mizpah oxide gold deposit in US

Alderan Resources (ASX:AL8) announces it has started its planned 20-hole (2,000m) reverse circulation (RC) drilling program at Mizpah oxide gold deposit at its Detroit project in the Drum Mountains region of western Utah, US.

The company reports the program’s initial focus will be confirming ‘high-grade’ near-surface oxide gold mineralisation.

Mizpah is located only 2km north of the historical Drum oxide gold mine which Alderan drilled in H1 2022 with all verification holes intersecting gold including 6.6m @ 2.5g/t Au within 17.8m @ 1.7g/t Au in hole 9DD22-003.

Alderan notes that Mizpah, which was drilled in the 1980s, sits in the same rocks as Drum but unlike the historical mine, it was never developed into a mining operation hence gold mineralisation remains from surface.

Historical drilling results include 40 holes which have a final assay grading more than 0.5g/t Au and 20 of these holes have last assays grading more than 1.0g/t Au.

The highest final assay down a historical hole is 9.1g/t Au in hole MZ-87-52.

Alderan’s historical drill hole constrained modelling of the Mizpah’s deposit indicates exploration potential for approximately 40-100,000oz of gold grading at about 0.4-0.8g/t Au, however the deposit is open down dip to the southwest and along strike to the north and south.

It should be noted that this exploration potential quantity and grade is conceptual in nature and there has been insufficient exploration to estimate a Mineral Resource and that it is uncertain if further exploration will result in the estimation of a Mineral Resource.

Alderan drillholes DD-MZ-20-006 and 3DDMZ-001 which intersected 83m @ 0.41g/t Au and 69.5m @ 0.18g/t Au respectively are located 190m and 350m to the west-northwest of the deposit and indicate that Mizpah’s mineralising system is ‘significantly larger’ than historically outlined.

Commenting on the works program, Alderan Managing Director Scott Caithness said: “Mizpah is an undeveloped oxide gold deposit with mineralisation open from surface and dipping gently at approximately 20 degrees to the southwest.

It sits in the same rock units as the historical Drum gold mine which lies only 2km to the south and produced 125,000 oz of gold in the 1980s.

“Historical Mizpah holes end in grades up to 9.1g/t gold, primary gold potential has never been tested”

Historical Mizpah holes end in grades up to 9.1g/t gold, primary gold potential has never been tested and Alderan’s drilling suggests that the mineralised system is much larger.

Securing the reverse circulation rig for the Mizpah drilling program is a great result as it will enable Alderan to rapidly and cost effectively delineate the gold mineralisation. Drilling aims to intersect near-surface, high-grade oxide mineralisation before testing for deeper down dip extensions.

Following the lessons learned from our recent drilling at Drum, Alderan also plans to drill a number of angled holes aimed at testing structures which have potential to host high gold grades.”

Alderan’s Mizpah drilling program is expected to be completed in September with all holes logged and samples submitted to the laboratory for gold analysis. Results are expected early in Q4 2022.
