Alderan completes two holes targeting Drum and Mizpah gold
HIGHLIGHTS
only | • Alderan completes two holes targeting the Drum and Mizpah gold deposits in its drilling | ||
programme at the Detroit copper and gold project in Utah, USA. | |||
• Drum historical oxide gold mine produced 125,000oz and is geologically open along strike | |||
and down dip. It has not received any modern exploration since mining ceased in 1989. | |||

Alderan Resources Limited (ASX: AL8) (Alderan or the Company) is pleased to provide an update on the planned 10- hole drilling programme at its Detroit Project, located in the Drum Mountains region of western Utah, USA, which recommenced in January 2022.
Two holes have been completed, hole 9DD22-001 at the Drum mine and hole 3DD22-001 at Mizpah. The Drum hole aims to verify a zone in the East Pit including historical drill hole YC-16 which intersected 56.4m @ 1.8g/t Au from 44.2m downhole. The Mizpah hole, one of the original Stage 1 holes, was planned to test the down dip extension of mineralisation in Alderan's hole DD20M-006 which intersected 83m @ 0.41g/t Au including 6.9m @ 1.98g/t Au.
Alderan Managing Director, Scott Caithness said: "It is exciting to be drilling to increase the size of two known gold deposits which have not been explored since the mid-late 1980s. Historical work on both prospects focussed on delineating near surface oxide gold deposits with the average drill hole depth of less than 50m at Drum and 30m at Mizpah. Both oxide deposits are open down dip and along strike and the potential for primary mineralisation below the oxide remains untested.
ASX ANNOUNCEMENT
22 February 2022
"With oxide gold deposits in neighbouring Nevada mined to cut off grades of 0.15-0.2g/t Au and both deposits being open, Drum and Mizpah have the potential to be significantly larger than what has been delineated in the onlypast. Our initial focus is to verify historical drill results and then confirm upside potential with first results expected
in March."
Detroit Drilling Update1
Alderan re-commenced its drilling programme at Detroit following rig maintenance and a break over Christmas- New Year. Drilling will focus on the Drum Gold Mine where 10 holes are planned totalling approximately 1,200m. Three holes are also planned at Mizpah totalling approximately 300m.
useDrilling at Drum aims to verify historically drilled gold mineralisation and also test for new mineralisation. A key focus of testing for new mineralisation will be drilling below the West Pit into the down-dip extensions of the Tatow unit, the prime ore horizon in the East Pit.
Drill hole 9DD22-001 completed at a depth of 117.95m was designed to test for gold mineralisation in the zone s rrounding historical hole YC-16 which intersected 56.4m grading 1.8g/t gold from 44.2m downhole in Tatow nit sediments. Modelling suggests approximately 10-20m of the YC-16 intersection which includes grades up to 7.1g/t Au remained as residual gold mineralisation below the final pit bottom when mining ceased at Drum in
1989. Figure 1 shows the location of completed and planned holes at Drum.
personalAt Mizpah, drill hole 3DD22-001 has been completed at a depth of 164.89m. This hole is a ~350m step-out to test for down dip extensions to the west of Alderan's hole DD20M-006 which intersected 83m @ 0.41g/t Au
including 6.9m @ 1.98g/t Au during maiden Detroit drilling in 2020 (see Figure 2).
Alderan has submitted samples from both holes for analysis and results are expected in March 2022. Table 1 below summarises the targets to be tested by each completed and planned hole.
Next Steps
Alderan awaits assays for drill holes 9DD22-001 and 3DD22-001 and also final assays for holes 7DD21-003,6DD21-004,6DD21-005 and 6DD21-006 which were completed on its Detroit project in Q4 2021. Alderan released assays for a 21m section of hole 6DD21-004 and a 31.8m section of hole 6DD21-005 in an ASX announcement on 30 December 2021.
Additional drilling at Drum and Mizpah as per the plan outlined in Table 1 will commence in early March following a drill crew break and rig change currently in progress. Personnel shortages due to COVID are impacting Major Drilling's ability to provide relief drillers when project dedicated drilling crews are due for breaks. This is resulting
in drilling operating on a '20 days on - 10 days off' roster throughout the remainder of the Detroit programme. For
