ASX ANNOUNCEMENT 9 June 2021

Alderan’s Induced Polarisation Geophysics Confirms Potential for Multiple Copper and Gold Targets at Detroit

HIGHLIGHTS

  • Alderan’s induced polarisation geophysics at Detroit highlights multiple copper and gold targets.

  • It strongly supports Alderan’s earlier magnetics and highly anomalous rock samples.

  • IP and magnetic modelling of the Basin Complex highlights potential for a ‘classic’ porphyry system.

  • Three additional chargeability anomalies identified – Copperhead, Northern Extension and Southern Anomaly.

  • Soil sampling completed and assaying underway.

Alderan Resources Limited (ASX:AL8) ( Alderan or the Company ) is pleased to announce the results from an induced polarisation ( IP ) geophysical survey completed over the central portion of its Detroit Project, located in the Drum Mountains region of western Utah, USA. The survey strongly supports the previously released[1] ground magnetic results and enhances the potential of the area to host multiple gold and copper deposits.

Alderan has a consolidated exploration area at Detroit covering 24.7km[2] through a series of option agreements with tenement owners[2] . This provides the Company with the opportunity to conduct the first ever modern exploration over the entire mining district. Following consolidation, Alderan compiled past exploration data and completed stream sediment and rock sampling plus ground magnetics. This followed its earlier drill program of seven holes at the Mizpah prospect[3] . The results highlight potential for significant copper and gold mineralisation.

ASX ANNOUNCEMENT 9 June 2021

Commenting on the results, Alderan Managing Director Scott Caithness said:

“Alderan’s IP geophysics at Detroit strongly supports the earlier ground magnetics and rock sampling at the Basin Complex and has highlighted three additional IP targets. In particular, the results at the Basin Complex reinforce our view that the project has excellent potential for a buried copper, gold and molybdenum rich porphyry deposit due to its classic IP and magnetic signatures and associated geochemistry. All work done to date also suggests potential for additional copper and gold deposits related to intrusives, structures and stratigraphy peripheral to the Basin Complex.”

“Portable XRF analysis of soil samples is underway which will assist in defining and prioritising targets ahead of drill testing during the third quarter.”

Detroit Induced Polarisation (IP) Survey

Alderan completed an induced polarization geophysical survey over the central portion of the Detroit project area. The survey objective was to identify electrically chargeable and conductive bodies potentially caused by copper and gold mineralisation and altered host rocks. It was designed to cover the prospective area, including the Basin Complex and Copperhead prospects, identified from the ground magnetic survey completed in early May. The survey area and ground magnetics is shown in Figure 2.

Contractor SJ Geophysics acquired a total of 29.2 line kilometers of Volterra 2-D distributed dipole-dipole array chargeability and resistivity data on 11 parallel lines spaced 200m apart and oriented N60E. Each line consists of 2,000m of receiver dipoles (d=100m) and incorporates three additional current injection dipoles beyond each line ends for added sensitivity at the edge of the survey. The data was provided to Bolin Geophysical Services for processing and 3-D IP inversion modelling using the RES3DINV software.

Discussion of Results

Basin Complex

The chargeability and resistivity inversion models for the Basin Complex are consistent with a porphyry intrusive complex and strongly support the magnetic susceptibility model (Figure 1). The highest chargeability responses occur in an arcuate magnetic low surrounding the central Basin Main magnetic high. This is interpreted to be a halo of pyrite rich, magnetite destructive phyllic alteration extending outward from a potassic altered core containing magnetite. Modelling indicates that the highly chargeable (>40msec) zone is mushroom shaped, approximately 1km in diameter near surface, and narrows to a diameter of approximately 200m at 700m below surface (Figure 3).

The Basin Main magnetic and chargeability anomalies sit within a broad resistivity low as seen in Figure 4. Electrically resistive unaltered sedimentary rocks occur on the eastern and western margins of the survey area.

Figure 5 shows the chargeability model at a series of increasing cutoffs that demonstrate the Basin Main magnetic anomaly is less chargeable than the non-magnetic arc which surrounds it. This suggests that the Basin Main magnetic anomaly may be associated with less chargeable but interconnected sulphide minerals such as copper rich chalcopyrite, chalcocite and bornite whereas the highly chargeable nonmagnetic arc surrounding it is due to disseminated pyrite in phyllic alteration.

The series highlights that the Basin Main magnetic anomaly is a less intense chargeability anomaly than its surrounding magnetic low suggesting that it may be caused by interconnected copper sulphides such as chalcopyrite, chalcocite and bornite.

Copperhead

A prominent chargeability anomaly (>40msec) lies approximately 300m to the south-southeast of the historical Copperhead mine and 200m to the south of the Copperhead magnetic anomaly highlighted by

ASX ANNOUNCEMENT 9 June 2021

Alderan’s recently completed ground magnetic survey. The anomaly has dimensions of approximately 200m north-south and 250m east-west. It occurs on the most northerly line in the IP survey.

Alderan’s exploration at Copperhead has now identified prominent magnetic and chargeability anomalies with associated high-grade gold and copper in rocks in and around this historical mine.

Northern Extension

The Northern Extension chargeability anomaly (>40msec) is a new target which extends for approximately 700m north of the Basin Complex. It is approximately 200m wide in its central portion and appears to be stratigraphically controlled along the contact zone between the highly prospective Tatow limestone member and the Pioche Formation. Alderan’s drill hole to the south, DD20M-006, which intersected 83m grading 0.41g/t gold from 36m downhole lies in this stratigraphic position. Two rock samples collected from an east-west trending jasperoid in the hanging wall of the anomaly assayed 0.55g/t and 1.22g/t gold.

Southern Anomaly

The Southern Anomaly (>40msec) is also a new target which lies approximately 1km south of the Basin Main anomaly and 500m east of the historical EPH mine. Its dimensions are 500m north-south and 300m east-west at the >40msec cutoff used for anomaly identification. It is a large intense chargeability anomaly which is still clearly evident in the inversion model at the higher >60msec cutoff. The anomaly sits within the favourable Wheeler Shale unit which contains historic gold and copper mines developed on jasperoids along ENE faults.

Next Steps

Grid soil sampling every 50m along lines 200m apart has been completed over the prospective stratigraphy and intrusives at Detroit with sample preparation for analysis underway. A total of 2,200 samples were collected. Assaying will initially be done using a portable XRF before samples are sent to a laboratory for final analysis. The soil assays will assist in prioritising drill targets.

The IP grid will be extended to the north and south to close off anomalies identified at Copperhead and Mizpah. One additional line will be acquired to the north of existing coverage at Copperhead and two additional lines to the south will provide context to the Mizpah occurrence where anomalous chargeability appears to follow favorable stratigraphy which is open to the south.

Alderan has locked in a diamond rig to commence drilling in September. Final hole locations will be determined following receipt of soil sample assays and integration of all geochemistry, geophysics and geology data.

Detroit Project

The Detroit Project is one of four projects held by Alderan (Figure 7) in the state of Utah, USA. It lies within the Detroit Mining District, approximately 175km southwest of Salt Lake City, and contains numerous historical copper, gold and manganese mines. The district has been explored for copper and gold in the past by major mining companies such as Anaconda Copper, Kennecott, Newmont, BHP and Freeport-McMoRan but no one company was able to build a significant contiguous land position to enable district-wide modern exploration. The United States Geological Survey ( USGS ) has also explored the area, sampling extensive mineralised jasperoids.

Acknowledgment and appraisal of
exploration by other parties.
The Drum Mountains of west central Utah have long been a subject of mining and exploration for gold, copper, and
manganese, starting from 1800’s and continued until early 1900’s. This was followed by renewed interest in beryllium,
gold, manganese, and uranium in the past 20 years.

14

Gold and copper were discovered in the Drum Mountains in 1872, and from 1904 to 1917, gold, silver, and copper
was produced from siliceous replacement fissure deposits in jasperoids, limestone and dolomite, for a total value of
about $46,000.
Exploration for gold and base metals intermittently continued through the entire 20’s century. In particular, since early
1960’s, when jasperoids similar to that commonly found in highly productive gold mining districts have been identified
in the Drum Mountains of Utah, the specialised studies of the jasperoids have been undertaken by USGS and the
different mining companies. Sampling of these rocks commonly reveals anomalous concentrations of gold.
Geology Deposit type, geological setting and
style of mineralisation.
The focus of Alderan’s exploration efforts at Detroit is to discover a Carlin-like gold deposit. Key feature of Carlin-like
deposits include:
a)
Favourable permeable reactive rocks (silty limestones and limey siltstones)
b)
Favourable structures often coincident with mineral-related intrusive
c)
Gold-bearing hydrothermal solutions
d)
Micron-sized gold in fine-grained disseminated pyrite
e)
Common geochemical indicators As, Sb, Ba, Te, Se, Hg
f)
Common argillization and jasperoids; fairly common decalcification.

  • Acquired field data has been further processed using Geosoft Oasis Montaj software. The post-processing has included the following steps: 1. Georeferenced electrodes. 2. Identify and correct reversed polarity readings.

  • 3. Create new windowed IP channel: 414-1950 ms (Volterra ch. 11-26).

  • 4. Inspect and mask individual decays as necessary, especially at long offset.

  • 5. Recalculate apparent resistivity as verification step.

  • 6. Inspect chargeability/resistivity results for line-to-line consistency.

  • 7. Write formatted input files (ASCII) for inversion.

  • 8. Invert with RES3DINV software algorithm by M.H. Loke.

The soils further work (e.g. tests for lateral are collected every 50m on 200m spaced east-west lines. The results of this work are expected to refine individual extensions or depth extensions or prospect areas and optimise drill target selection with drilling planned to commence in the third quarter of 2021. large-scale step-out drilling).

The IP grid will be extended to the north and south to close off anomalies identified at Copperhead and including the main geological Mizpah. One additional line will be acquired to the north of existing coverage at Copperhead and two additional lines interpretations and future drilling to the south will provide context to the Mizpah occurrence where anomalous chargeability appears to follow favorable areas, provided this information is stratigraphy which is open to the south. not commercially sensitive.
