Highlights
• Infill soil sampling defines large scale gold anomaly at Maggie Hays Hill
• Gold results from 15-85ppb
•700 metres long and up to 170 metres wide
• Drilling and heritage survey update
Intra Energy Corporation Limited (ASX: IEC) (“IEC” or the “Company”) is pleased to
announce that new soil sampling assays have defined a high tenor and large-scale gold
anomaly at the Maggie Hays Hill project.
Managing Director Ben Dunn commented: “We are rapidly advancing the Maggie Hays Hill project to drilling. The new soil results have defined a strong gold anomaly along a mineralised trend that extends another kilometre to the north. Coupled with the recent assay results from the central gold zone that confirmed historical trenching and drilling results (i.e. 2 metres at 11 g/t gold) we believe there is great potential for a gold discovery. The tenement also has multiple other anomalous gold targets generated from the recent soil sampling program that require follow up”.
“IEC has also identified additional lithium anomalism with rock chip sampling at the southern end of the tenement identifying outcropping pegmatites with beryl crystals and elevated lithium, niobium, tantalum, caesium and tin. Lithium drill targets have now been defined along a 2.5-kilometre zone and we are very keen to get these drilled”.
“Preparation is underway for a 2000 metre RC drill program to test both the gold and lithium targets. A heritage survey scheduled for late May was slightly delayed due to heavy rain and will now occur this month. IEC expects to be able to drill in mid-July”.
High tenor, large scale gold anomaly defined by soil geochemistry
In fill soil sampling conducted in May has defined a large scale 700 metre long and 100- 170-metre-wide gold anomaly with gold value between 15 and 85ppb (Figure 1, Table 1). The sampling was conducted to follow up a broad +1.5km long gold anomaly that occurs along the sheared contact between a basalt and ultramafic unit. Field mapping identified quartz reefs occupying dilational jogs along the shear zone and these are strongly correlated with the elevated gold results. The company is planning to test this target in the upcoming drill program.
Elsewhere in the tenement (Figure 2), multiple point soil anomalies with elevated gold results >20ppb require further investigation. Most anomalies are associated with contacts between mafic and ultramafic units. Quartz outcrops are common along dilational jogs in the contacts and further exploration will focus on areas where structural flexures generate larger dilational zones. Near the central gold zone there are multiple gold anomalies associated with contacts that extend over several hundred metres.
Additional Lithium Anomalism
During May, additional mapping and rock sampling at the southern end of the tenement to assist drill hole planning identified several pegmatite outcrops that appear to dip shallowly to the west. Samples collected display elevated lithium, tantalum, niobium and caesium (Table 2). One sample contained 90ppm Lithium, 220ppm Niobium, 65ppm Tantalum and 32 ppm Caesium and the rock specimen contained beryl crystals. Drilling has been planned for this target.
Heritage and drill program preparation
The Maggie Hays Hill (MHH) heritage survey has been rescheduled to mid-June due to heavy rain that closed the Norseman-Hyden Road on the 30th of May restricting access to the project for the survey team. Due to other heritage survey commitments, the survey could not be rebooked until the week commencing June 17th.
The Company expects the survey to be completed over 4 days and the results to be available within three weeks. Thereafter, the company can undertake track and drill pad preparation and commence drilling in mid-July.
Maggie Hays Hill Project Background
The Maggie Hays Hill (MHH) project (80%) is adjacent to the Norseman-Hyden Road and the Maggie Hays and Emily Anne nickel mines (Poseidon Nickel Limited) and camp at Windy Hill. The project is accessible via well-formed tracks, particularly at the southern end. The geology consists of NNW trending extensively faulted mafic and ultramafic rocks bounded by younger granitic rocks to the west and east. The project is prospective for lithium, nickel, and gold.
The project is 25 kilometres north of two separate spodumene lithium discoveries at Burmeister Hill (TG Metals) and Lake Medcalf (Charger Metals) (Figure 3). There are also lithium mica (lepidolite) pegmatites at Mt Day 10 kilometres North of the MHH project. Recently, Rio Tinto has farmed into the Charger Metals tenements in the region, and in a related transaction, Charger Metals has acquired all of Lithium Australia’s interests in their joint venture tenements.
Lithium spodumene targets include a series of pegmatite dykes outcropping along a 2.5- kilometre north-northwest trend. Geological mapping indicates that the dykes all occur adjacent to an amphibolite ultramafic unit which can be traced for 7 kilometres across the tenement. Soil sampling geochemistry conducted in 2021 identified lithium anomalism adjacent to the 2-kilometre pegmatite trend and for a further 2.5 kilometres north of the outcropping pegmatites (I.E, along a 5-kilometre trend).
There is also potential for pegmatites to the east and north. A key element of the lithium prospectivity is the presence of spodumene and lepidolite in the same mafic rock sequence to the north and south of the tenement indicating that there are multiple LCT fertile granitoids in the area.
