ASX Announcement

WOOMERA MINING IDENTIFIES PRIORITY LITHIUM DRILL TARGETS ACROSS PILGANGOORA LITHIUM ANOMALIES

Highlights

• Soil sampling program highlights six areas of significantly anomalous lithium identified as Priority 1 RC drill targets.

• Geological mapping recorded hundreds of pegmatite bodies either in low relief outcrops or more typically as mineral scatters.

• Infill soil sampling on a nominal 100m x 100m grid and 100m x 200m grid and rock chip sampling commenced on 20th February 2019 over areas of anomalous lithiumcaesium-tantalum identified from the Stage 1 sampling. The Stage 2 program was completed on 2nd March 2019.

• Rock chip sampling and soil geochemistry indicate the Project Area contains evolved pegmatites within supportive mineralised settings (metasomatic conditions) for lithium-caesium-tantalum pegmatites.

• Sufficient combined sampling results to constitute anomalous to strongly anomalous values for the Project area.

• The soil programs demonstrated near or above average levels related to lithium-hosted pegmatites - potential to locate economic mineralisation.

• Native Heritage Clearance awaited ahead of drilling program planning.

Pilgangoora Stage 1 Sampling Program

Woomera Mining Ltd (“WML”, or “The Company”) has previously reported the completion of a reconnaissance rock chip and gridded soil sampling program conducted in November 2018 over the Company’s Pilgangoora Project Area covering E 45/4790 and E 45/4796.

The Project is located on 100% owned tenements approximately 100km south east of Port Hedland - the Pilgangoora region is known as one of the world’s richest pegmatite-hosted lithium provinces. Rock chips and gridded 400m x 400m soil sampling demonstrated that the area contained evolved pegmatites carrying anomalous lithium, caesium and tantalum.

Geological mapping recorded numerous pegmatites of variable widths and lengths occurring within the Project Area. Several dozen pegmatites were observed and it is likely that many more are present given the limited outcrop in the areas mapped and sampled.

The board and management of Woomera Mining were encouraged by the results of the Stage 1 exploration program.

The results suggested the Project Area to be prospective for lithium-caesium-tantalum pegmatites, more complex petalite-lepidolite-elbaite-amblygonite pegmatites and also for rare earth allanite-monazite pegmatites.

A second more comprehensive soil sampling and rock chip program was completed between 20 February and 3 March 2019 and the results reported herein.

Stage 2 Sampling Program

A total of 588 soil samples were collected on nominal 100m x 100m and 100m x 200m grid over areas of lithium anomalism identified during the Stage 1 sampling program.

In addition to the soil sampling, 64 rock chip samples were taken across E 45/4790 and E 45/4796. Sampling was undertaken on numerous pegmatite mineral scatters, on rarer pegmatite outcrops and over a 3km x 2.5 km area in central mid E 45/4790 consisting of greisenised granite.

A total of 739 soil samples were collected during the Stage 1 and Stage 2 programs. Analytical results show:

• 322 samples greater than the weighted average value of 25.9ppm lithium

• 29 samples highly anomalous for lithium assaying above 47.4 ppm, with a peak value of 82.4ppm

• Niobium up to 125ppm

• Caesium up to 40.4ppm

• Tantalum up to 43ppm

In addition to the soil samples, a total of 96 rock samples were collected from 2 sampling programs. Analytical results show:

• 17 samples above 100ppm lithium, with a peak value of 280ppm

• Beryllium up to 1910ppm

• Niobium up to 80ppm

• Caesium up to 62.4ppm

• Tin up to 25ppm

• Tantalum up to 20.6ppm

• Phospherous up to 2,400ppm

• Rubidium up to 1,155ppm

• Total peak values of rare earth elements up to 286ppm

The results demonstrate that several areas are highly anomalous for lithium bearing pegmatites and these areas will be the focus of RC drilling.

Field Program 2 Rock and Soil Sampling Program

Rock chip sampling was undertaken on numerous scattered pegmatites, and rare outcropping pegmatite. A 3km x 2.5 km area in central-mid E 45/4790 consists of greisenised granite with a core area covering 2km x 1.5km of intense greisenisation (Figure 1 and Plates 1 & 2).

Plate 2. Petrographic sample MRR02-040. Samples contains 280ppm lithium and 58ppm caesium. Strongly greisen-altered, coarse grained leucocratic granodiorite. The rock originally consisted of interlocking grains of quartz, sodic plagioclase and minor microcline, with a few small grains of biotite, and traces of zircon, apatite and a FeTi oxide phase. Imposition of pervasive hydrothermal alteration led to considerable replacement of feldspars by fine through to coarse grained muscovite, with a little epidote and trace chlorite. Similarly, biotite is also locally replaced by muscovite, chlorite and epidote.

The number of soil samples for the combined programs is statistically significant to inform the setting for thresholds for what constitutes anomalous to strongly anomalous values for the Project.

Figure 2. Lithium map produced for E45/4790 and E45/4796 from field data collected from work programs 1&2. Anomalous areas are also displayed with magenta representing the most anomalous areas.

.

Broad lithium anomalism is exhibited in the north, south and eastern margins of E45/4790 at Areas K, I, D, and H. Zones of lithium anomalism are also observed centrally at Areas M and F.

Many soil samples were coincident with silcrete and drift which may understate/mask the underlying geochemistry and it significance for LCT pegmatites.

There is large lower than average lithium evident in central E45/4790 which is believed to be coincident with a buried granite dome.

EL 45/4790 host a large oval-shaped area (3.5km x 2.5km) of greisen with a core of 2km x 1.5km of intense greisenisation. In the greisen, pervasive hydrothermal alteration has led to considerable replacement of feldspars by fine through to coarse grained muscovite, lesser epidote and trace chlorite and garnet. Biotite is also locally replaced by muscovite, chlorite and epidote.

The greisen area host numerous flat lying and high angle pegmatite and zeolite veins. Further mapping and sampling will be undertaken to better understand the greisen’s influence on lithium mineralisation.

Results from sampling during Stage 1 on E45/4796 indicated limited anomalism however, the soils samples taken during Stage 2 reinforced that the tenement is prospective for lithium. The results relating to E45/4796 might understate the potential for broad LCT anomalism on this tenement.

Generally, rock samples support soil assay results. Area D is the exception which is dominated by outcropping low relief silcrete which was low in lithium.

In Figure 2, broad moderately strong to very strong caesium anomalism is observed in the general periphery of E45/4790. Area H is especially anomalous where the caesium is related to a series of parallel pegmatite dykes approximately 40m in width. Anomalous caesium occurs in Areas I, D, M, F, and K. Magenta represents to the most anomalous areas.

Unlike the previous two figures, the most anomalous areas of niobium (Figure 4) are constrained to the eastern periphery of E45/4970 (Area D). More localised individually high soil results are evident in the other areas.

Discussion

The Project area contains many hundreds of pegmatites in outcrop ranging from 10cm, up to many tens of metres similar to that Area I (Plate 3). Evidence of very weathered pegmatites proliferate many areas as demonstrated in Plate 4.

It is generally accepted that LCT pegmatites within the Pilbara only occur in the greenstone tectonic margins of the cratons’ granitic domes. However the data produced from the recent field programs demonstrate the potential for lithium-rich pegmatites within the Pilbara intracratonic granitic domes, if not at least the Carlindi Granite.

It can be expected that the contribution from elements of interest related to LCT pegmatites are extremely low from the host Carlindi granite, as the minerals of interest are incompatible with granite crystallisation. Thus element baselines produced from statistical analysis are not influenced by the granitic rocks. Elements used in the studies produced above can only be sourced from LCT pegmatites, namely Ga, Be, Cs, Nb and Li have no low-level contribution from the Carlindi granite.

Recent studies on relative abundance of these elements are shown below in Table 1.

	WML soil programs	WML soil programs		WML rock samples	Crustal abundance (Zhaochu & Goa, 2008)
Element	average (ppm)	1 std. dev. (ppm)	Peak value (ppm)	Peak value (ppm)	Average (ppm)
Be	2.1	17.4	417	1910	1.9
Cs	7.7	10.2	40.4	62.4	4.9
Ga	13.3	15.6	21.6	62	18.6
Li	25.9	35.6	82.8	280	41
Nb	8.6	15.5	125	80	11.6

Table 1. Comparative analysis of WML combined soil analysis with relative crustal abundance (Zhaochu & Goa, 2008).

Table 1 demonstrates that near or above average elemental values related to LCT pegmatites exist in the Project area, peak values well exceed global relative crustal abundance. The opportunity to locate economic mineralisation is considered to be good.

Lithium values for soil results exceeding 47.7ppm, or the upper statistical range number a total of 29 samples, with the peak value of 82.8ppm strongly indicate that lithium is the primary element of exploration interest, while REE’s remain relatively low at a peak combined value of 286ppm.

==> picture [343 x 197] intentionally omitted <==

The significance of the results stated above are illustrated in Figure 5. Peak values of all elements related to fertile rare metal pegmatites are evident above crustal averages.

Generally, pervasive elements of no economic consequence associated with LCT pegmatites are present, with phosphorous at a peak value of 2,400ppm and rubidium at a peak value of 1,155ppm.

Priority Drill Targets

Six areas (some containing multiple targets) have been identified from a combination of Stage 1 And Stage 2 soil and rock chip sampling (see Table 2 below).

Area	Length (minimum) m	Width (maximum) m	Comment
D	900	80	Potentially proximal parallel mineralised features
F	800	60	Another feature 800m long may also overlap
H	480	50	Shape maybe truncated, and differing individual pegmatites
	300	40	Southern shape
I	500	40	Well supported by other elements, Nb, Be, and Cs
	120	30	Smaller target
	170	40	Strong overlap of anomalies
	150	30	Smaller target
K	500	60	Sub-parallel to a Cs anomaly
M	700	50	Several parallel features may cluster either side

Many overlapping or converging regions of strongly anomalous mineralisation are either directly or indirectly related to LCT pegmatites and are observable in Area D (Figure 6). The orientation of lithium (white dashed line) is well supported by the other local coincidental elements of gallium, niobium, and beryllium.

A general north-west to south-east corridor is evident which is approximately 100m in width and up to 800m in length. The potential for a southern extension is untested.

The data supports converging structural orientations as noted in secondary south-west corridors whose southwestern extension remains untested.

Priority Drill Target - Area F

==> picture [497 x 352] intentionally omitted <==

Figure 7. E45/4790 Area F lithium anomaly map. Outlines for gallium (Ga), niobium (Nb), Caesium (Cs), lithium (Li), and beryllium (Be) are also displayed. Untested areas shown in yellow hash ellipses. Combined programs 1&2.

A single less than 100m wide, 700m long lithium anomaly is identified at Area F (Figure 7). A more north westerly trending anomaly may exist based on the linear trend between beryllium, niobium, caesium and to a lesser extent lithium, occurring north-west of the identified lithium anomaly.

11

Priority Drill Target – Area H

==> picture [497 x 351] intentionally omitted <==

Figure 8. E45/4790 Area H lithium anomaly map. Outlines for gallium (Ga), niobium (Nb), Caesium (Cs), lithium (Li), and beryllium (Be) are also displayed. Untested areas shown in yellow hash ellipses. Combined programs 1&2. The area of magenta extending south of the tenement boundary is an artifact of interpolation projection produced from the GIS software.

Drill target consists of a main 480m x 50m north-westerly trending highly anomalous LCT zone and a secondary parallel zone 200 metres to the south (Figure 8). Pegmatite mineral scatters abound in the areas of anomalism.

12

Priority Drill Target – Area I

Two highly anomalous trends occur in Area I (Figure 9). These anomalies are unconstrained and remain untested to the west and south. Opportunity may exist for larger endowment where these two orientations converge.

13

Priority Drill Target – Area K

==> picture [497 x 357] intentionally omitted <==

The area K drill target consists of a 500m x 60m east-northeast trending lithium anomaly with a sub-parallel caesium anomaly.

14

Priority Drill Target – Area M

==> picture [497 x 353] intentionally omitted <==

Figure 9. E45/4790 Area M lithium anomaly map. Outlines for gallium (Ga), niobium (Nb), Caesium (Cs), lithium (Li), and beryllium (Be) are also displayed. Untested areas shown in yellow hash lines. Combined programs 1&2.

The area M drill target consists of a 700m x 50m northeasterly trending lithium anomaly defined by soil sampling.

Future Work Plan

E 45/4790 and E 45/4796 were granted without having signed Heritage Agreements in place. Woomera has consulted with the Njamal Aboriginal Corporation as it relates to the Njamal #1 Native Title Claim and has signed the Njamal Standard Heritage Agreement and is awaiting signing by the Njamal.

Woomera will lodge a Notice of Activity with the Njamal outling the upcoming proposed work consisting of access track construction and RC drilling seeking clearance for RC drilling. Such a Notice may trigger the need for Heritage Clearance. As such the commencement date for drilling cannot be determined at this time.
