Whilst testing of the Lower Antelope Shale continues, the results achieved to date have allowed the Company to determine the Recoverable Contingent Resource for the zones tested so far, as follows: Oil Gas Estimated Recoverable Contingent Resource (100%)* Formation Low (1C) MMbbls Best (2C) MMbbls High (3C) MMbbls Lower Antelope Shale 5 12 22 Lower Stevens “B”/Fruitvale 5 14 25 Total 10 26 47 Formation Low Bcf Best Bcf High Bcf Lower Stevens “B” 8 22 44 These Contingent Resource figures do not take into account shallower potential pay zones that are yet to be tested. Testing of these zones may result in additional Contingent Resources. A detailed summary of the Paloma project and results achieved to date is attached to this announcement. Following the encouraging results from Paloma Deep-1 (PD-1), Neon commenced drilling Paloma Deep-2 (PD-2), an appraisal well designed to confirm the reservoir characteristics and areal extent of productive zones encountered in PD-1. Additionally a shallow exploration well was spudded on the western portion of the leased acreage, targeting shallow zones that could not be tested in the PD-1 or PD-2 wells. All three wells are targeting reservoirs that have produced hydrocarbons either on the Paloma structure itself, or nearby within the prolific San Joaquin Basin. The status of the three wells is as follows: 3 Paloma Deep-1: Testing of the Fruitvale and Lower Stevens “B” confirmed the presence of producible gas and light oil/condensate. Maximum unassisted flow rates of 1.9 MMcfd gas and 226 bpd of oil/condensate were achieved before flow abruptly ceased as a consequence of plugging of the testing tools by packer debris, brought on by formation damage caused by testing. The Lower Antelope unconventional shale is currently testing with pump-assisted rates ranging from 20 to 200 barrels of fluid per day, and oil cut ranging from 10% to 20%. It is intended that testing will continue until sufficient data is gathered to fully understand the commercial potential of the zone. Additional shallower zones of interest still remain to be tested in the well, including the Paloma Sandstones and the Upper Antelope Formation. Paloma Deep-2: Intermediate casing has been set at 10,128 feet, and at time of writing the well is drilling on schedule. Paloma-3: This low cost well has reached TD of 6,000 feet and has been completed for production testing of thin gas sands within the Etchegoin Sandstone Formation. A “workover” rig is to be installed at the wellsite prior to testing, with results expected within the next two weeks. Paloma area schematic cross-section showing relative location of wells 4 In the event that the appraisal programme is successful in proving commerciality, resource certification will quickly follow and development of the field is expected to commence shortly thereafter. Neon anticipates that both the Lower Stevens “B” sandstone reservoir and the unconventional Lower Antelope and Fruitvale Shales would be developed using high angle wellbores designed to optimise connectivity to the relatively low permeability reservoirs, thereby maximising rates of production and hydrocarbon recovery per well. The extensive infrastructure in the area will facilitate efficient monetisation of the asset. *Contingent Resource estimates for Paloma Deep have been generated internally by Neon in compliance with the SPE 2007 Petroleum Resource Management System (PRMS), under the supervision of David Cliff, Exploration Manager, a qualified Petroleum Geologist with 31 years experience in the oil exploration industry. Mr Cliff is a member of the Petroleum Exploration Society of Australia and of the American Association of Petroleum Geologists, and has consented to the inclusion of the technical assessment in this announcment. _________________________________________________________________________ Enquiries: Managing Director: Ken Charsinsky Chief Financial Officer: Ben Newton Telephone: 08 94811176 Website: www.neonenergy.com Neon Energy Ltd, ABN: 49 002 796 974, Ground Floor, 88 Colin Street, West Perth,6005 Ph: +61 (08) 9481 1176 Fax: +61 (08) 9481 7720 PO Box 1789, West Perth, 6872 Website: www.neonenergy.com E-mail: info@neonenergy.com 5 Paloma Project Overview Paloma Deep Play Concept The Paloma Deep play concept was to test the Stevens Sands, Antelope Shale and Fruitvale Shale within the Monterey Formation, at the northwestern end of the field where these zones had not been previously produced; despite having been proven productive in the southeastern portion of the field and elsewhere in the San Joaquin Basin. Analysis of the 3D seismic amplitude response in the Stevens Sands highlighted the potential for development of a permeable reservoir at the north-western end of the field. While drilling, the Paloma Deep well would also test for bypassed pay zones in the previously produced shallow zones of the Etchegoin and San Joaquin Formations, and the Paloma Sands. Deep gas in the Round Mountain siltstones, indicated by a strong seismic anomaly, was also originally an objective and remains a target for future drilling. Schematic cross-section showing Paloma Deep play concept Paloma Deep-1 Results In late 2011, the PD-1 well reached TD at 13,320 feet, some 310 feet into the Fruitvale Shale. Analysis of wireline logging data confirmed the presence of oil and/or gas/condensate in eight zones including three unconventional oil shale zones (with two additional zones, in the Paloma Sand section, interpreted to be depleted). In aggregate these zones represent approximately 1,000 net feet of potential hydrocarbon pay. The Fruitvale Shale exhibits characteristics of a producing oil shale and is interpreted to be approximately 1,300 feet thick at the well location. PD-1 penetrated 310 feet of the formation at TD. Two production tests of the Fruitvale Formation recovered oil and gas although it is thought that some of this production was coming from the Lower Stevens B sand, bypassing leaking completion packers. The most notable zone of interest was encountered in the Lower Stevens “B” sand, within which a gross column of 230 feet of continuous potential hydrocarbon pay is interpreted with a reservoir net to gross ratio of 81%. This pay zone flowed oil and gas on test and because it 6 extends over at least 730 acres of Neon’s 2,847 gross acre lease holdings, it represents a potentially significant resource to the Company. The Lower Antelope Shale is characterised by a favourable combination of being a naturally fractured siliceous shale (chert) and a mature source rock that is presently generating oil within the Paloma area. The 508 foot section encountered in the PD-1 well has proven to be a prime candidate for unconventional oil production. A 34 foot sand within this interval, above the current test zone, produced one of the most positive oil shows encountered in the well, and it will be tested after the current test of the Lower Antelope is completed. As a resource play extending across the entire 2,847 gross acres of Neon’s current lease, the Lower Antelope Shale is potentially a very significant resource. Schematic cross-section showing Paloma Deep-1 results Neon also plans to test the uppermost Paloma Sand in PD-1, which is interpreted to be oil bearing. The sand sits within the Upper Antelope Shale, which is also interpreted to be a good candidate for unconventional oil production as it already produces elsewhere in the field. This 155 foot (gross) shale oil zone will also be tested in due course. 7 The upper part of the Lower Stevens ”A”, the Western Flank Sand and the Middle Stevens are interpreted to contain sub-economic pay due to the poor quality of the reservoir and high residual water saturations. The poor potential of the Lower Stevens “A” sand was confirmed by testing; producing water and only a small quantity of gas. These zones will however be reassessed in Paloma Deep-2, possibly with better results due to the updip location relative to PD-1. Production Testing Summary Four of the zones of interest have been tested thus far, via seven production tests. In order to obtain commercial production rates from an unconventional (low permeability) reservoir effective connection via a natural or man-made fracture system is necessary. Determination of reservoir characteristics and the potential efficacy of various well stimulation techniques in these oil reservoirs requires the integration of wireline log data with pressure transient data obtained during long-term production tests, which are currently ongoing. Testing of the Fruitvale and Lower Stevens formations has confirmed the presence of producible gas and light oil/condensate. Test 1, of the Fruitvale Formation, flowed to the surface unassisted at a maximum rate of 1.9 MMcfd and 226 bpd of oil/condensate (oil gravity measured at 40° °API). It is believed that the flow is partially attributable to the Lower Stevens sandstone, bypassing a defective “swellable packer”. After flowing for 23 hours the flow ceased abruptly and the testing tools were found to be plugged with packer debris. The second test, of the Lower Stevens Formation, was stimulated with nitrogen and produced a maximum flow at surface of 343 Mcfd (thousand cubic feet per day) gas. The tool was subsequently found to be plugged with sand, and sand fill was found below the test tool. It is believed that sand and silt collapsed around the outside of the casing and formed a permeability barrier in the annulus of the borehole (as in the test tool) thereby inhibiting flow. This was confirmed by similar results in Test-3, in which more perforations were added in the Lower Stevens interval; and Test-4 in the Fruitvale and Lower Stevens intervals combined, which resulted in the similar gas flow rates and oil recoveries. Neon believes that the test performance was severely inhibited due to a compromised “swellable packer” completion, and to sanding issues resulting from geomechanical stresses that exceeded the formation strength of the local sandstone facies. These issues can be overcome in future well completions now that the operational challenges are better understood, and the PD-2 well and completion has been designed to mitigate the problems. 8 Flaring gas on test at Paloma Deep-1 Test-5, in the Lower Stevens “A” sand, produced water into the well bore with only a small amount of gas. This zone is therefore deemed to be non-commercial. Test-6 was conducted in the lower two thirds of the Lower Antelope Shale opposite naturally fractured shale and chert beds. It was a highly successful test in that it established that oil can be swabbed (pumped) out of the Antelope Shale prior to stimulation, and improvements in flow rate were recorded after an acid wash; which was performed in order to remove plugging solids from reservoir pores in the wellbore. Test-7 added more perforations to the previous test zone and a larger acid stimulation job was conducted. A jet pump was installed to produce back the acid load volumes and to conduct a long-term production test. Although the well has not yet fully “cleaned up” oil production from the zone has been proven, with pump-assisted rates ranging from 20 to 200 barrels of fluid per day and oil percentages ranging from 10% to 20%. Oil gravity is measured at 28° °API to 30° °API, and it is anticipated that with continued pumping the test may clean up further, with an associated increase in oil cut. Neon intends to use the test data from this zone to establish the magnitude of the potential resource and the optimal completion strategy at this time. High angle or horizontal wells, intersecting more reservoir fractures, are expected to be the basis of any future development. Future testing will include the sandy upper zone of the Lower Antelope Shale, the Paloma Sands and the Upper Antelope shale. 9 Paloma Deep-2 PD-2 was spudded on 9th May 2012 as an appraisal well to prove the flow potential of the Lower Stevens and Fruitvale formations, using a standard cemented liner completion as opposed to the “swellable packer” completion adopted in PD-1. Reservoir coring of the Lower Antelope Shale, the Lower Stevens and the Fruitvale Shale will help determine the reservoir and sourcing parameters of each formation, so that wireline log responses can be calibrated and resource estimates updated. The well is targeting a zone of high seismic amplitude at the Lower Stevens “B” level, which is expected to correlate to favourable reservoir parameters. The well should be completed for testing in 3 to 4 weeks time. Paloma-3 (B&N Minerals 81B-36) Neon drilled the Paloma-3 well during May 2012, to a TD of 6,000 feet. The objective of this well was to test zones that were impractical to test in, or not penetrated by, the PD-1 and PD-2 wells. After reaching TD several thin gas sands were identified by wireline log interpretation of the San Joaquin and Etchegoin formations, typical of sands that have produced in the area. Downhole pressure data indicates that some of these sands remain charged with gas, and Neon is currently preparing to production test during June 2012. Background Information The Paloma field was originally discovered in 1934 and commenced production shortly thereafter, principally from the Paloma Sandstone Formation. Initial development consisted of 150 oil wells and 45 gas wells, with a secondary phase in 1973 consisting of 23 additional wells targeting the Lower Stevens Formation in the southeastern portion of the field. Having produced in excess of 60 million barrels of oil and 432 billion cubic feet of gas the field ceased producing at significant rates some 25 years ago and today lies essentially abandoned, with only 80 bopd being produced from the Lower Stevens Formation in the southeast of the field. More recently the Upper Antelope Shale is being produced by a single well in the eastern part of the field. The opportunity at Paloma is provided by a combination of 3D seismic analysis, modern drilling/completion technologies and the recent recognition of the Monterey formation as a significant unconventional reservoir. Neon (Operator) and partner Solimar Energy (ASX: SGY) increased the Paloma Joint Venture’s acreage holding prior to drilling the PD-1 well by securing additional oil and gas leases to the east, bringing the total holding to 2,847 gross acres. Neon holds an 85% working interest in the original (western) leases, and a 75% working interest in the new (eastern) leases, with Solimar holding the balance of interest. 10 Paloma area schematic map showing location of wells and leases Aspects of Petroleum Geology The prospective intervals of the Paloma Field range in age from 15 million years to 1 million years (Middle Miocene to Pleistocene). During the Middle Miocene period the Paloma area was situated within a deep sea embayment of the Pacific Ocean, receiving pulses of sediment sourced from the uplifting Sierra Nevada mountains to the southeast. These periods were interspersed with quiet periods in which nutrient rich waters supported the formation of diatomites (micro-organisms with siliceous tests) that now form the prolific source and reservoir of the Monterey Formation. The Monterey Formation is a prolific source rock within the San Joaquin Basin, having generated the vast majority of oil found within the basin. Mature Monterey source rocks are currently gaining widespread industry recognition as a significant unconventional resource play, and Neon’s Paloma leases are optimally situated within the Monterey play fairway. 11 Paloma area stratigraphic column The petroleum potential at Paloma is not restricted to only the Monterey Formation however, as historically there are four hydrocarbon reservoirs that have been developed in the area: Etchegoin Formation sands (gas), Symons Formation (oil and gas), Paloma Sands (oil and gas), and Lower Stevens Formation (Oil and Gas). 1939 7.5Ma “Paloma Sands” Paloma Field Outline 1942 6.3Ma “Symons Sands” 1934 2-5Ma Shallow Gas sands – Etchegoin / San Joaquin Fm & a few 7.5Ma Paloma Sand oil wells 1973 8.2Ma “Lower Stevens Sands” 1959 2-5Ma Shallow Gas sands – Etchegoin / San Joaquin Fm Paloma Oil Field: Historic production by reservoir 12 Reservoir and production parameters of the four main reservoirs are summarised in the table below: Reservoir Ethchegoin Sand Symons Fm Paloma Sand Lower Stevens Approx.

The unconventional reservoirs such as the Lower Antelope are not constrained in this manner and potential therefore exists over the entirety of Neon’s acreage position. Summary Drilling and testing of the Paloma Deep prospect has confirmed the existence of producible oil, condensate and gas in the Lower Stevens, Fruitvale Shale and Lower Antelope Shale within Neon’s Paloma acreage. Additional potential exists for hydrocarbons to flow from the Etchegoin/San Joaquin gas sands, the upper Antelope oil shale, and the Paloma oil sands; all of which have yet to be tested. Neon is greatly encouraged by the project’s upgraded potential for commerciality, as evidenced by the decision to proceed immediately with the drilling of the Paloma Deep-2 and Paloma-3 wells. The new information acquired during ongoing testing of the Paloma Deep-1 well will serve to refine the resource assessment model for the Lower Antelope Shale, while Paloma Deep-2 will test the areal extent of the resource and acquire reservoir cores in order to better understand reservoir character and thus the potential for commerciality. Results achieved to date are consistent with Neon’s pre-drill estimate of the resource potential of the project, and in the event of appraisal success Neon will commission a third party expert to certify “P1” reserves for the conventional zones and to provide an independent Contingent Resource estimate for the unconventional zones as a precursor to development. The Company looks forward to providing further updates as key milestones are reached. 13
