ASX ANNOUNCEMENT ACN 123 567 073 27 June 2014
CONDUCTOR DETECTED BY GROUND EM SURVEY AT PLATO PROSPECT IN FRASER RANGE
_______________
-
Fixed loop electromagnetic (FLEM) survey over Plato identifies deep conductor, open to the south – possible feeder sill or conduit
-
ENT secures $1.2 million for follow up FLEM and drilling at Fraser Range
-
Including Plato, 7 high priority targets outlined for FLEM surveys
-
Assays received for Plato diamond drill core - PLRCD001, 003 & 006
Enterprise Metals Limited (“Enterprise”; “the Company”, ASX: ENT) advises that it has received the results and interpretation of several fixed loop electromagnetic (FLEM) surveys over the Plato and Plato West prospects.
The FLEM survey over Plato has identified a deep conductor on the southern margin of Plato, which possibly relates to a feeder sill or conduit. This FLEM anomaly is open to the south and further FLEM surveying is required prior to drilling. The FLEM survey over Plato West detected no late time conductors.

– FLEM Survey Bedrock Conductor Identified
Vortex Geophysics has completed fixed loop electromagnetic surveys over the Plato and Plato West prospects for Enterprise. Due to access problems, the planned FLEM survey at Plato East was not completed.
Readings were taken at 100m station intervals on lines 200m apart for each loop (1,000m by 1,000m). Each station had a minimum of three repeat readings. A total of 25 lines (250 stations) were surveyed (22.5 line km). The data has been processed and interpreted by an extern consultant. The locations of the fixed loops and reading stations are shown below in Figure 2.

Commentary on FLEM Survey
A late time bedrock conductor was observed at the southern end of Plato. The feature appears to have a different orientation to the Plato body and could represent a potential feeder sill or conduit.
Modelling of this data indicates the source has not been fully covered by the current survey. Additional surveys to the south are required to better define this feature. Additional surveys to the east and west of Plato are required to target potential vertical mineralization associated with the margin of the olivine-rich gabbro-norite. It was recommended that addition FLEM be undertaken prior to further drilling at Plato. No bedrock conductors were observed in the immediate vicinity of the RC/Diamond drilling.

No conductors were identified over the limited strike of the survey over Plato West. However, it was recommended that shallow drilling of Plato West be undertaken as a low priority to follow up anomalous soil geochemistry responses.
All of the area in coloured blue in Figure 1 is below 0.2pT/A in amplitude and is effectively the noise level of the FLEM system.
Preliminary Assays from Diamond Drill Core – Elevated Nickel-Copper
Preliminary laboratory assays have been received for diamond core “tails” of holes PLRC001, 003 and 006.
Hole PLRCD001 displayed 2 narrow half-metre intervals of +1,000pmm nickel and elevated copper.
Hole PLRCD003 displayed 63m @ 1,360ppm Ni from 271m (bottom of RC hole) and a further 7m @ 1,490 ppm Ni and 334ppm Cu from 334m. These assays are consistent with the disseminated nickel and copper sulphides observed in the drill core. It should also be noted that the RC component of PLRC003 returned an interval of 62m @ 2,055ppm Ni from 208m to 270m. (Refer Figure 3)
Hole PLRDC006 displayed no nickel assays greater than 1,000ppm, which is consistent with the hole having drilled unmineralised gabbro-norite.
A summary of the diamond drill core assay results is shown in Table 1 below, and a summary of the mineralised RC sample results is shown in Table 2.

Revised Schematic Cross Section – Nickel-Copper Host Rocks
The Company has now combined the geological logging, assay results from RC chips and diamond core (DC) and petrological studies of drill chips to produce a revised schematic cross section. Refer Figure 3 below.
As previously reported, thin sections of five RC chip samples and polished mounts of nine RC chip samples from PLRC002 and PLRC003 displaying visible sulfides were examined petrographically by a consultant. It was concluded that the chip samples are all mafic granulites derived from norite, gabbronorite and olivine-bearing gabbronorite protoliths, and that these drill chip samples were originally cumulate mafic rocks in a layered mafic complex .
All fourteen observed samples carried sulphides that appear to be primary sulfides in terms of their mineralogy, with the typical assemblage being pyrrhotite with subordinate chalcopyrite and pentlandite.
The presence of magmatic sulphides in the Plato rocks suggests that further exploration should be directed at locating more primitive, relatively olivine-rich, feeder-type sills and conduit rocks, such as the picritic sills that host the giant Norils’k Ni-Cu deposit.

– Additional Targets Exploration Priorities
From analysis of the geology, geochemistry and geophysics of the Plato body, the Company concluded that the relatively olivine rich units (containing disseminated nickel and copper sulphides) of the gabbro-norite complex are essentially non-magnetic, while the host gabbro-norite is strongly magnetic. In addition, the olivine rich units are softer than the surrounding rocks and weather more readily (and more deeply) due to the sulphides combining with groundwater to form acidic conditions.
This conclusion has led to a re-appraisal of the Company’s low level detailed 100m line spaced airborne magnetic data, to identify magnetic lows which could represent feeder sills or conduits containing massive sulphides. This Company’s previous soil sampling results and HeliTEM data were also re-appraised.
The early channel HeliTEM data had identified areas of deeper weathering and/or palaeochannel development, which could signify acid leaching due to the presence of sulphides. This phenomena was observed at Plato (refer Figure 3) and has been well documented in the greenstone hosted gold deposits of the Eastern Goldfields. The Company has identified 7 targets (including Plato) which warrant further investigation via EM surveys and drilling. These targets are shown in Figure 4.

These targets are tabulated below in Table 3, and Figure 5 shows the location of palaeochannels and deep weathering as identified from the early channels of the Company’s HeliTEM survey. It should be noted that surface geochemistry was ineffective at Plato East and Oceanus due to deeper weathering and cover.

JORC Code, 2012 Edition – Table 1 report
Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
| Criteria | Commentary |
|---|---|
| Drilling technique | Initially 6 Reverse Circulation (RC) drill holes with face sampling hammer bit.at the Plato prospect. Subsequently, 4 NQ diamond core tails drilled. |
| Drill sample recovery | For 6 RC holes, recoveries were logged visually as a volume percentage. Each RC sample was split into 10% (for laboratory analysis) and 90%into a large green plastic bagthrough a triple tier splitter. Whole RC sample obtained. For DC holes, 100% core recovery obtained |
| Logging | RC drill chips & DC drill core have been geologically logged to a level of detail deemed appropriate for mineral exploration. RC & DC drill logs record lithology, mineralogy, mineralisation, weathering, colour and other appropriate features. All RC & DC logging is quantitative. 6 RC drill holes reported were logged in full NQ Diamond core from holes PLRCD001, 003, 005 & 006 were geologically logged. |
| Sub-sampling techniques and sample preparation |
Diamond core was marked up for half core diamond sawing. RC samples were cyclone split. Samples were collected mostly dry. The sample preparation of RC samples follows industry best practice. All samples will be pulverized to a minimum of 85% passing 75 microns. RC samples are collected at 1m intervals from a cyclone and split into 10% and 90% representative samples. 4m Samples of equal volume were composited from 1 metre 90% green bag samples using a spear. In house blank and duplicate sampleswere inserted as 1 in 20 samples to be analysed with each batch of samples. Samples sizes are appropriate to the size of the RC chips. All RC & DC samples were sent to Minanalytical Laboratory for geochemical analysis. |
| Quality of assay data and laboratory tests |
The analytical technique used a mixed acid digest on 4m RC composite samples and 4 acid digest on 1 metre RC samples. The analytical technique used a 4 acid digest on 0.2 metre and 1 metre diamond core samples. ForRC samples, 1 in 20 samples was a Company duplicate. No Company standards were used. The Company has relied upon Minanalytical Laboratory for standards and QA/QC. |
| Verification of sampling and assaying |
The sampling techniques were reviewed in the field by the Managing Director. Significant intersections of the RCchips and diamond corewere visually verified by the Managing Director and an independent technical consultant. There have been no been twinned holes to date. Primary sampling and logging data was collected by excel templates using flat files. No Adjustments or Calibrations were made to the assay data reported.

| Location of data points | Drillhole collars were located by GPS. Elevation values were in AHD. Expected accuracy is +/- 3m for northing and easting and +/-10m for elevation coordinates. The grid system is GDA94(MGA), zone 51 The GPS is +/- 5m.A digital terrain model hasbeen derived from data collected during the airborne magnetic survey of the whole tenement. |
| Data spacing and distribution |
Thenominal drill hole spacing is 200m on northings at Plato prospect. There is insufficient data to establish geological and grade continuity at this stage. Mineralised intervals have been analysed at 1 metre, and non-mineralised samples were composited at 4 metre intervals for analysyis. |

| Orientation of data in relation to geological structure Sample security Audits or reviews |
There is no outcrop on which to base geological control. The drill section is arbitrarily east- west. Drill intersections are not true widths. |
|---|---|
| Chain of custody is managed by Toll Ipec and then Minanalyical Laboratory. RC Samples were stored at drill site and then delivered by Enterprise personnel to Toll Ipec for transport to the Perth laboratory. Preliminary logging of Diamond drill core was undertaken in the field, and core was then transported to Perth by Company personnel for detailed logging and core sawing. |
|
| No audits or reviews are required at this early stage of exploration |
Section 2 Reporting of Exploration Results
(Criteria listed in the preceding section also apply to this section.)
| Criteria | Commentary | |
|---|---|---|
| Mineral tenement and land tenure status |
The drilling is located wholly within Exploration Licence E63/1281. The tenement is 100% owned by Enterprise Metals Ltd The tenement is granted and in good standing with no known impediments to exploration. |
|
| Exploration done by other parties |
No known exploration by other parties on Plato Prospect. |
|
| Geology | Plato occurs within the Albany-Fraser Orogen which consists of gneiss, mafic rocks including gabbro with significant garnet in the metamorphic rocks. Further drilling and assaying is required to fully assess the geology and style of mineralisation. Preliminary mineralogy and petrology studies completed suggest that host rocks at Plato aremafic granulites derived from norite, gabbronorite and olivine-bearing gabbronorite protoliths, and that these drill chip samples were originally cumulate mafic rocks in a layered mafic complex. All observed samples carried sulphides that appear to be primary sulfides in terms of their mineralogy, with the typical assemblage being pyrrhotite with subordinate chalcopyrite and pentlandite. |
|
| Drill hole Information | Refer to Figure 2 for drill hole locations. |
|
| Data aggregation methods |
Where assays were composited for summary purposes, all assays were weighted by equal interval (1 m or 4m) No use of metal equivalents has been used in this report |
|
| Relationship between mineralisation widths and intercept lengths |
The geometry of mineralisation is not known fully at this early stage. Intercepts are of holes drilled at -70 dip. These are not true thicknesses. Downhole lengths only are reported. These are not true widths. |
|
| Diagrams | Revised Schematic cross section only at this early stage of exploration. |
|
| Balanced reporting | All significant results are reported. All 1 metre and 4 metre RC assay results and DC assay results reported for elements relevant to magmatic nickel sulphide search. |
|
| Other substantive exploration data |
Previous exploration results at Plato reported in ENT:ASX releases dated: 19/5/2014,6/05/2014, 2/05/2014, 1/05/2014, 30/04/2014, 28/04/2014, 21/06/2013, 19/03/2013,20/11/2012,17/09/2012 |
|
| Further work | At this stage, geology and mineralisation at Plato are not well understood. Diamond core (DC) was drilled to allow DHEM surveys and provide drill core for geology and petrology. |
