OUTSTANDING DRILL RESULTS CONFIRM A 5.6KM HIGHGRADE EXTENSION OF BOONANARRING DEPOSIT
_____________
Highlights
-
Drilling results confirm a 5.6km northern extension of the Boonanarring Mineral Resources area.
-
Outstanding high-grade intersections of 8m @ 23.8% HM in IX00245, 8m @ 21.1% HM in IX00244 and 8m @ 16.3% HM in IX00250.
Image Resources NL (Image or the Company) (ASX: IMA) is pleased to announce that the results of a recent drill programme have confirmed a 5.6km extension of high-grade mineralisation associated with the Boonanarring mineral sands deposit . Boonanarring is arguably the highest grade, high-zircon undeveloped mineral sand deposit in Australia. In addition, the Company is in the final stages of completing a bankable feasibility study and is planning to develop the project with a goal of first production in early 2018. The indication of a significant extension of high-grade mineralisation for this deposit adds to the upside potential of the project.
The Boonanarring deposit has estimated mineral resources of 43.8M tonnes at 5.6% heavy minerals (HM) with 18.1% of the HM as high value zircon and with 72% of the HM as valuable heavy minerals (VHM) (ASX release 13/01/2017). The area containing the current mineral resources at Boonanarring stretches 13.2km to the south on the east side of Brand highway. The new drilling results confirm the high-grade mineralisation extends to the north on the west side of the Brand highway for an additional 5.6km.
The recent drill program was located within a road reserve on the Quinns Hill tenement (E70/3100). Ten drill holes for a total of 468m were completed in a programme designed to test the extension of the high-grade eastern strand of the Boonanarring mineral sand deposit, adjacent to and to the west of the Brand Highway. The design of the programme was based on an extrapolation of previous drilling by Image and limited historic drilling by Iluka.
Assay results from this drilling programme are outstanding and clearly confirm the extension of the high-grade Boonanarring eastern strand northwards for 5.6km.
Previous reported drilling by Image (ASX release 13/07/2015) on the southwest side of the Brand highway included results of 8m @ 21.6% HM from 38m in drill hole IM0083 and 14m @ 17.9% HM from 40m in drill hole IX00103. The new drilling results (Table 1 below) represent a continuation of the high-grade eastern strand for another 3.5km northwards beyond the location of drill holes IM0083 and IX00103.

Hole IX00250 of the current programme starts on the eastern edge of the Brand Highway and contains 8m @ 16.3% HM and moving north, the high-grade mineralisation is present on the western edge of the Brand Highway and drill hole IX00244 contains 8m @ 21.1% HM from 23m and IX00245 contains 8m @ 23.8% HM from 27m (Figures 1 and 2). Whereas the northernmost intersection of mineralisation was intersected by an historic drill hole RG45 by Iluka which contains 6m @ 6.7% HM from 31m and is open at depth as some of the holes drilled by Iluka did not reach the bottom of mineralisation.
Even though this limited 10-hole drilling programme has demonstrated that the high-grade eastern strand is present over 5.6km, further drilling is required to outline a resource as in some cases only 1 to 2 holes were drilled every 200–400m. Land access is currently being sought and further infill and extension drilling will be included in future drilling budgets.
It is not possible to make a determination at this time regarding the methodology or potential economics of mining in this extended area due to the location of the Brand highway and some gas pipelines. However, there is precedent regarding approvals to allow mining in areas near transportation and other infrastructure.
Executive Exploration Director, George Sakalidis commented, “The extraordinary high-grade results of this current drilling programme north of Boonanarring have the potential to add significantly to the Company’s inventory of high grade mineral sand deposits in the North Perth Basin. The Company has also shown that the Boonanarring deposit is significant in size, as this drilling shows potential to be larger than 18.8km in length, with further upside potential both to the north and south.”
Managing Director, Patrick Mutz commented “The results of the recent drilling programme are extremely positive given the Company’s current drive to move the Company to first production at Boonanarring in early 2018. The upside potential of additional high-grade mineralisation within pumping distance of the planned location of the wet concentrator plant at Boonanarring could add significant value to the project.”

At the drill site, Image’s geologist estimates sample recovery qualitatively (as good, moderate or poor) for each 1 m down hole sampling interval. Specifically, the supervising geologist visually estimates the volume recovered to sample and reject bags based on prior experience as to what constitutes good recovery. Image found that of the 65 samples that have a grade ≥ 2% HM that are the subject of this release, all 65 (100%) have good recovery. |

Image’s supervising geologist logs the sample reject material at the rig and pans a small sub sample of the reject, to visually estimate the proportions of sands, heavy mineral sands, ‘slimes’ (clays), and oversize (rock chips) in each sample, in a semi-quantitative manner. The geologist also logs colour, grainsize, an estimate of induration (a hardness estimate) and sample ‘washability’ (ease of separation of slimes from sands by manual attrition). To preclude data entry and transcription errors, the logging data is captured into a digital data logger at the rig, which contains pre-set logging codes. No photographs of samples are taken. The digital logs are downloaded daily and emailed to Image’s head office for data security and compilation into the main database server. Samples visually estimated by the geologist to contain more than 0.5% HM (by weight) are despatched for analysis along with the 1 m intervals above and below the mineralised interval. The level and detail of logging is of sufficient quality to support any potential future Mineral Resource Estimates. All (100%) of the drilling is logged. Geotechnical logging is not possible for the style of drilling used, however the logging is acceptable for metallurgical sample selection if required. |

The laboratory despatch samples are prepared by Western Geolabs (in Bellevue Western Australia) by drying the sample for 5 to 8 hrs in an oven at 110C. The dry weight is recorded using a laboratory digital scale. The dried sample is then crushed (using manual pummelling) until all clay and sand materials in the sample pass through a 3.3 mm screen. In samples where (>3.3 mm) rock fragments are found after pummelling and screening, the mass of the fragments is recorded and the material discarded. The <3.3 mm sample is then hand mixed prior to splitting through a single tier riffle splitter (16 chutes each with 8 mm aperture), as many times as required to prepare a 100 g ± 5 g sub sample. The actual mass retained is recorded using a laboratory digital scale. The riffle splitter sub sample is then wetted, undergoes further manual attrition to break up clays, before the <63m clays (slimes) are washed from the sample (de-sliming) using a jet wash and 63m screen. The <63m slimes (clays) are discarded and the >63m sub sample is placed in a metal tray and oven dried. When dry, the >63m sub sample is put through a 1 mm sieve and the mass of the screen oversize (>1 mm) is recorded on a digital balance. The oversize is then discarded. The de-slimed sand fraction (>63m & < 1mm) sub sample is then weighed on a digital scale before being separated into two fractions by mixing the sample in a glass separation funnel with a heavy liquid (TBE) of density 2.95 g/cm3. Once sufficient time has passed to allow the sample to separate and settle, the <2.95 g/cm3, ‘floats’ fraction is collected and discarded. The <2.95 g/cm3, ‘sinks’ fraction is collected from the funnel into a filter paper, then washed with acetone to remove the TBE. The sinks are then dried and the mass recorded on a digital scale. |

| From the process above the laboratory reports the wet mass received, dry received mass, the mass of (>3.3 mm) rock fragments or coarse oversize (if any), the mass of the 100 g± 5 g, sub sample, and the mass of the (HM) sink fraction. The procedure can be considered a total analysis for mass concentration of heavy minerals in each sample. The method is also consistent with best industry practices employed by mineral sands explorers in the Perth Basin region. For quality control the laboratory: Uses certified masses to verify daily the accuracy of all laboratory mass scales. Prepares a replicate sample at a frequency of 2 for every 25 routine samples analysed. Uses a hydrometer to test daily the density of the TBE used for HM separation For each laboratory despatch (ranging from150 to350 samples) Image includes blind standard reference samples (SRMs) that contain known (to Image) concentrations of heavy and valuable heavy minerals. Image inserts the SRMs, at a frequency of 1 in 30 sample submitted to the laboratory for resource style drilling. Image submitted 3 SRM’s for the resource style drilling subject to this release. Image selected and submitted for analysis 7 field-replicate samples from field-sample replicates collected to quantify field sampling precision. Blanks samples for testing of cross contamination are not deemed necessary for the style of mineralisation under consideration. |

Logging is captured at the rig using a data recorder, downloaded daily and emailed to head office data services for incorporation into the main database. Assay results from the laboratory are received by email in standard spreadsheet templates and merged with logging results in-house. There are no adjustments to original laboratory results. |
| Location of data points |
Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Specification of the grid system used. Quality and adequacy of topographic control. |
The drill hole collar locations are captured by one of Image’s rig team following the completion of each drill hole, using a hand held GPS with nominal accuracy of±15 m. Elevations have also been determined with hand-held GPS and this adjusted post drilling using DEM data. More accurate locations will be determined in future by a registered surveyor using DGPS equipment where necessary. The grid system for reporting results is the MGA Zone 50 projection and the GDA94 elevation datum. No topographic control has been considered at this time. |
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. Whether sample compositing has been applied. |
The drill holes reported in this release are located at several prospects on varied spaced drill lines (between 200 m and 400 m) along the strike of mineralised strands. No sample compositing has been applied – all results are from 1 m long down hole sample intervals. |

JORC Code, 2012 Edition – Table 1
Section 1 Sampling Techniques and Data
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Orientation of data in relation to geological structure |
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
All drill holes are vertical and intersect sub-horizontal strata. As such Image considers that it is highly unlikely that the orientation of drilling relative to the well understood structure of minerals sands strands, would result in a sampling bias. |
| Sample security | The measures taken to ensure sample security. |
All samples are collected from site by Image’s staff as soon as practicable once drilling is completed and then delivered to Image’s locked storage sheds. Image’s staff also deliver samples to the laboratory and collect heavy mineral floats from the laboratory, which are also stored in Images locked storage. Image considers there is negligible risk of deliberate or accidental contamination of samples. Occasional sample mix-ups are usually corrected using Images checking and quality control procedures. |
| Audits or reviews | The results of any audits or reviews of sampling techniques and data. |
The results and logging have been reviewed internally by Images senior exploration personnel including checking of masses despatched and delivered, checking of SRM results, and verification logging of significant intercepts. |
