PFN CONFIRMS AND INCREASES HIGH-GRADE MINERALISATION AT JASONS PROSPECT

HIGHLIGHTS

  • PFN results significantly increase encountered grade at Jasons Prospect by 50% on average

  • Strong positive disequilibrium indicated locally, particularly on basal mineralisation in the southern project region

  • Results along trend in line with nearby historical PFN data (e.g. YAM040)

  • Strong high-grade zone identified, open to the north and south over 1km in trend extent and up to 200m wide

  • Sonic core holes planned to confirm stratigraphy and tenor of mineralisation with laboratory assaying

  • Significant intercepts encountered now include:

  • 2.5m @ 4005ppm pU3O8 (BMR043 from 105.45 - versus 1392ppm eU3O8)

  • 6.75m @ 940ppm pU3O8 (BMR050, from 103.95 - versus 524ppm eU3O8)

  • 1.5M @ 1556ppm pU3O8 (BMR008 from 90.25m - versus 1427ppm eU3O8)

  • 1.25m @ 1662ppm pU3O8 (BMR018 from 93.55m - versus 1389ppm eU3O8 )

  • 1.5m @ 1389ppm pU3O8 (BMR042 from 103.95m - versus 605ppm eU3O8)

  • 1.75m @ 1317ppm pU3O8 (BMR044 from 93.45m - versus 875ppm eU3O8)

  • PFN probe results have been independently validated as suitable for reporting

  • Field Season finished for 2016, further trend extent drilling to start in January 2017

Boss Resources Limited (ASX: BOE) is pleased to announce that the PFN data collected during the recent drilling program has been reviewed by an independent expert as suitable for reporting. The Jasons Prospect is located approximately 12km north of Boss’s Honeymoon Uranium Mine Site (Figure 1).

Field activities (Figure 2) have finished for 2016 with 54 holes drilled in total. In 2017 the program will continue targeting north- and south- trend extensions of the southern high-grade zone as well as drilling of two sonic core holes.

Prompt Fission Neutron (PFN) tools are the preferred method for assessing uranium in younger sandstone hosted uranium deposits as they can avoid the effect of radioactive disequilibrium and can provide a more accurate reading of uranium grade and mineralisation. Natural gamma derived eU3O8 grade measures uranium content indirectly as a large portion of gamma rays are emitted by[214] Bi and 214Pb, which are decay products from 238U. The PFN tool utilises pulsed neutrons to directly determine the presence of[ 235] U and results in pU3O8 grade measurements.

During the current drill program at the Jason Prospect, Boss collected PFN data using 2 PFN tools acquired with the Honeymoon Project. As part of the Company’s QA/QC procedures, an independent

expert was engaged to review both the calibration data and the resulting pU3O8 grade data prior to reporting.

Boss is pleased to note that the PFN results have confirmed and in a number of case increased the equivalent grades for the mineralisation encountered in the drill program. See Table 1 for comparisons.

Boss recognises that there is an approximately 50% average higher reading on the PFN tool when compared to the natural gamma eU3O8 grade data. The Company has designed a sonic core program to commence in January 2016 to further confirm the grade profile at the Jasons prospect. This is an important validation step prior to potentially using the PFN data in Resource estimates.

Figure 1 shows the peak per-hole grade x thickness composites (single best composite, not amalgamated) for the recent drilled holes, along with historical holes for reference. Results seen to date support the general endowment seen by historical drilling with significantly good lateral continuity of mineralisation encountered. Figure 3 shows example sections from the southern portion of the deposit. The Company is encouraged that the high grade mineralisation trend to the south is showing good trend continuity and is related to a basal feature of the Lower Eyre sands, potentially related to a basement embayment.

Table 1 summarises pU3O8 and eU3O8 significant intercepts above a nominal 250ppm eU3O8 (gamma) lower cutoff and greater than 0.5m in thickness and less than 1m of internal dilution. Holes where the PFN data was either unreliable or the hole was blocked do not have a reported pU3O8 grade assigned. Based upon logging of the drilling muds, the mineralisation encountered to date is from within sandy units of the Lower and Middle Eyre Formation and also along sand/clay interbeds and interfaces.

Boss has an approximately 70 drillhole mud-rotary program underway at the Jasons Prospect (Figure 2) which will enable further delineation and expected expansion of the current resource (currently at 2.8Mt at 840ppm eU3O8 for 5.2Mlb contained U3O8 above a 250ppm U3O8 lower cutoff) .

The gamma eU3O8 probing was undertaken by Borehole Wireline, a highly experienced South-Australian based geophysical contractor. The tool used has been calibrated in the South Australia Glenside test pits.

Calibration of PFN Tools

The PFN tools have been calibrated using four on-site test pits and also against the certified Glenside calibration pits in South Australia. For both tools used, Boss has chosen to use the most conservative calibrations available based upon four calibration runs over 6 months in 2016 at the Honeymoon test pits. It is noted that matrix differences in the Glenside pits does not allow for direct comparison between the two results. No hole size calibration factor has been used. It is noted that the PFN tools are calibrated in 120mm diameter holes, and 145mm diameter holes are being drilled on the Jasons Prospect; historically a positive calibration faction of 130% would have been used for holes of this hole diameter. Both the calibration procedures and resulting pU3O8 grade data were reviewed by an independent expert (Mr J. Oram) prior to reporting.

Full sampling and drilling details are shown in Appendix 1.

About the Honeymoon Uranium Project

The Honeymoon Uranium Project (Figure 3) is located in South Australia, approximately 80km northwest from the town of Broken Hill near the SA / NSW border. The Project consists of 1 granted Mining Lease, 5 granted Exploration Licenses, 8 Retention Leases and 2 Miscellaneous Purposes Licenses.

There are 2 main exploration regions: the Eastern Region (ELs 5215 and 5621) which hosts the Honeymoon, Brooks Dam and East Kalkaroo Resources; and the Western Region (ELs 5043, 5623 and 5622) which hosts the Gould’s Dam and Billeroo deposits.

The Project has combined JORC 2012 Mineral Resources across three main project areas of 40Mt at 650ppm eU3O8 for 57.8Mlb of contained U3O8. Including Measured Resources of 1.7MT @ 1720ppm eU3O8, Indicated Resources of 5.9Mt @ 810ppm eU3O8 and Inferred resources of 32.5Mt @ 569ppm eU3O8 reported above a 250ppm lower cutoff.

The Project also has a combined Exploration Target of between 32Mt to 78Mt at a grade of between 450ppm and 1400ppm U3O8 with a potential target endowment of between 42Mlb and 100Mlb of contained U3O8. This Exploration Target is conceptual in nature and there has been insufficient exploration to estimate a Mineral Resource. It is uncertain if further exploration will result in the estimation of a Mineral Resource. See announcement of 8th December, 2015, for further information.

The Honeymoon Uranium Project is located in the southern part of the Callabonna sub-basin in South Australia. Uranium mineralisation within the project area is hosted by the Yarramba and Billeroo palaeochannels (Figure 3). These consist of Palaeogene age palaeovalleys filled by a sequence of interbedded sand, silt and clay). Thickness of the palaeochannels at Honeymoon deposit area reaches a maximum of 55m thick, and is around a depth from surface of approximately 110 metres.

The uranium mineralisation represents a classic basal channel type sandstone-hosted uranium roll-front model. This model implies the movement of oxidised, uranium-bearing fluid through a largely reduced aquifer, with mineralisation occurring at the redox front of the fluid. A geochemical zonation is associated with the roll front, including oxidation of the sands upstream (orange and yellow limonite) and abundance of pyrite/marcasites and organic matter downstream. Mineralisation is associated with discreet accumulations of organic matter and pyrite within the palaeovalley sequence.

Sampling
techniques
In-hole radiometric uranium grade data was intially determined by Borehole Wireline with eU3O8determined
from the down-hole natural gamma-logs and pU3O8. Additionally Boss is utilising it’s own PFN tools to obtain
pU3O8grades which when properly calibrated reduce the efect of radioactive disequilibrium.
All tools were maintained by specialised electronic companies and technicians based in Adelaide.
Calibration for the PFN tool was regularly undertaken using in-house calibration pits available at the Honeymoon
Project and for the gamma tools externally, at the certified calibration facilities at Glenside, ConyIngham St,
Adelaide. Standard industry procedures were used for geophysical logging of the drill holes and estimation from
thegeophysical logs for the eU3O8 (from thegamma-raylogs)andpU3O8 (from the PFN instruments) grades
Drilling
techniques
The holes were drilled by Watsons Drilling using the mud rotary method. The typical hole diameter is
14.5cm.
Drill sample
recovery
Not applicable. Calliper readings indicate that hole size diameters are predominantly consistent.
Logging Chip samples are collected every 2m and piles are s photographed and geologically logged.
Documentation has included colour, grain size, texture, sorting, alteration and oxidation state. All
mineralised intervals were geologically logged with logging standards compliant with the industry
standards.
Sub-
sampling
techniques
and sample
preparation
QA/QC of the geophysical data has included systematic control of the depth logged and control of the
recorded U3O8grade values. Geophysical tools estimate uranium content at large volumes,
approximately 25 to 40 cm radius. The volume is sufficiently large allowing accurate measure of the
grade.
Quality of
assay data
and
laboratory
tests
Company Geophysical tools used to collect data include:
• Auslog Gamma (with Guard) S422
• Prompt Fission Neutron tool PFN#27
• Prompt Fission Neutron tool PFN#32
• Gamma combined with guard S058
• Auslog 3 arm calliper A326
Borehole wireline tools used to collect data include: Natural gamma, Induction, SP, Density, Spectral
Gamma, deviation and 3 arm calliper
Holes were logged in down and up directions, which provided a good control of logging consistency.
All geophysical tools were regularly calibrated, using in-house facilities and the certified laboratories in
Adelaide.
QA/QC of the geophysical data has included systematic control of the depth logged and control of the
recorded eU3O8grade values.
The winches in the logging truck have their depth calibration checked periodically.
Verification
of sampling
and assaying
The gamma-log data were additionally validated against the PFN logs. PFN grade data was only
reported where there was a good correlation between PFN and gamma anomalies; and where PFN tool
readings were considered to be robust.

Location of
data points
Positions are set out using a Garmin handheld GPS, after drilling.
The projection adopted for surveying is GDA 94, MGA zone 54 with AHD elevation. All surveys were tied
to the existing registered base stations.
Topographic control was improved by Aerometrx Pty. Ltd flying 10cm pixel aerial photography which was
rectified usingregistered survey points installed at site beforeplant construction began.
Data spacing
Drill spacing is approximately 100m x 180m. Uranium grade is composited to 0.25cm to aid in
and
distribution
interpretation.
Orientation
of data in
relation to
geological
structure
All holes are drilled vertically which provides an accurate intersection of the flat laying mineralised
bodies.

status
The Project consists of 1 granted Mining Lease, 5 granted Exploration Licenses, 8 Retention Leases and
2 Miscellaneous Purposes Licenses.
The Mining license expires in 2023, exploration licenses expire in 2017 (except EL 5043 which expires in
2016).
Exploration
done by other
parties
The Honeymoon deposit and surrounding areas of the Yarramba palaeochannel have been intensely
explored and systematically drilled starting from 1969.
The Honeymoon Project was evaluated several times, with the degree of details varying from scoping
studies to bankable feasibility undertaken in 2006. Resource estimates have been made from 1998 to
2016.
Geology Palaeochannel type sandstone hosted uranium roll and tabular style.
Drill hole
Information
See previously exploration announcements and drillhole collar diagrams. The topography in this region
is predominantly flat. All holes were drilled vertically with an average hole length of approximately
120m.
Data
aggregation
methods
Mineralised intervals were chosen based upon a nominal 250ppm U3O8cutoff and over 50cm for
reporting. Consideration was given to mineralisation defined by a combination of PFN eU3O8and
natural gamma eU3O8co-existent intervals.

Relationship
between
mineralisation
widths and
intercept
lengths
Drill traverses are oriented at right angle across the domain strike.
Holes are drilled vertically down. All holes have been down-hole surveyed with only minimal deviation
identified (e.g. <2m over 100m).
Diagrams Appropriate and relevant diagrams have been included in the announcement. The following diagram
illustrates currently drilled holes.
Balanced
reporting
Balanced reporting has been adhered to. See previous exploration announcements.
Other
substantive
exploration
data
Mineralisation is still open along the strike of the domain.
Further work Sonic holes will be planned to enable a fuller understanding of practical disequilibrium and
sedimentological conditions within the deposit. Chemical analysis of core will be an important step in
validating the observed PFN grades and disequilibrium effect prior to use of this data in resource
estimation.
