- 18.25m @ 1.63% Ni from 4.75m, including 13.75m @ 1.83% Ni from 9.25m
- 16.5m @ 1.49% Ni from surface, including 10m @ 1.85% Ni from 6.5m

Axiom Mining Limited ('Axiom' or 'the Company') is pleased to announce material progress with drilling at the Isabel Nickel Project, Solomon Islands.
The drilling program is designed to confirm the historical data compiled by the International Nickel Company Limited (INCO) and Kaiser Engineers International Inc (Kaiser Engineers) and test the potential for high grade nickel in saprolite beneath the limonite mineralisation.

Axiom CEO Mr Ryan Mount said, "Drilling has intersected high grade transition and saprolite ore beneath some of INCO's bulk test sites-confirming our geological model that higher grade saprolite zones exist at greater depth.
"We will complete our orientation drilling over the next two months, and then progress to resource definition drilling, initially targeting four to seven million tonnes."
To date, 27 core holes have been completed, with drilling continuing (Figures 1 and 2).
Axiom has also made progress in areas of project infrastructure and logistics, approvals and permitting, safety and environmental management, and community and stakeholder engagement.

Project progress
The Isabel Nickel Project has undertaken significant progress since drilling commenced in November
2014-in addition to the exploration results detailed above, other key activities have been undertaken including:
• excavator pitting to test wall stability, ease of mining, mining characteristics and 3D geological structures
• reconnaissance of all mineralised sites on the tenement
• static water level measurements (within drill holes) to evaluate ground water as well as in-situ ore characteristics
• acquisition of detailed contour data for the project evaluation.
3
Figure 3 - Isabel Nickel Project - tenement locality
Work has also progressed on the infrastructure, transport and logistics requirements of the project, including:
• repairs to existing roads, tracks and jetty infrastructure plus the eststablisment of new roads
• establishment of an initial 70-person camp
• establishment of logistics and transport systems between Honiara, Santa Isabel Island and various sites
• preliminary solar drying of test samples to evaluate mining and transport requirements
• evaluation of transport logistics (shipping channels, marker sites, depths).
Safety and environmental protocols and procedures are in place for exploration, and are currently being developed for mining operations.

Environmental baselines studies are underway and monitoring equipment has been installed.
Axiom has also begun discussions with Anitua to provide mining services, and with interested parties to undertake metallurgical testing of limonite, transition and saprolite ore horizons by a variety of hydro and pyro metallurgical processes.
About the Isabel Nickel Project
The Isabel Nickel Project is considered to be one of the largest nickel laterite deposits in the Pacific. The project has been extensively explored by mining and engineering industry leaders, International
Nickel Company Limited (INCO) and Kaiser Engineers International Inc (Kaiser Engineers).
Axiom Mining holds a 50-year registered lease and Prospecting Licence over the Isabel nickel deposit and is targeting the establishment of a direct shipping of ore (DSO) operation by late 2015.

In cases where 'industry standard' work has been done this would be relatively simple (eg
'reverse circulation drilling was used to obtain
1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay'). In other cases more explanation may be required, such as where there is coarse gold
that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure
of detailed information.

• Handheld XRF analysers were used in field for initial analysis on 25cm intervals for control then 10cm

All diamond core holes were:
• marked up for recovery calculations
• geologically marked up and logged
• photographed
• weighed by tray one day after drilling (wet density less water added in drilling process)-selected core was weighed weekly and at laboratory for both dry density and solar drying responses.
Core was geotechnically logged for hardness, fractures, fracture orientation, recovery and mining characteristics.
All laterite intersections were analysed by either handheld XRF analyser or standard laboratory techniques for both mine grade values and trace elements.
