MABILO PROJECT

Overview of the Quarter

The September Quarter focused drilling on the North Mineralised Zone with the aim of improving confidence and converting inferred resources to indicated resources as well as extending the strike length. Multiple high grade intercepts were reported with wide shallow intervals of magnetite skarn continuing to validate the geological model. The drilling highlighted the North Mineralised Zone as a significant part of the projects potential total mineral resource.

Previous phases of work focused on drilling out the modelled magnetite body in multiple directions. The revised geological model recognises the North Mineralised Zone as being an off-set continuation of the Southern Mineralised Zone (Figure 2). This model has been validated with multiple drill holes confirming the geological model and has increased the strike potential of the North Mineralised System .

A number of high grade intercepts were reported to the ASX on 17th August including drill hole MDH-111 which intersected multiple high grade mineralized zones (5m @ 3.76g/t Au & 3.92% and 9m @ 1.99g/t and 6.52% Cu) within a broad magnetite skarn intercept (54.1m @ 2.30g/t Au and 3.39% Cu from 63 meters). The drill hole is currently suspended, awaiting Galeo’s recommencement of drilling and remains within mineralized magnetite skarn.

Work on the Feasibility Study continued during the quarter focusing on metallurgical work, infrastructure studies, water balance and management, TSF options, port option studies and seismic/geotechnical design considerations.

Project Background

The Mabilo Project is located in Camarines Norte Province, Eastern Luzon, Philippines. It is comprised of one granted Exploration Permit (EP-014-2013-V) of approximately 498 ha and two Exploration Permit Application (EXPA-000188-V) of 2,737 ha and (EXPA 0000 209-V) of 498 ha.. The Project area is relatively flat and is easily accessed by 15 km of all-weather road from the highway at the nearby town of Labo.

Massive magnetite mineralisation containing significant copper and gold grades occurs as replacement bodies together with mineralized garnet skarn and calc-silicate altered rocks within a sequence of hornfelsed sediments of the Eocene aged Tumbaga Formation. The garnet and magnetite skarn rocks were extensively altered by argillic retrograde alteration and weathering prior to being covered by 25-60 metres of post mineralisation Quaternary volcaniclastics (tuff and lahar deposits) of the Mt Labo Volcanic Complex. The deposits are localised along the margins of a diorite stock which does not outcrop within the Exploration Permit.

The primary copper mineralisation (predominantly chalcopyrite with lesser bornite) occurs as disseminated blebs and aggregates interstitial to magnetite grains and in voids within the magnetite. A strong correlation between gold and copper values in the un-weathered magnetite skarn indicates the gold is hosted by the chalcopyrite. A late stage phase of sulphide mineralisation (predominantly pyrite) veins and locally brecciates the magnetite mineralisation.

Figure 1. RTP ground magnetic image with modelled South, North and East magnetic bodies.

In places the more shallow upper parts of the magnetite skarn bodies were weathered to form hematite skarn. Copper in the weathered zone was remobilised forming highgrade supergene copper zones (chalcocite and native copper) at the base of the weathering profile. The gold was more variable, remobilised throughout the hematite skarn and is domained within garnet skarn and calc-silicate altered country rocks in places. The average iron grade of the hematite skarn is consistent with the magnetite skarn.

Sierra discovered the mineralisation in 2012 during a reconnaissance drilling program targeted on magnetic anomalies from a ground magnetic survey conducted by a former explorer. Sierra subsequently conducted a new ground magnetic survey in early 2013, remodeled the data and commenced a second phase of drilling in mid 2013.

Extensive drilling has been undertaken during 2014 with significant extensions in known strike beyond the magnetic model in the North and South directions. A total of 69 drill holes totaling 11,231m were used for the maiden resource estimate (ASX released on the 24[th] November 2014). Drilling is ongoing and total of one hundred and eight diamond drill holes have been completed at the end of the Quarter with further drilling ongoing. The current resource is open down dip, down plunge and along strike, with all mineralization found to date being shallow enough to be amenable to open pit mining techniques.

North Mineralised Zone

Drilling during the September quarter focused on the North Mineralised Zone, extending the mineralised system to the North and down dip. Significantly all drilling was is in good agreement with the geological model and continues to demonstrate grade and thickness continuity. Significant intercepts are summarised in Table 1 and detailed below.

The North Mineralised Zone is emerging as a significant contributor to the potential endowment of the Mabilo Project. The Mabilo System is split into the North Mineralised Zone and South Mineralised Zone with a combined strike of 625 meters of high grade magnetite skarn. Magnetite skarn replacement of marble correlates with the Southern Mineralised Zone with the marble skarn interface observed to be approximately 50m shallower in the North Body. The system remains open beyond the magnetic model and in multiple directions (Figure 2).

MDH-109

MDH-109 (Figure 5) was designed to test up-dip extent and continuity of mineralization defined by MDH-107 and down dip continuity of MDH-045 (Reported to ASX 13[th] May 2013 by Sierra Mining). Drilling intersected a relatively thin oxide gold zone followed by copper oxide zone, with strong copper depletion true width has not been determined due to the extensive patchy oxidation of primary magnetite.

MDH-111

MDH-111 (Figure 6) is designed to follow up on a section with a number of historical drill holes MDH-36, MDH-50, MDH-52 and MDH-54 which intersected magnetite and frequently terminated in marble. The new interpretation infers the historical drilling to be the interface of skarn with marble. Drilling the correct orientation has successfully intersected the true thickness of mineralization with drilling temporarily paused within magnetite skarn. True width has not been determined at this time as the drill hole is paused within mineralised magnetite skarn.

  • Site layout options finalized.

Feasibility Study

Work continued on the Definitive Feasibility Study during the quarter. Along with the metallurgical test work, work was conducted on environmental studies and infrastructure studies.

Knight Piesold Pty Ltd has also made significant progress with the water balance and management, TSF design and seismic/geotechnical design considerations for the Definitive Feasibility Study.

The Study is on track for completion later in the fourth quarter of the 2015 calendar year.

BUNAWAN PROJECT

The Bunawan Property is located in the east of Mindanao Island in Agusan del Sur Province, approximately 190km north-northeast of Davao and adjacent to the Davao – Surigao highway.

Work continued on ground mapping and preparation for geophysical programs in the Mahunoc region. Equipment refurbishment and the need for new cables delayed the start of the Gradient Array - Induced Polarization Resistivity Survey program until early next quarter.

Community development programs and Indigenous people programs continued during the quarter.

OTHER PROJECTS

The Bahayan Project is 6,924 hectares in size and is located approximately 50km south of the Bunawan Property. The Bahayan area hosts several alteration and vein zones, all typical of those formed marginal to porphyry intrusions and characterized by hydrothermal alteration with quartz-sulphide style vein gold mineralization.

Work at Bahayan during the quarter included –

  • Geological mapping

  • Rock chip sampling

  • Completion of line clearing

  • Preparation work for the geophysical survey (ground magnetics) at Cogonon.

recovery.
The majority of the mineralisation is in fresh rock where recoveries are greater
than 90%. Most mineralisation occurs in wide intersections of massive
magnetite skarn with relatively uniform copper and gold grades. Core loss
occurs in fracture zones but is usually not a significant problem i.e. the core lost
in fracture zones is unlikely to have been significantly higher or lower grade
than the surrounding material. In the weathered hematitic oxidised zones some
core loss is unavoidable, but overall recovery is generally >90% and the core
loss is volumetrically minor in the mineralised zones. In areas of poor recovery,
the sample intervals are arranged to coincide with drill runs, thus areas of
different core loss percentage are specific to individual samples which can be
assessed when interpreting analytical results and modelled in future resource
estimation studies. Where an area of 100% core loss is identified the sample
intervals are marked to each side of the zone and the zone is designated “No
core” and assigned zero value in the various log sheets and geochemical
database.
There is no discernible relationship between core recovery and grade. The

Logging Whether core and chip samples have been geologically
and geotechnically logged to a level of detail to support
appropriate Mineral Resource estimation, mining
studies and metallurgical studies.
The diamond drill core is photographed and logged in
a number of logging sheets including a geological log, a
structural log and a geotechnical log, which is
appropriate for mineral resource estimates and mining
studies, neither of which have been undertaken at this
stage.
Whether logging is qualitative or quantitative in nature.
Core (or costean, channel, etc.) photography.
Most of the geological logging is a mixture of qualitative
(descriptions of the various geological minerals and
features) and quantitative (numbers and angles of
veins etc). Photos are taken of all core (both wet and
dry) which can be considered quantitative.
The total length and percentage of the relevant
intersections logged.
All core is initially logged in the various logging sheets
noted above and intervals are marked out for sawing
and sampling. Not all core has been sampled to date.

Sample lengths are one metre (or less to coincide with
lithological breaks). All core from mineralised zones
and the immediate surrounding rocks was initially
preparation sawn in half to provide a better surface for geological
logging. Half core is collected for analysis and the other
half retained for reference and or metallurgical
testwork.
If non-core, whether riffled, tube sampled, rotary split,
etc. and whether sampled wet or dry.
All sampling reported is of diamond drill core.

All half core samples were bagged, labelled and sent to
an ISO certified independent laboratory where samples
are dried, crushed and pulverised to 95% of the sample
passing a 75μm sieve.
Quality control procedures adopted for all sub-sampling
stages to maximise representivity of samples.
The drilling was reconnaissance in nature and no field

3] a geotechnical log of all core recording RQD, defects,
fabrics;
4] a geochemical log of assay results.
The drilling results reported are from the first phase of
reconnaissance drilling and the data has not been
incorporated into a dedicated Project computer
database at this stage. All logging and assay data has
been validated and archived and is available for future
reference. Hard copies of all logging sheets are kept at
both the Project office in Bunawan town and the Davao

Sample
security
The measures taken to ensure sample security. Chain of custody was managed by the company
employees. Core was placed in core trays by the drilling
crew and kept at site under constant watch by
Company employees prior to being transported from
the drill site by Company employees in a Company
vehicle to the core shed where core was logged and
sawn core samples prepared for dispatch.
Samples were packed in boxes and sent directly from
the core shed to the laboratory sample preparation
facility in General Santos town using a local transport
company. Remaining core is kept in the Company core
yard which is in a secure compound at Bunawan which
is guarded at night.
