Commentary

Sampling techniques

 Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling.

 Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.

 Aspects of the determination of mineralisation that are Material to the Public Report. In cases where 'industry standard' work has been done this would be relatively simple (e.g. '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 (e.g. submarine nodules) may warrant disclosure of detailed information.

 The mineralization was sampled by Reverse Circulation (RC) on nominal 20m x 20m grid spacing. The holes were generally drilled towards grid east at -60 degrees to optimally intersect the mineralized zones.

 The drill hole locations were designed to allow for spatial spread of samples across multiple mineralized zones and different rock types. All RC recovered samples were collected and passed through a cone splitter. Prior to drilling the drill hole locations were pegged using either contract surveyors or hand held GPS units. After drilling, all drill hole locations are picked up by contract surveyors using a RTK system. All drill holes greater than 80m drilled by EXG used in the Ore Resource calculations were down hole surveyed by contractors using specific non-magnetic tools.

 All RC drilling was sampled on one metre down hole intervals. The recovered samples were passed through a cone splitter and a nominal 2.5kg - 3.5kg sample was taken to a Kalgoorlie contract laboratory. Samples were oven dried, reduced by riffle splitting to

3kg as required and pulverized in a single stage process to 85%

passing 75 µm. The sample is then prepared by standard fire assay

techniques with a 50g charge. Approximately 200g of pulp material is returned to Excelsior for storage and potential assay at a later date. Samples were oven dried, crushed to a nominal 10mm by a jaw crusher, reduced by riffle splitting to 3kg as required and pulverized in a single stage process to 85% passing 75 µm. The sample is then prepared by standard fire assay techniques with a 50g charge. Approximately 200g of pulp material is returned to Excelsior for storage and potential assay at a later date.

Drilling techniques

 Drill type (e.g. core reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc).

 All assays reported in this announcement have come from RC drilling using a drilling contractor. The RC drilling system employed the use of a face sampling hammer and a nominal 146mm diameter drill bit.

Drill sample recovery

 Method of recording and assessing core and chip sample recoveries and results assessed

 Measures taken to maximise sample recovery and ensure representative nature of the samples

 All RC 1m samples are logged for drilling recovery by a visual estimate and this information is recorded and stored in the drilling database. At least every 10th metre is collected in a plastic bag and these are weighed when they are utilized for the collection of field

duplicate samples. The weight of the sample in the plastic bag is recorded and the total sample recovery can be calculated. All samples received by the laboratory are weighed with the data collected and stored in the database. Sample loss or gain is reviewed on an ongoing basis and feedback given to the drillers to enable the best representative sample to always be obtained.

 RC samples are visually logged for moisture content, sample recovery and contamination. This is information is stored in the database. The RC drill system utilizes a face sampling hammer

which is industry best practice and the contractor aims to maximize recovery at all times. RC holes are drilled dry whenever practicable

to maximize recovery of sample.

 Whether a relationship exists between  Study of sample recovery vs gold grade does not show any bias sample recovery and grade and whether towards differing sample recoveries or gold grade. The drilling sample bias may have occurred due to contractor uses standard industry drilling techniques to ensure preferential loss/gain of fine/coarse minimal loss of any size fraction. The sample recovery vs gold grade material. is assessed on an ongoing basis throughout the drilling program.

Logging

 Whether core and chip samples have  All RC samples are geologically logged. Specifically, each interval is been geologically and geotechnically visually inspected with a hand lens and the following parameters are logged to a level of detail to support recorded where observed: weathering, regolith, rock type, alteration, appropriate Mineral Resource estimation, mineralization, shearing/foliation and any other features that are mining studies and metallurgical studies. present. This information is transferred electronically from the

geologist to the database.

 The total length and percentage of the  The entire lengths of RC holes are logged on a 1m interval basis, i.e. relevant intersections logged. 100% of the drilling is logged, and where no sample is returned due to voids (or potentially lost sample) it is logged and recorded as

such.

As part of normal procedures Excelsior examines all

standards and blanks to ensure that they are within tolerances. Additionally, sample size, grind size and field duplicates are

examined to ensure no bias to gold grade exists.

Verification of sampling and assaying

 The verification of significant  Exploration Manager, Bradley Toms and Technical Director, David intersections by either independent or Potter, have inspected drill core and RC chips in the field to verify alternative company personnel. the correlation of mineralized zones between assay results and

lithology/alteration/mineralization.

 The use of twinned holes.  A number of diamond core and RC holes have been drilled throughout the deposit to twin RC holes. These twinned holes returned results comparable to the original holes and were also used to collect geological information and material for metallurgical assessment. A number of RC holes have also been drilled that confirmed results obtained from historical drillholes.

 Documentation of primary data, data  Primary data is sent digitally every 2-3 days from the field to entry procedures, data verification, data Excelsior's Database Administrator (DBA). The DBA imports the storage (physical and electronic) data into the commercially available and industry accepted protocols. DataShed database software. Assay results are merged when received electronically from the laboratory. The responsible geologist

reviews the data in the database to ensure that it is correct and has

merged properly and that all data has been received and entered. Any variations that are required are recorded permanently in the database.

 Discuss any adjustment to assay data.  No adjustments or calibrations were made to any assay data used in this report.

detours, the laboratory then checks the physically received samples against an Excelsior generated sample submission list and reports back any discrepancies

 Drill core is transported daily directly from the drill site to Excelsior's secure core processing facility by Excelsior personnel with no detours. The core is then placed on racks within a secure shed and processed until it requires cutting. Core is then transported directly by Excelsior's staff to the Kalgoorlie laboratory where it is cut in half by laboratory staff and then sampled by Excelsior staff. The core is then prepared for assay in Kalgoorlie to the pulverizing stage whereupon the laboratory transports it using a contractor directly to their Perth based assay facility.

Mineral tenement and land tenure status

 Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings.

 The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.

 The results reported in this Announcement are on granted Mining Leases held by GPM Resources Pty Ltd, a wholly owned subsidiary of Excelsior Gold Limited.

 At this time the tenements are believed to be in good standing.

There are no known impediments to obtaining a license to operate,

other than those set out by statutory requirements which have not yet been applied for.

Exploration done by other parties

 Acknowledgment and appraisal of exploration by other parties.

 Exploration by other parties has been reviewed and is used as a guide to Excelsior's exploration activities. Previous parties have completed both open pit and underground mining, geophysic al data collection and interpretation, soil sampling and drilling. This report comments on only exploration results collected by Excelsior.

Geology

 Deposit type, geological setting and style of mineralisation.

 The mineralisation in the Zoroastrian area is predominately associated with a complex array of multiple dimensional and variable orientated quartz veins and stock works within the differentiated Zoroastrian Dolerite. In places a surficial 1-2m thick calcrete/lateritic gold bearing horizon and small near surface supergene pods exist. Recent open pits, historical workings and shafts exist within this unit throughout the Company's tenements and beyond. Detailed mapping and sampling of these workings and structural measurements from orientated diamond core drilling forms the basis of the geological interpretation.

 The mineralisation in the Navan area, as tested by the December

2014 drilling program is concentrated in near surface laterite gravels

and clays.

Drill hole

Information

 A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes:

o easting and northing of the drill hole collar

o elevation or RL (Reduced Level - elevation above sea level in metres) of the drill hole collar

o dip and azimuth of the hole

o down hole length and interception depth

 The drill holes reported in this Announcement have the following parameters applied. All drill holes completed, including holes with no significant gold intersections are reported in this announcement.

 Easting and northing are in MGA94 Zone 51
