ANNOUNCEMENT TO THE TORONTO STOCK
EXCHANGE AND AUSTRALIAN SECURITIES EXCHANGE
SUBIACO, Western
Australia, Feb.
26, 2015 /CNW/ - The Board of RTG Mining Inc. ("RTG", "the
Company") (TSX Code: RTG, ASX Code: RTG) is pleased
to announce further significant high grade gold and copper
intercepts extending mineralisation and a new high grade garnet
skarn mineralised zone in the South Mineralized Zone at the Mabilo
Project in the Philippines.
Resource drilling on the South Body designed for resource
classification conversion has intersected a new zone of mineralised
garnet skarn at shallow levels. This is the best intercept of
garnet skarn mineralisation intersected to date. MDH-095
intercepted 25.80m at 2.32% Cu and 1.63 g/t Au from shallow
downhole depths below volcanic overburden. Significant
mineralisation in this part of the system has not been intersected
previously and will be subject to follow up investigation.
Highlights of the ongoing drilling program include –
- MDH-095 Discovery of high grade Garnet Skarn mineralisation at
shallow position and magnetite intercept.
25.80 meters at 2.32% Cu and 1.63 g/t Au from
111 meters downhole.
26.60 meters at 1.99% Cu and 1.62 g/t
Au from 194 meters downhole.
- MDH-090 Deep extension of magnetite skarn mineralisation at the
deepest levels of the resource model.
11.70 meters at 1.48% Cu and 2.79 g/t Au from 307.30 meters
downhole.
The interval reported in MDH-95 is significant in that Garnet
Skarn has not previously been intercepted with significantly wide
intervals and was not the primary target of the drill hole.
The discovery of high grade garnet skarn at shallow levels
represents a new target for follow up drilling and modelling.
Subsequent follow up drilling designed to intersect the same garnet
skarn at shallow positions has been successful in delineating
similar mineralised garnet skarn subject to oxidation processes
(assays pending).
Deeper extension drill hole MDH-090 has successfully validated
the current south western limit of the geological model. This
confirms the system extends at depth and remains open, with MDH-090
being part of an ongoing campaign designed to upgrade the inferred
resource classification at depth.
ABOUT MABILO
The Mabilo Project is located in Camarines Norte Province,
Eastern Luzon, Philippines. It
comprises one granted Exploration Permit (EP-014-2013-V) of
approximately 498 ha and Exploration Permit Application
EXPA-000188-V of 2,820 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.
Drilling is ongoing and currently focused on resource
classification conversion (ASX release 24th November 2014) and extension identification to
the South Body and North Body.
MDH-095
MDH-095 was set ~55m meters Southeast of MDH-060 and drilled on the
previous section line. The drill hole was designed to confirm
the strike and down-dip extension of the magnetite
mineralisation (Figure 3). Garnet skarn has been identified in
adjacent sections (Figure 4) exhibiting intervals of patchy
chalcopyrite.
MDH-095 intercepted a 25.8m interval of retrogressed garnet
skarn with abundant coarse grained chalcopyrite from 111m downhole.
The drill hole continued to the targeted magnetite skarn
intersecting 25.60 meters of magnetite skarn from 194m down hole.
Drilling was in a shallow inclination across modelled lithology
with true thickness of the garnet skarn being approximately 23m and
magnetite being approximately 25m.

extension of the garnet skarn interval at the Labo Volcanic cover.
MDH-96 intersected oxidised garnet skarn textures with and
instances of coarse grained chalcopyrite, assays are pending. The
recently terminated drill hole on section MDH-094 passed through
mineralised garnet skarn with instances of magnetite at similar
positions with targeted magnetite skarn intersected at depth.
MDH-090
MDH-090 is located 100 meters Southwest of MDH-060. Drilling is
designed to upgrade the Inferred resource category of the current
deepest extension to the Southwest of the model. MDH-090
successfully intersected brecciated magnetite skarn from 307.30m to
318.80 meters confirming the down dip extension of the system to
over 175 meters in length with the interval in close agreement with
the resource modelling. True thickness is approximately 10
meters.

Section 1 Sampling Techniques and Data
|
|
|
Criteria
|
JORC Code
explanation
|
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.
|
- The assay data
reported herein is based on sampling of diamond drill core of PQ,
HQ and NQ diameter which was cut with a diamond core saw. Samples
are generally of 1 m length, although occasionally slightly longer
or shorter where changes in lithology, core size or core recovery
required adjustments; samples are not more than 2 m
length.
- The length of each
drill run is recorded and the recovery for each run calculated on
site and checked again at the core shed. Certified reference
standards and blank samples were submitted to assess the accuracy
and precision of the results and every 20th sample was sawn into
two and the two quarter core samples submitted for analysis
separately as a duplicate sample.
- Half core samples
were cut and sent for analysis by an independent ISO-certified
laboratory (Intertek McPhar Laboratory) in Manila. Samples were
crushed and pulverised (95% <75 μm). Gold was analysed by 50 g
fire assay and the other elements including copper and iron by
ICP-MS (Inductively Coupled Plasma Mass Spectrometry) or ICP-OES
(Inductively Coupled Plasma Optical Emission Spectrometry)
following a four-acid digest.
|
Drilling
techniques
|
- Drill type (e.g. core,
reverse circulation, open-hole hammer, rotary air blast, auger,
Bangka, sonic, etc) and details (eg 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).
|
- Drilling was by PQ, HQ and NQ
diameter, triple tube diamond coring. The core was not
orientated.
|
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.
- Whether a relationship exists between sample recovery and
grade and whether sample bias may have occurred due to preferential
loss/gain of fine/coarse material.
|
- Core recovery is initially measured
on site by trained technicians and by the supervising geologist.
Any core loss is measured, the percentage is calculated and both
are recorded in the geotechnical log for reference when assessing
assay results.
- All care is taken to ensure maximum
recovery of diamond core and drillers are informed of the
importance of core recovery. Any areas of poor core recovery are
sampled separately thus assay results can be directly related to
core 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 skarn bodies are relatively
uniform over significant lengths and the copper and gold grades are
not related to clay and fracture zones which are the main causes of
core loss.
|
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.
- Whether logging is qualitative or quantitative in nature. Core
(or costean, channel, etc.) photography.
- The total length and percentage of the relevant intersections
logged.
|
- Diamond drill core
for each entire drill hole was logged in significant detail in a
number of logging sheets including a geological log, a structural
log, a geotechnical log and a magnetic susceptibility log for the
entire drill hole. Mineralised and sampled intervals are logged
individually in a separate quantitative mineral log with
percentages of the different copper minerals being recorded. The
logging is appropriate for mineral resource estimates and mining
studies.
- Most of the
geological logging is a mixture of qualitative (descriptions of the
various geological features) and quantitative (numbers and angles
of veins and fracture zones, mineral percentages etc.). The
quantitative mineralisation log and the magnetic susceptibility log
are quantitative. Photographs are taken of all core (both wet and
dry) prior to the core being cut.
- All core, including
barren overburden is logged in the various logging sheets noted
above apart from the quantitative mineralisation log in which only
the mineralised intervals sent for geochemical analysis are logged
in greater detail.
|
Sub-sampling
techniques and sample preparation
|
- If core, whether cut or sawn and whether quarter, half or all
core taken.
- If non-core, whether riffled, tube sampled, rotary split, etc
and whether sampled wet or dry.
- For all sample types, the nature, quality and appropriateness
of the sample preparation technique.
- Quality control procedures adopted for all sub-sampling stages
to maximise representivity of samples.
- Measures taken to ensure that the sampling is representative
of the in situ material collected, including for instance results
for field duplicate/second-half sampling.
- Whether sample sizes are appropriate to the grain size of the
material being sampled.
|
- All sampling data
is from diamond drill core. Samples are of sawn half core except
for duplicate samples which are quarter core. Half core is bagged
and sent to an ISO-certified independent laboratory for analysis.
The other half retained for reference and/or further
testwork.
- Not applicable for
diamond core drilling.
- All core samples
were dried, crushed to 95% <10 mm and a 1.5 kg sub-sample is
separated using a riffle splitter and pulverised to 95% <75 μm.
A 50 g sub-sample is utilised as a fire-assay charge for gold
analysis. The sample preparation technique and sub-sampling is
appropriate for the mineralisation.
- Blank samples and
duplicate samples are submitted routinely to monitor the sampling
and analytical process and to ensure that samples are
representative of in situ material. One in every 20 samples of half
core is sawn again to produce two quarter core duplicate samples
which are submitted to the laboratory separately with different
sample numbers. A blank sample was inserted into sample batches at
every 20th sample.
- The magnetite skarn
mineralisation occurs in extensive zones of magnetite skarn with
disseminated chalcopyrite, containing gold. The sample size of
approximately 1 m core length is suitable in respect to the grain
size of the mineralisation.
- The sample size is
considered appropriate for the material sampled. It is believed
that grain size has no bearing on the grade of the sampled
material.
|
Quality of
assay data and laboratory tests
|
- The nature, quality and appropriateness of the assaying and
laboratory procedures used and whether the technique is considered
partial or total.
- For geophysical tools, spectrometers, handheld XRF
instruments, etc, the parameters used in determining the analysis
including instrument make and model, reading times, calibrations
factors applied and their derivation, etc.
- Nature of quality control procedures adopted (e.g. standards,
blanks, duplicates, external laboratory checks) and whether
acceptable levels of accuracy (ie lack of bias) and precision have
been established.
|
- All core samples
were analysed at an ISO-certified independent laboratory. Gold was
analysed by 50 g fire assay and the other elements including copper
and iron were analysed by ICP-MS or ICP-OES following a four acid
digest. The sample preparation and assay techniques are of
international industry standard and can be considered
total.
- No geophysical
tools were used for any analysis reported herein. Magnetic
susceptibility readings are used in magnetic modelling but are not
used to estimate magnetite or Fe content.
- Quality control
completed by RTG included analysis of standards, blanks, and
duplicates. Commercial Certified Reference Materials were inserted
into sample batches every 40th sample.
A blank sample was inserted every 20th
sample; the blank sample material has been sourced and prepared
from a local quarry. One in every 20 core samples is cut into 2
quarter core samples which were submitted independently with their
own sample numbers. In addition, Intertek conducted their own
extensive check sampling as part of their own internal QAQC
processes which is reported in the assay sheets. A record of
results from all duplicates, blanks and standards is maintained for
ongoing QA/QC assessment. Examination of all the QAQC sample data
indicates satisfactory performance of field sampling protocols and
the assay laboratory.
|
Verification of
sampling and assaying
|
- The verification of significant intersections by either
independent or alternative company personnel.
- The use of twinned holes.
- Documentation of primary data, data entry procedures, data
verification, data storage (physical and electronic)
protocols.
- Discuss any adjustment to assay data.
|
- Significant
mineralisation intersections were verified by alternative company
personnel.
- No twinned holes
have been drilled.
- Data documentation,
verification and storage is conducted in accordance with RTG's
Standard Operating Procedures Manual for the Mabilo Project. The
diamond drill core is manually logged in significant detail in a
number of separate Excel template logging sheets. Logging is
recorded manually on logging sheets and transcribed into protected
Excel spreadsheet templates or entered directly into the Excel
templates. The data are validated by both the Project Geologist and
the company Database Manager and uploaded to the dedicated project
database where they are merged with assay results reported
digitally by the laboratory. Hard copies of all logging sheets are
kept at the Project office in Daet.
- No adjustments have
been made to assay data.
|
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.
|
- Drill-hole collars
are initially surveyed with a hand-held GPS with an accuracy of
approximately +/- 5 m. Completed holes are surveyed by an
independent qualified surveyor on a periodic basis using standard
differential GPS (DGPS) equipment achieving sub-decimetre accuracy
in horizontal and vertical position.
- Drill collars are
surveyed in UTM WGS84 Zone 51N grid.
- The Mabilo project
area is relatively flat with total variation in topography less
than 15 m. Topographic control is provided by DGPS
surveying.
|
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.
|
- Drill holes are
planned on a nominal grid with 20 m between drill holes on 40 m
spaced lines.
- The drill hole
spacing was designed to determine the continuity and extent of the
mineralised skarn zones. Based on statistical assessment of drill
results to date, the nominal 40 x 20 m drill hole spacing is
sufficient to support Mineral Resource estimation.
- No compositing of
intervals in the field was undertaken.
|
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.
|
- No bias
attributable to orientation of sampling upgrading of results has
been identified.
- No bias
attributable to orientation of sampling upgrading of results has
been identified.
|
Sample
security
|
- The measures taken to ensure
sample security.
|
- Chain of custody is managed by RTG employees.
Samples were stored in secure storage from the time of drilling,
through gathering and splitting. Remaining core is kept in a secure
compound at the Company regional office in Daet town and guarded at
night. Samples are sent directly from the core shed to the
laboratory packed in secured and sealed plastic drums using either
Company vehicles or a local transport company. A standard Chain of
Custody form is signed by the driver responsible for transporting
the samples upon receipt of samples at the core yard and is signed
by an employee of the laboratory on receipt of the samples at the
laboratory. Completed forms are returned to the Company for
filing.
|
Audits or
reviews
|
- The results of any audits or
reviews of sampling techniques and data.
|
- The sampling techniques and QA/QC data are
reviewed on an ongoing basis by Company management and independent
consultants.

|
- The Mabilo Project
is covered by Exploration Permit EP-014-2013-V and Exploration
Permit Application EXPA-000188-V. EP-014-2013-V was issued to Mt
Labo Exploration and Development Corporation ("Mt Labo"), an
associated entity of RTG Mining Inc. There is a 1% royalty payable
on net mining revenue received by Mt Labo in relation to
EP-014-2013-V.
Mt Labo has entered
into a joint venture agreement with Galeo Equipment and Mining
Company, Inc. ("Galeo") to partner in exploring and developing the
Mabilo and Nalesbitan Projects. Galeo can earn up to a 36% interest
in the Projects, down to 200 m below surface, by contributing
approximately US$4,250,000 of exploration drilling and management
services for the Projects over a 2 year period.
In November 2013,
Sierra Mining Limited ("Sierra"), a wholly owned subsidiary of RTG,
and Galeo signed a Memorandum of Understanding ("MOU") setting out
proposed changes to the joint venture agreement to remove the depth
limit of 200 m from the agreement and provide for additional
drilling of 5,000 m below 200 m. The MOU also provides for Galeo to
be granted its 36% interest up front with the ability for RTG to
claw-back any interest deemed not earned at the end of the
claw-back period. The amendments to the JV Agreement are subject to
Sierra shareholder approval.
Sierra has also entered
a second MOU with Galeo whereby Galeo can earn an additional 6%
interest in the joint venture by mining the initial 1.5 Mt of waste
at Mabilo or Nalesbitan and other requirements including assistance
with permitting. The MOU is subject to a number of conditions
precedent, including Sierra shareholder approval.
- The tenure over the
area currently being explored at Mabilo is a granted Exploration
Permit which is considered secure. There is no native title or
Indigenous ancestral domains claims at Mabilo.

- Acknowledgment and appraisal
of exploration by other
parties.
|
- The only significant previous exploration over
the Mabilo project area was a drilling program at another site
within the tenement and a ground magnetic survey. RTG (or its
predecessor Sierra) has reported this data in previous reports to
the ASX and used the ground magnetic survey as a basis for initial
drill siting. Subsequently RTG conducted its own ground magnetic
survey with closer spaced survey lines and reading intervals which
supersedes the historical program. There was no known previous
exploration in the area of the reported Mineral
Resource.
|
Geology
|
- Deposit
type, geological setting and style of mineralisation.
|
- Mineralisation at Mabilo can be defined as a
magnetite-copper-gold skarn which developed where the
magnetite-copper-gold mineralisation replaced calcareous horizons
in the Eocene age Tumbaga Formation in the contact zone of a
Miocene diorite intrusion.

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:
- easting and northing of the drill hole collar
- elevation or RL (Reduced Level – elevation above sea level in
metres) of the drill hole collar
- dip and azimuth of the hole
- down hole length and interception depth
- hole length.
- If the exclusion of this information is justified on the basis
that the information is not Material and this exclusion does not
detract from the understanding of the report, the Competent Person
should clearly explain why this is the case.
|
- All relevant drill
hole information has been previously reported to the ASX. No
material changes have occurred to this information since it was
originally reported.
- All relevant data
has been reported.
|
Data
aggregation methods
|
- In reporting Exploration Results, weighting averaging
techniques, maximum and/or minimum grade truncations (e.g. cutting
of high grades) and cut-off grades are usually Material and should
be stated.
- Where aggregate intercepts incorporate short lengths of high
grade results and longer lengths of low grade results, the
procedure used for such aggregation should be stated and some
typical examples of such aggregations should be shown in
detail.
- The assumptions used for any reporting of metal equivalent
values should be clearly stated.
|
- Not reporting
exploration results.
- Not reporting
exploration results.
- No metal equivalent
grades have been used.
|
Relationship
between mineralisation widths and intercept
lengths
|
- These relationships are particularly important in the
reporting of Exploration Results.
- If the geometry of the mineralisation with respect to the
drill hole angle is known, its nature should be
reported.
- If it is not known and only the down hole lengths are
reported, there should be a clear statement to this effect (eg
'down hole length, true width not known').
|
- The Mabilo drill
have been drilled both vertically and inclined. The orientation of
the mineralised bodies is based on interpretation of geology from
drill holes supported by magnetic modelling which indicates that
much of the mineralisation is dipping to the southwest.
- The interpreted
orientation of the mineralised bodies is based on magnetic
modelling and drill-hole data and is documented in the report. The
fact that the intersections are in a dipping body and therefore not
true widths has been reported.
- No intervals
reported can be assumed to be a true width of the
mineralisation.
|
Diagrams
|
- Appropriate maps and
sections (with scales) and tabulations of intercepts should be
included for any significant discovery being reported These should
include, but not be limited to a plan view of drill hole collar
locations and appropriate sectional views.
|
- Refer to figures within the main body of this
report.
|
Balanced
reporting
|
- Where comprehensive
reporting of all Exploration Results is not practicable,
representative reporting of both low and high grades and/or widths
should be practiced to avoid misleading reporting of Exploration
Results.
|
|
Other
substantive exploration data
|
- Other exploration data, if
meaningful and material, should be reported including (but not
limited to): geological observations; geophysical survey results;
geochemical survey results; bulk samples – size and method of
treatment; metallurgical test results; bulk density, groundwater,
geotechnical and rock characteristics; potential deleterious or
contaminating substances.
|
- All meaningful
exploration data concerning the Mabilo Project has been reported in
previous reports to the ASX.
|
Further
work
|
- The nature and scale of planned further work (e.g. tests for
lateral extensions or depth extensions or large-scale step-out
drilling).
- Diagrams clearly highlighting the areas of possible
extensions, including the main geological interpretations and
future drilling areas, provided this information is not
commercially sensitive.
|
- Drilling is ongoing
at the Mabilo Project which will systematically test magnetic
bodies and step-out targets along strike and between the North
Mineralised Zone and the South Mineralised Zone as well as down-dip
from these zones.
- Refer to figures
within the main body of this report.
