ANNOUNCEMENT FOR THE TORONTO STOCK
EXCHANGE AND AUSTRALIAN SECURITIES EXCHANGE
SUBIACO, Western
Australia, April 14, 2015 /CNW/ - The Board of RTG Mining
Inc. ("RTG", "the Company") (TSX Code: RTG, ASX Code:
RTG) is pleased to announce significant high grade gold and
copper intercepts in the South Mineralized Zone at the Mabilo
Project in the Philippines.
Resource drilling on the South Body designed to upgrade resource
classification has successfully intersected further mineralisation
at the southern end of the South Body. The drilling has confirmed
the down dip extent of the high grade garnet skarn mineralisation
intersected in drill hole MDH-95 (RTG reported ASX 26th
February 2015). Additional Magnetite
Skarn mineralization currently outside the resource model was also
intersected in MDH-096, with 35m @ 1.86 g/t Au and 1.29 %
Cu confirming the continuation up-dip of the magnetite skarn.
The mineralisation remains open down dip and along strike in both
directions, with all mineralisation found to date being shallow
enough to be amenable to open pit mining techniques.
Highlights of the ongoing drilling program include –
- MDH-096 interval confirming the up-dip continuation of
magnetite skarn at shallow level positions in this part of the
system.
35 meters @ 1.86g/t Au and 1.29% Cu from 156.00 meters
downhole.
- MDH-094 is a South-West extension of the magnetite skarn.
43.20 meters @ 1.09g/t Au and 1.01% Cu from 242.00 meters
downhole.
- MDH-94 confirmed continuity of garnet skarn at depth with two
intercepts including one with significant gold mineralisation.
6.00 meters @ 2.54 g/t Au and 1.04% Cu from 175.00 meters
downhole.
The two drill holes reported MDH-94 and MDH-96, together with
previously reported in MDH-95, extend the intersected strike length
of mineralisation by 40m.
Significantly, the section identified Garnet Skarn
mineralisation not previously intercepted and confirmed additional
down-dip Magnetite skarn mineralisation beyond the previous
resource model (RTG ASX release 24th November
2014).
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 upgrading the
resource classification (RTG ASX release 24th
November 2014) over the South Body
and North Body.
MDH-096
MDH-096 was designed as a follow-up hole to the successful
MDH-095 (RTG ASX release on 26th February 2015). Targeting the up-dip continuation
of the Magnetite and Garnet skarn, MDH-096 was successful in
intersecting Garnet and Magnetite, with magnetite recording
significant mineralisation. Strongly oxidised garnet skarn was
observed to be weakly mineralised in this position as a result of
strong oxidation and depletion within the interval (Figure 3).
Down-dip continuation of mineralised Garnet skarn in MDH-094
successfully demonstrated continuity at depth.
MDH-096 was successful in targeting mineralisation outside the
previously modelled magnetite with a modelled thickness being
approximately 23m.

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 ore 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.
|
Exploration
done by other parties
|
- 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.
