RTG ANNOUNCES FURTHER HIGH GRADE INTERCEPTS AND EXTENSIONS TO KNOWN MINERALISATION AT THE MABILO PROJECT

ANNOUNCEMENT TO THE TORONTO STOCK EXCHANGE AND AUSTRALIAN SECURITIES EXCHANGE

9 OCTOBER 2014

The Board of RTG Mining Inc. (“RTG”, “the Company”) ( TSX Code: RTG , ASX Code: RTG ) is pleased to announce further high grade copper, gold and iron intercepts in both the North and South Mineralized Zones at the Mabilo Project in the Philippines.

Drilling targeted at extending the South Mineralised Zone to the North, has intersected further high grade supergene copper mineralisation. With a massive chalcocite intercept of 19.10 meters for 26.16% Copper & 2.18 g/t Au .

Further diamond drilling has continued to extend down dip extension of the South Mineralised Zone with further high grade intercepts. The system continues to remains open at depth.

Highlights of the ongoing drilling program include –

  • MDH-073 intersected a chalcocite zone below a significant gold oxide zone.

16.65 meters at 4.45 g/t Au, 0.38%Cu and 44.3%Fe Approximately 6.13g/t Au Equivalent and 19.10 meters at 2.18g/t Au, 26.16% Cu and 28.4% Fe Approximately 47.65g/t Au Equivalent

  • MDH-071 continued to extend mineralisation on the same section as MDH066.

35m meters at 2.79g/t Au, 4.47% Cu and 32.54% Fe Approximately 11.37g/t Au Equivalent

  • MDH-067 continued to define the down dip and true width of primary magnetite mineralisation.

23 meters at 2.30 g/t Au, 1.76% Cu and 47.43% Fe Approximately 6.46g/t Au Equivalent including 9 meters at 4.12g/t Au, 3.24% Cu and 57.82% Fe Approximately 11.07g/t Au Equivalent

Work on the maiden resource for Mabilo is well underway. The resource will include seventy eight diamond drill holes and remains on track to be released in early November 2014.

Gold Equivalent grade calculations included in this release have been based on assumed commodity prices of US$1220/oz Au, US$6700/t Cu, US$17/oz Ag and US$90/t Fe and the following formula - (((GoldGrade(1220/31.103486))+((CopperGrade/100)6700)+((SilverGrade(17/31.103486))+((IronGrade/100)90)))/ (1220/31.103486)).

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 defining the SW down dip extent of the South Mineralised Zone and is targeting the oxide and supergene potential to the North of the South Mineralised Zone.

MDH-067

An angled hole drilled to test the down dip extent and true thickness intersected in MDH040 reported previously (ASX release by Sierra Mining 3rd April 2014). The hole intersected magnetite skarn from 138.00 meters to 178.40 meters with higher grade intervals characterised by well-developed chalcopyrite inter-grown with magnetite weakly overprinted by silica pyrite (Figure 3). True thickness of the magnetite skarn is approximately 32 meters.

MDH-071

Located 20 meters North East of MDH-066, MDH-071 is an angled hole drilled to further test the continuity of oxide and chalcocite mineralisation intersected in MDH066 (Figure 4). The drill hole intersected oxidised supergene zone 31.00 meters to 59.30 meters with massive chalcocite supergene from 59.30 meters to 63.00 meters. True thickness of the magnetite skarn is approximately 30 meters.

MDH-073

An angled hole designed as an incremental 20m step North West of previously drilled MDH066 reported on (ASX release by RTG Mining 13[th] August 2014). Located 23 meters North East of MDH-029 at the Northern limit of the magnetic model (Figure 2). The drill hole (Figure 5) intersected an oxide zone from the Labo Volcanics overburden at 38.95 meters to 55.60 meters followed by a massive chalcocite zone from 61.90 meters to 81.00m meters with a bleach clay zone separating the two intervals. The bottom of the interval is garnet skarn from 106.00 meters 111.00 meters characterised by massive chalcopyrite garnet and magnetite veinlets. True combined thickness of the oxide mineralisation and chalcocite zone is approximately 48m.

CAUTIONARY NOTE REGARDING FORWARD LOOKING STATEMENTS

This announcement includes certain “forward-looking statements” within the meaning of Canadian securities legislation. Accuracy of mineral resource and mineral reserve estimates and related assumptions and inherent operating risks, are forward-looking statements. Forward-looking statements involve various risks and uncertainties and are based on certain factors and assumptions. There can be no assurance that such statements will prove to be accurate, and actual results and future events could differ materially from those anticipated in such statements. Important factors that could cause actual results to differ materially from RTG’s expectations include uncertainties related to fluctuations in gold and other commodity prices and currency exchange rates; uncertainties relating to interpretation of drill results and the geology, continuity and grade of mineral deposits; uncertainty of estimates of capital and operating costs, recovery rates, production estimates and estimated economic return; the need for cooperation of government agencies in the development of RTG’s mineral

projects; the need to obtain additional financing to develop RTG’s mineral projects; the possibility of delay in development programs or in construction projects and uncertainty of meeting anticipated program milestones for RTG’s mineral projects and other risks and uncertainties disclosed under the heading “Risk Factors” in RTG’s Annual Information Form for the year ended 31 December 2013 filed with the Canadian securities regulatory authorities on the SEDAR website at sedar.com.

the records
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.
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.
Criteria JORC Code explanation Commentary
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.
