OVERVIEW OF QUARTER

The December Quarter for the Mabilo Project was a significant one, with the reporting of a Maiden Resource Statement, materially improving both the understanding of the Project and the confidence in being able to move forward to a successful development. The definition of two high grade oxide mining products materially improves the economics of the Project and with limited need for upfront capital, potentially reduces future dilution from equity issues.

The results to date of Phase 1 scoping metallurgical test work have also allowed a better definition of the end products from the proposed primary plant, producing two high grade and clean products that will enable discussions with offtake parties to advance and create a highly competitive environment for negotiations.

MABILO 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 one Exploration Permit Application (EXPA-000188-V) of 2,820 ha. The Project area is relatively flat and is easily accessed by 15 km of allweather 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 calcsilicate 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 high-grade 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 ninety diamond drill holes have been completed at the end of the Quarter with further drilling ongoing.

Maiden Resource

Summary tables are attached in Appendix 4.

As per ASX release 24[th] November 2014

  • Total Mineral Resource of 11.4Mt at 1.8% Cu, 2.0g/t Au, 10.6g/t Ag and 44.2% Fe

  • Total Indicated Resource of 5.9Mt at 2.1% Cu, 2.2g/t Au, 8.4g/t Ag and

49% Fe, containing 121,000t copper and contained gold of 414,000oz at a 0.3g/t Au cut-off grade.

  • Total Inferred Resource of 5.5Mt at 1.5% Cu, 1.7g/t Au, 12.9g/t Ag and 39% Fe, containing 84,000t copper and contained gold of 302,000oz at a 0.3g/t Au cut-off grade.

  • Indicated Oxide Resource that includes a high grade oxide gold “cap” zone (340,000t @ 3.2g/t Au) and a very high grade Supergene Chalcocite zone (101,000t @ 24.0% Cu) at shallow depths. Both represent significant value with the mining of this product potentially able to assist in funding capital development of the larger primary plant.

South Body

Drilling focused on the South Mineralised Zone, in preparation of the maiden resource estimate, most drill holes were infill in nature to increase confidence in the central part of the system at the same RL as previously reported MDH-60, MDH-65 and MDH-67 (ASX release 13th August 2014). Drilling continued to validate the geology model, a number of spectacular infill intercepts returned are highlighted in Figure 3 and Table 1.

Drilling during the quarter was infill in nature and in good agreement with the geology model, infill drilling was consistent in style and quality of drilling previously reported for magnetite skarn in this part of the system. Drill hole locations are shown in (Figure 4) and a full list of drilling and outstanding drill holes awaiting assays during the quarter is reported in Appendix 1.

True widths for intercepts reported in Table 1 were determined by modelling as follows: MDH86 ~32m, MDH-80 ~20m, MDH-75 ~12m, MDH-89 ~29m.

* MDH-78 was designed to collect metallurgical samples and determine the position of east dipping structures. This hole drilled oblique to magnetite skarn, therefore no true width is determined and interval should be referred to as down hole interval only.

Oxide Gold

Three drill holes were designed to define the eastern limits of oxide mineralization of South A Zone of which a number of spectacular intercepts were the subject of reporting (ASX release on 20[th] November) and are summarized below. Oxide mineralisation intercepted in three drill holes is characterised by a gold rich copper depleted zone and an oxide copper zone which also contains significant gold mineralisation. The oxide gold zone included the highest grade assay received on the Mabilo Project with MDH-074 returning 0.60m @ 46.00 g/t Au from a downhole depth of 41.40 meters.

Oxidation of primary magnetite skarn is lateral in extent and penetrative vertically, all true thicknesses reported for oxide gold intercepts in this release are therefore considered vertical in nature and modelling is supportive of this. True thickness of the oxide gold zone in MDH-76 and MDH-81 is approximately 9 meters and 22 meters respectively. Drill hole MDH-74 intercepted significant oxide copper in addition to oxide gold, the combined true thickness for oxide gold & oxide copper zones was approximately 29 meters. Sections for MDH-74, MDH-76 and MDH-81 are listed below for reference.

Metallurgical Test Work Highlights

Lycopodium Minerals Pty Ltd has managed a Phase I (scoping level) metallurgical test work program with analysis undertaken at ALS Metallurgy in Perth, Australia. The program covered the oxide and primary domains with excellent results.

The primary skarn material composite showed excellent floatability with a standard reagent suite at a P80 grind size of 106µm. Key results from the primary test work include:

  • Concentrate grades up to 33% Cu and 20g/t Au;

  • Copper recovery up to 96%;

  • Overall gold recovery of up to 85% to concentrate and float tail leach; and

  • Ball Mill Work Index of 14 kWh/t.

Test work on the “Gold Cap” oxide material showed gold recoveries up to 90% with cyanide consumption of 3.5kg/t and lime consumption of 1 kg/t.

The Phase I program will be finalized Q1, 2015 and forms the basis for the definitive test work program and associated process design & engineering.

Feasibility Study

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

The Study remains on track for completion in the third quarter of the 2015 calendar year.

OTHER PROJECTS

The Bunawan Project is centered on a diatreme intrusive complex (Mahunoc diatreme) approximately five km NE of Medusa Mining’s Co-O mine in eastern Mindanao, Philippines. At Co-O high-grade Au bearing veins are developed perpendicular to the margin of a diatreme body (Co-O diatreme). At Bunawan a number of substantial artisanal mining operations occur within and adjacent to the Mahunoc diatreme. The edge of the diatreme is coincident with a 1.5km anomalous gold geochemical signature and the project is considered highly prospective for the discovery of economic epithermal Au-Ag mineralisation of intermediate sulphidation / carbonate-base metal type.

Following the granting of the Exploration Permit for Bunawan in August, the Company commenced a reconnaissance drilling program in November. At the end of the quarter nine holes had been completed for 3,074 metres. The results will be reported in the next quarter when assays are available.

CORPORATE

As at 31 December 2014, RTG had cash and liquid assets of US$5.73M (September quarter: US$8.59M). The quarter focused on finalising the maiden JORC Mineral Resource at Mabilo and the accompanying Technical report and commencement of the diamond drilling program at the highly prospective Bunawan Project.

Feasibility work at Mabilo continues with Phase 1 metallurgical test work due for completion at the end of January and given the successful results obtained during the preliminary test work, RTG intends to move immediately into Phase 2 Definitive Feasibility Study metallurgical test work upon the completion of Phase 1.

ensure representative nature of the samples. 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.

Mt Labo has entered into a joint venture agreement with Galeo Equipment and

Projects, down to 200 m below surface, by contributing approximately
US$4,250,000 of exploration drilling and management services for the Projects

In November 2013, Sierra Mining Limited (“Sierra”), a wholly owned subsidiary

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
