Parlozi Exploration Permit

Highlights

  • High grade silver mineralization associated with lead and zinc sulphides: comparable to Trepca type, and Mexico - Peru cordilleran skarn/manto deposits.
  • Extensive areas of historical surface silver mining, and limited to shallow depths by water table.
  • Previous exploration by Former Yugoslav government agencies in 1960 – 1990 period (including exploration adits and drilling) focused on base metal resources – precious metals often not analysed.
  • Former Yugoslav (not 43-101 compliant) historical resource estimate: 6.5 Mt @ 4.1% Pb, 2.1% Zn, 0.3% Cu and 130 g/t Ag.
  • Reservoir's validation drilling identifies high silver (max 1175 g/t Ag, with 7.8 m @ 214 g/t Ag and 11.5 m @ 102 g/t Ag) and gold (2.81 g/t over 6.15 meters) contents, and confirms base-metal grades.
  • Excellent potential for enhancing resource tonnage and silver content.
  • 43-101 Technical report issued 17July 2011.

Title and Area

The Parlozi (Kosmaj-Babé ) Exploration Permit is held by Balkan Exploration and Mining (BEM d.o.o.) a 100% owned Serbian subsidiary of Reservoir Minerals and covers an area of approximately 91 sq. km. The Permit is easily accessible by road being approximately 40 km south of Belgrade.

Mining and Exploration History

The Parlozi Permit contains abundant evidence of Roman mining and smelting activity, with large dumps of smelter slags that were presumably produced as a result of the extraction of silver from the sulphide ores. Historical exploitation was limited by the water table to an estimated depth of about 150 meters below surface.

There was a brief resumption of mining and exploration activities between 1889 and the beginning of the 2nd World War, including the opening of 14 adits and levels, and 4 shallow shafts. Exploitation was limited to high grade mining in the areas of previous Roman working.

Exploration of the Parlozi prospect by Former Yugoslav government agencies commenced in the 1960’s and continued to 1990. Exploration included 36 diamond drill holes (15,105 meters total), surface geological mapping, geochemistry and geophysics (airborne magnetometry and radiometrics, ground IP).The exploration was directed primarily at defining zinc-lead resources for the Trepca smelter and refinery located at Mitrovice. There is a remarkable lack of data pertaining to precious metals – particularly gold.

The Company has acquired much of the documentation pertaining to the last phase of exploration and this data is being compiled into a 3D database and the mineralization outlines have been modeled using Datamine software.

Historical Resources

The Parlozi (also known as Kosmaj-Babé) deposit is listed in the Mining Districts of Serbia, District Database (Ministry of Mining and Energy) with an historical resource of 6.5 Mt @ 4.1% Pb, 2.1% Zn, 0.3% Cu and 130 g/t Ag. The historical resources were calculated according to the Yugoslav resource criteria (similar to the Soviet classification) from 11 drill holes along a 700 meter strike length. These historical resources are not compliant with National Instrument 43-101 guidelines and should not be relied on, but the Company considers that they are relevant to the assessment of the Parlozi Project.

Geology and Mineralization

The project area lies within the Vardar Zoneof Neogene carbonate-replacement and epithermal Pb-Zn-Ag and porphyry Cu mineralization. The Ag-Pb-Zn mineralization occurs within the Šumadija metallogenic district, and bears many similarities with the mineralization in the famous Kopaonik district (Trepca mines).

The Parlozi mineralization is hosted in shallowly dipping Upper Cretaceous siltstones, marls and limestones, intruded by Neogene rhyolitic to quartz latite dykes and sills up to 5 metres wide. Alteration comprises chlorite-epidote alteration of marl and limestone units distal to intrusive rocks silica flooding of siltstone proximal to intrusive rocks, and silica flooding of intrusive rocks with moderate, fine-grained, disseminated pyrite and arsenopyrite is observed.

The mineralization occurs as veins and stratabound replacement of the Cretaceous carbonates and is spatially associated with intrusive Neogene quartz-latite dykes and dacitic volcanic breccias, which are intensely argillised and pyritized near the mineralization. The mineralization proximal to the breccias is enriched in gold, and marked by arsenopyrite and intense silicification of the host marls and limestones. Lead and zinc sulphides together with pyrite occur distally from the intrusive contact, but are also associated with intense silicification of the host carbonates. The ore mineralogy includes argentiferous galena, sphalerite and pyrite with accessory chalcopyrite, arsenopyrite, tetrahedrite, marcasite and gold.

Historical drilling indicates that the Parlozi mineralization forms a zone which strikes north over >300 metres and occurs between 200 and 500 meters below surface. Mineralization comprises more than five individual, moderately to steeply west-dipping, sub-parallel massive sulphide zones. Individual sulphide zones are between 50 centimeters and 2 meters thick, displaying a tabular, locally discontinuous morphology.

Observations from drill core indicate that the sulphide zones occur as both strata-bound-mantos and as discordant, massive sulphide filling sub-vertical fault zones. Mantos are recognized by disseminated and blebby sulphide replacing limestone, marl and volcaniclastic units. Mineralized fault zones are recognised in drill core by strong fracturing of the host rock adjacent to massive sulphide, with weak disseminated sulphide and chlorite-epidote alteration of the wall rock. Massive sulphide hosted in fault zones is commonly fractured and crosscut by chlorite veinlets and later quartz-carbonate veinlets.

Some of the better intersections reported from the historical drilling included BK-14: 15.1 m @ 8.96% Pb, 1.2% Zn and 317 g/t Ag and 17.1 m @ 8.68 % Pb, 0.96% Zn and 250 g/t Ag.

Close to Parlozi, there are is an historical adit and shaft near Plandiste that were used to explore and exploit the mineralization beneath an area marked on the surface by intense ancient mining activity (pits and trenches).

This type of mineralization has long supported zinc-lead-silver mining operations at Trepca and other mines in Serbia and the western Balkan countries. However, the lead-zinc sulphide replacement mineralization at Parlozi is markedly enriched in silver (see table and images), which occurs at concentrations otherwise seen in the famous manto or carbonate-replacement-deposit (CRD) deposits in Mexico and Peru.

In addition to the Parlozi target, there are additional known mineralized occurrences at Ljuta Strana, Stenicka – Svinjcine, Gomilice, Grivacevac - Celevac, Kriva Zlatara and Glavcine. Systematic work was only undertaken at Parlozi.

Exploration Status

The Company has compiled and digitized much of the historical data, and completed a validation drill hole in the Parlozi area. The PA-1 validation drill hole was collared about 35 meters from historic drill hole BK-14,on the section that includes the earlier holes BK-6, 14, 17, 10 and 11. The hole was drilled to a depth of 600 meters on azimuth 110°.

The analytical results from PA-1 confirm the occurrence and location of mineralized intersections outlined by the historic drilling, some of the significant mineralized intersections are detailed in the table below.

The historic drilling data has been digitized into a 3D model using Datamine software, the 3D mineralization models support the historic model of mineralization, and are being used to target further exploration and drilling.

Surface mapping and sampling has identified areas of historic surface mining. Further studies are being undertaken to determine if surface mineralization is related to mineralization encountered at depth by historic exploration drilling. If surface mineralization is found to be an extension of mineralization already identified by drilling at depth, the potential extent of mineralization at the Parlozi Prospect will be significantly increased.

Ljute Strane

The Ljute Strane location is considered to be a potential Ag – Au epithermal target (surface sampling yielded 3 samples with >100 g/t Ag), possibly a high-level equivalent to that at Parlozi Prospect.

The Company has documentation pertaining to earlier underground exploration, but the analytical results are restricted to the base metals, silver analysis was not undertaken but is suspected to be a present associated with the base metal mineralization.

Notes on Historical resource estimate.

This historical resource estimate was not estimated under the guidance of CIM NI43-101. This historical resource estimate does not meet the CIM definition standard since the estimate has been classified using a foreign code which does not comply with NI43-101. The historical resource estimate should not be relied upon. The historical resource estimate is considered relevant as a guide to future exploration and is included for reference purposes only. The historical resource estimate does not use the categories set out in sections 1.2 and 1.3 of NI43-101. The historical resource estimate does not include any more recent estimates or data.

In order to verify and/or upgrade the historical resource estimate as current mineral resources or mineral reserves, further drilling is required. Given that only two sections contain more than one drill hole and that historic drill core is not available, further drilling is required to determine the orientation of and structural controls on mineralisation. This work would include twinning historic drill holes, additional infill drilling, and resource estimation using modern interpolation methods to conform to CIM standards.

A qualified person has not done sufficient work to classify the historical resource estimate as current mineral resources or mineral reserves.

RMI is not treating the historical resource estimate as current mineral resources or mineral reserves.
