Company Presentation Hot Rock is an ASX listed company focused on geothermal resource exploration and development in commercially attractive countries with growing energy markets. Strategically, the company is focusing on commercially proven volcanic geothermal systems and developing its extensive portfolio in Chile and Peru complimented with Hot Sedimentary Aquifer prospects in Australia. The Company is currently focused on its volcanic projects in South America which have the highest near term potential for creating value. In February 2012 the company executed joint venture agreements which have enabled EDC to become the majority partner in Hot Rock’s Quellaapacheta and Chocopata projects in Peru. After significant due diligence EDC is now proceeding with the JV at these two projects. This joint venture is a major milestone given EDC’s significant operating expertise and success in developing geothermal assets from discovery through to sale of power, over a time frame of 35 years. EDC intends to commence detailed field work programs in the next few months at Quellaapacheta and Chocopata, including geological, geochemical and magneto-telluric (MT) geophysical surveys. Hot Rock’s Asset Portfolio – Chile – South America: Hot Rock’s wholly owned subsidiary Hot Rock Chile SA holds thirteen granted geothermal exploration concessions covering 7 projects. All of these tenements remain 100% Hot Rock owned. The Chile Ministry of Energy has approved the applications to extend two exploration concessions for a further two years at the 100% held at Calerias and Longavi projects. Applications to renew two further exploration concessions at the Longavi project have been recently submitted. A reconnaissance field investigation program has been completed at HRL’s Santa Macarena project. – Peru – South America: Hot Rock’s wholly owned subsidiary Hot Rock Peru SA has filed applications for exploration authorizations at ten volcanic geothermal projects in Peru. Four of these have been granted to HRP of which two are included in the JV with EDC. Preliminary resource evaluation reports have been completed by HRL for the Quellaapacheta, Chocopata, Turu and Rupha projects. Also, HRL’s applications for a further five high quality geothermal exploration authorizations remain in process. – Otway Basin – Victoria, Australia: HRL’s five HSA tenements

  • Tracing a Major Crustal Domain Boundary Based on the Geochemistry of Minor Volcanic Centres in Southern Peru
    7th International Symposium on Andean Geodynamics (ISAG 2008, Nice), Extended Abstracts: 298-301 Tracing a major crustal domain boundary based on the geochemistry of minor volcanic centres in southern Peru Mirian Mamani1, Gerhard Wörner2, & Jean-Claude Thouret3 1 Georg-August University, Goldschmidstr. 1, 37077 Göttingen, Germany ([email protected], [email protected]) 2 Université Blaise Pascal, Clermont Ferrand, France ([email protected]) KEYWORDS : minor volcanic centres, crust, tectonic erosion, Central Andes, isotopes Introduction Geochemical studies of Tertiary to Recent magmatism in the Central Volcanic Zone have mainly focused on large stratovolcanoes. This is because mafic minor volcanic centres and related flows that formed during a single eruption are relatively rare and occur in locally clusters (e.g. Andagua/Humbo fields in S. Peru, Delacour et al., 2007; Negrillar field in N. Chile, Deruelle 1982) or in the back arc region (Davidson and de Silva, 1992). These studies showed that the "monogenetic" lavas are high-K calc-alkaline and their major, trace, and rare elements, as well as Sr-, Nd- and Pb- isotopes data display a range comparable to those of the Central Volcanic Zone composite volcanoes (Delacour et al., 2007). It has been argued that the eruptive products of these minor centers bypass the large magma chamber systems below Andean stratovolcanoes and thus may represent magmas that were derived from a deeper level in the crust (Davidson and de Silva, 1992; Ruprecht and Wörner, 2007). This study represents a continuation of our work to understand the regional variation in erupted magma composition in the Central Andes (Mamani et al., 2008; Wörner et al., 1992).

  • Geothermal Resources in Peru
    GEOTHERMAL RESOURCES IN PERU Ing. Guillermo Diaz Huaina Catedrático Universidad Nacional Mayor de San Marcos Universidad Nacional de Ingeniería Consultor en Geotermia Address: Prlg. Andahuaylas 984-dpto.158 La Victoria - Lima ( [email protected]) Starting from the unforeseen increasing of oil price that took place in 1973, a favorable attitude at international level toward the examination of an eventual substitution of this fuel was taken regarding the exploitation of other alternating and Renewable Energetic Sources as the GEOTHERM, a present resource existing in Peru. In fact , the Peruvian territory is part of the Pacific Fire Circle, Characterized by the occurrence of seismic movements, tectonic phenomena, a high concentration of geothermal caloric flow and the presence of vast volcanic rock deposits, some of them of recent age that make evident a latent magmatic activity. More than 400 thermal water manifestations between 40 – 89°C, had been identified at Peruvian territory, situated preferently along the Occidental Cordillera, and in less proportion at inland valleys and Oriental zone.(Fig N°1). This has permitted the determination of six (06) Geothermal Regions (Fig N° 2) GEOTHERMAL REGION SOUTH The recogniton research made at V REGION, Volcanic range, has permitted to establish geothermal areas of interest with the denomination of GEOTHERMAL FIELDS. A) FIELD TUTUPACA – CALACOA GEOTHERMAL The TUTUPACA – CALACOA geothermal field is also located on the southern part of Peru.. Calacoa area is at the inlands of Moquegua, and TUTUPACA is on Tacna and a portion of Moquegua (Fig N° 3). THERMAL MANIFESTATIONS In Calacoa area, the thermal manifestations are mainly associated with the Quaternary Volcanism, and they are shown as flows, fumaroles and geysers (Photo N° 1).

In Calacoa there are mainly volcanic rocks that have been deposited over a sedimentary Cretaceous basement. The geochemical interpretation of the results shows that thermal waters are an alkaline-chloride-sulphate water type. The Cl-SO4-HCO3 diagram shows that most of the geothermal waters plot close to the mature water portion, which is typical of geothermal deep fluids. High B concentrations lead to a relatively high B/Cl ratios as shown on a B-Cl binary diagram. This can be used to elucidate the reactions of waters with sedimentary marine rocks at deep depths. The δ18O vs δD plot indicates that the geothermal water originates by a mixing of meteoric water with magmatic water. The results for chemical geothermometry allowed us to estimate temperatures between 170 and 230 °C at the depth of the geothermal resources. ©© 2013 2012 The The Authors. Authors.

Las técnicas de análisis sísmicos comprendieron la utilización del espectro de frecuencias, correlación cruzada, localización sísmica, mecanismos focales y distribución de la frecuencia-magnitud. Se han registrado cuatro tipos de señales sísmicas: Volcano- Tectónico (VT), Largo Periodo (LP), tremores (TRE) y eventos producidos por la dinámica del glaciar o DG. En total, se han identificado aproximadamente 6500 sismos volcánicos, de los cuales más del 77 % corresponden a sismos de tipo VT que estarían asociados a procesos de ruptura de rocas que ocurren al interior del macizo volcánico, 18 % son señales de tipo LP y tremores, eventos que estarían relacionados con la dinámica de fluidos volcánicos al interior del volcán. El 5 % de los eventos fueron caracterizados como señales de tipo DG, ligados a la dinámica del glaciar (deshielo, etc.). La localización sísmica de los eventos de tipo Volcano-Tectónico ha permitido reconocer dos focos activos distribuidos en dirección oeste y noroeste, a 6 km y 15 km del volcán Coropuna, respectivamente.
