Pulacayo 1 000 t/d Phase I Feasibility Study - NI 43-101 Technical Report 090644-3-0000-20-IFI-100 used the Environmental Quality Standard for Soil Resources and Criteria for Contaminated Soil Remediation of the Republic of Ecuador. The sample with the highest number of non-standard parameters, was obtained in the ELBA of the dry season from an area of land in the area called Tajo, where there is the presence of mining environmental threats in the area of sampling and also in the surrounding ones, that coupled with the action of climatic factors (mainly rain and wind), generated pollution due to dragging of material. The parameters that are beyond the norm, recurrent in all samples and in all studies are arsenic, zinc, lead and cadmium. 20.3.4 Sediment Quality To evaluate the quality of sediments in the area of the Pulacayo Mining Project, 7 sampling points were collected for studies of dry season and wet season respectively. To compare with the reference values, Medmin used the Canadian Sediment Guidelines for the Protection of Aquatic Life, because Bolivia does not have its own regulations. The sample with the highest number of parameters beyond the Canadian standard is the one taken from the Huanchaca River, with a total of 5 exceeding parameters. This situation is mainly due to the presence of mining environmental threats in the sampling area and surrounding areas, which together with the action of climatic factors (mainly rain and wind) generated pollution thereof due to entrainment of material in the basin of the river aforesaid. The parameters that are beyond the norm, more recurrent in all samples, in all studies, are Arsenic, Lead, Zinc and Cadmium. 20.3.5 Drinking Water Quality (Drinking Water Distribution System) The Pulacayo mining center uses surface water from different sources, such as the snow thaws of the Cosuño mountain, the streams of Huayllas and Juskuni, these water sources are stored in the dam Yanapollera, Huayllas pond and Juskuni pond respectively. The distribution of water in the town of Pulacayo is made by plumbing and is done directly from the source. To study the quality of drinking water two sample collection campaigns were made, one in the dry season and one in the wet season, in order to evaluate and compare the data and get a better interpretation of the results and variations throughout the year. The results of quality of drinking water shows that the water quality is good in the ponds Huayllas and Juskuni throughout the year, the latter being the best quality. The water quality of the Yanapollera dam is low during the wet season; however, during the dry season this water improves its quality but still presents contamination by whole coliforms contamination, reducing its concentration relative to the sample obtained in wet season. 20.3.6 Condition of Flora and Fauna The Pulacayo Mining Project is not within any protected areas of Bolivia. The characterization of eco-biological components according to the classification by eco-regions and sub-Eco regions (Ibisch et al. 2003), indicates that the project area lies within two major sub-Eco regions: TWP Sudamérica S.A.

Pulacayo 1 000 t/d Phase I Feasibility Study - NI 43-101 Technical Report 090644-3-0000-20-IFI-100 The semi-arid Puna The Puna desert (semi-arid) in the Andean region. Moreover, its correlation with the classification of Navarro (2002), places the project in the Puna- Peruvian province, bio-geographical Chichas district. These are areas where the ombroclimate is dry; the dominant vegetation consists of xeric shrub lands. With six sets of vegetation ranging from Tholar-grassland, high-Andean to Tolillar semiarid of the Altiplano. 20.3.6.1 Flora Within the two characterized sub-eco regions are different types of vegetation, where the most representative are: a) Tarapacana Polylepis thickets (keñua) related to compact Azorella (yareta) b) Distichia cushions muscoides-Werneria pygmaea (cienegos) in the wetlands c) Cristatum Tetraglochin thorny scrub, Adesmia spinosissima and Adesmia sp. d) Low shrubs of Baccharis boliviensis (pescollanta) and Fabiana densa (tarallanta) e) Lampaya castellani Scrub (Lampaya) f) Trollii Oreocereus Scrub (branched cactus). g) Orthophylla Festuca grasslands (ichu) h) Leptostachya Stipa Grasslands (sicuya) and scrub Parastrephia lucida (yakullanta). i) Secondary vegetation (in environmental threats). j) Secondary vegetation (ex-crops) Within the study area there have been recorded two families with two endangered species in different categories being the most threatened the Polylepis tarapacana "keñua" (Rosaceae) (see Chart 20.2). On the other hand, there have been four cactus species that are regulated under Appendix II of CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora). There are no endemic species.
