Lago Dourado Provides Exploration Update On Its Juruena Project, Brazil

TORONTO, ONTARIO--(Marketwired - May 29, 2013) - Lago Dourado Minerals Ltd. (TSX VENTURE:LDM), (the "Company") has received assay results for an additional three diamond drill holes at the Arrastro Hills porphyry target at its flagship 100%-owned Juruena Project located in Mato Grosso, Brazil. Holes JRND066 and JRND067, drilled in the central part of Arrastro Hills, and hole JRND068 (results have been received for the top 200m of this hole), the first hole drilled at the Arrastro Hills South East target, did not intercept any significant gold mineralization. Assay results for the remaining two holes drilled at Arrastro Hills South East (JRND069 and JRND070) are still pending. However, based on these initial drill results and the visual core inspection of these remaining holes, it would suggest that the alteration minerals and assemblages at Arrastro Hills and Arrastro Hills South East are a result of an intrusive heat source that is distal to or non-related to an underlying mineralized porphyry body.

The Arrastro Hills Complex was identified as a potential mineralized porphyry target based on the extensive clay-silica alteration, multi-element zonation, alteration signature, variable intrusive rock types and magnetic and radiometric characteristics. In total six reconnaissance-style diamond drill holes were completed within the Arrastro Hills complex (see Figure A). The first three holes (JRND065, JRND066 and JRND067) targeted soil values anomalous with elements associated with the possible epithermal leakage in the central part of the hills. The second three holes (JRND068, JRND069 and JRND070) were drilled in the southeastern part of the hills to test an Au-Cu soil anomaly, strongly brecciated and silicified volcanic rocks, interpreted magnetic heat source, and a strong high temperature muscovite alteration signature identified from SWIR analysis. The six drill holes intersected acid altered silicic volcanic rocks including multiple zones containing dykes and breccia intervals, finely disseminated sulfides and sulfide-filled fractures and vein. However, the lack of gold mineralization and associated porphyry-related elements in the assays received to date downgrade the probability of intersecting a mineralized porphyry at a shallow to intermediate depth at the Arrastro Hills Complex. Based on these results, the Company will shift its focus back to the multiple high-grade gold zones previously discovered in the central part of Juruena.

Future Plans

Drilling at the project has been halted and exploration work will now focus on advancing the known mineralized zones in the central part of Juruena in a cost effective manner. Previous drilling from the central area of the project has identified seven distinct mineralized zones with more than 20 intercepts with greater than 50 gram-metres gold (see Figure B). The two high priority zones the Company will initially focus on are the high-grade mineralized zones of Querosene and Donna Maria.

Querosene is a high-grade structure with more than 400 metres strike length that has returned intervals of 4m @ 32.5 g/t Au and 2m @ 47.1 g/t Au. Only eight shallow (less than 200m) diamond holes have been drilled at this zone. Donna Maria is a high-grade structure adjacent to the Crentes Zone. Historic drilling at Donna Maria returned 5.8m @ 52.4 g/t Au and 10.5m @ 14.6 g/t. The Company has drilled only one diamond drill hole at Donna Maria which returned two intervals of 1.0m @ 101.1 g/t Au and 16.0m @ 2.1g/t Au. Given the structural control of both these zones, ground magnetics will likely be a useful and cost-effective exploration tool to gain a clearer understanding of the underlying structures that host the gold mineralization.

The Company also plans to advance the Novo Astro target to a drill ready status. Novo Astro is host to an extensive set of active artisanal workings located approximately 25km east-south-east along trend from Juruena. Detailed geological mapping and extensive soil sampling of the area suggests that Novo Astro, whilst related to intrusive activity, exhibits more classical lode-style controls to mineralization. It is a gold-rich structurally-controlled system containing distinct high-grade gold zones that have good strike continuity. The main gold-in-soil anomaly is approximately 1 km wide and more than 2 km in strike length. Rock chip samples have returned very high gold numbers, including 92.9 g/t Au, 34.5 g/t Au and 18.2g/t Au. In-fill soil sampling has been completed over the higher priority areas identified during the recently completed geological mapping work (assay results are pending). Once all the assays have been received and have been integrated into the current dataset, any further follow up work will be determined before specific drill ready targets can be identified for future testing.
