Masuparia Drills 34.40 Metres Of 1.03 G/T Au Including 7.40 Metres Grading 2.82 G/T Au At Tenoriba, Mexico
June 25, 2008
Vancouver, British Columbia - Masuparia Gold Corp. (�Masuparia�) is pleased to announce gold assay results from the 2008 diamond drilling program on its Tenoriba property in southern Chihuahua State, northwest Mexico. From January to April, 2008 Minera Masuparia S.A. de C.V. completed a total of fifteen (15) diamond drill holes totaling 2566.90 metres, within the Do�a Lola, La Falda, West Adularia, East Adularia, Los Hilos and La Ceniza West areas.
The drill program was primarily designed to test for mineralization beneath geochemical anomalies in the more accessible parts of the project area. The following anomalies were tested: La Falda and Los Hilos (four holes each), La Ceniza West (three holes), East La Adularia (two holes), and on Do�a Lola and West La Adularia, (one hole each).
Due to difficult ground conditions, holes 1, 12, 13, 14 and 15 were abandoned before reaching their target depths.
All fifteen drill holes intersected anomalous gold values, often over wide intervals. Those reporting greater than 0.4 g/t over at least 0.5 metres are deemed significant and are summarized in Table 1 below. Drill collar locations, bearings and dips are detailed in Table 2. Some significant highlights are (all widths are drilled widths):
- Drill hole TDH-07 intersected 16.00 metres, from 35.0 to 51 metres, averaging 0.49 g/t Au (interval 1, Table 1) and intersected 3.70 metres, from 61 to 64.7 metres, averaging 5.33 g/t Au, including a 1.90 metre interval that assayed 45.90 g/t Au (interval 1ii) which was cut to 10 g/t Au for reporting above average calculations.
- Drill hole TDH-11 intersected 39.70 metres averaging 0.48 g/t Au (interval 2 Table 1), from 27.30 to 67.0 metres down hole, including 8.20 metres (interval 2i Table 1) averaging 1.45 g/t Au. Deeper downhole, 34.40 metres were intersected averaging 1.03 g/t Au ( interval 3 Table 1) beginning at 110 metres and including 7.40 metres averaging 2.82 g/t Au (interval 3i Table 1) and 9.40 metres averaging 1.37 g/t Au (interval 3ii Table 1). Starting at 161.00 metres, 4.00 metres averaging 1.24 g/t Au were intersected (interval 4 Table 1), and finally from 185.0 metres there were 13.80 metres averaging 0.60 g/t Au (interval 5 Table 1) which includes 1.40 metres averaging 3.64 g/t Au (interval 5i Table 1).
- Drill hole TDH-12 intersected 3.00 metres averaging 1.04 g/t Au from 54.80 metres downhole (interval 1 Table 1), and 2.00 metres averaging 1.43 g/t Au from 129.8 metres (interval 3 Table 1). The hole was abandoned at 131.8 metres still in mineralized rock ..
- Drill hole TDH-13 intersected 25.60 metres averaging 0.56 g/t Au from 21.0 metres downhole (interval 1 Table 1) .
- Drill hole TDH-14, drilled on the same setup as TDH-13, intersected 66.0 metres averaging 0.50 g/t Au (interval 1 Table 1) from 4.0 metres downhole, which includes a 16.50 metres intersection averaging 1.00 g/t Au starting at 9.00 metres downhole ( interval 1i Table 1).
- Drill hole TDH-15, drilled 80 metres north and 40 metres higher than TDH-11, intersected 12 metres averaging 0.64 g/t Au beginning at 50.00 metres downhole (interval 1 Table 1) , and 2.06 metres averaging 2.77 g/t Au from 110.80 metres downhole (interval 2 Table 1).

The Tenoriba property is within the Sierra Madre Occidental volcanic-intrusive province. It is characterized by the Lower Volcanic Super Group volcanic rocks, which are intruded by granodioritic stocks and are overlain by the Upper Volcanic Super Group consisting of rhyodacitic to rhyolitic ignimbrites and associated tuffs, and minor lava flows. Economically, the highest potential for the property appears to be the contact zone between the partially overlying Lower Volcanic Super Group rocks (to the west, north and south), and the porphyritic granodioritic to dioritic intrusive rocks (to the south) where a greater than 7 by 5 km, strong alteration zone hosting the gold mineralization occurs.
This drilling program confirmed that gold values are preferentially located within intensely hydrothermal-altered rhyolitic tuffs that belong to the Lower Volcanic Supergroup. Those rocks are strongly fractured and have strong argillic and silica alteration with abundant disseminated pyrite and minor later stage quartz veining and silicification. Higher Gold assays appear to be related to steeply dipping, silicified structural zones, with some dissemination into the country rock. The drilling confirmed a mineralized zone 600 by 150 metres wide tested area, which is open.
Core samples from the 2008 drill program were delivered from the drill into a secure core processing facility. Samples were prepared by splitting the core using a diamond saw, keeping one half of the core for reference purposes, doing sample preparing of one-half the sampled HQ core at Chemex preparation facilities in Chihuahua, Mexico, and assaying the pulp in Vancouver, BC. Assay results for gold were determined by fire assay. In addition to quality control by TSL Laboratories, Masuparia inserts Certified Reference Materials and blanks into sample batches for independent verification of quality control.
The technical material contained in this release has been reviewed and approved by Leopold J. Lindinger, P.Geo., Masuparia�s independent qualified person for the Tenoriba-Sucara project, under National Instrument 43-101 guidelines.
