Valterra Lists on the TSX Venture Exchange

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 28, 2011) - Valterra Resource Corporation (TSX VENTURE:VQA)(CNSX:VTA)(FRANKFURT:3VA) ("Valterra") is pleased to announce that effective at the opening of market on June 28, 2011, Valterra's common shares were listed and commenced trading on the TSX Venture Exchange under the symbol "VQA". A listing application dated June 22, 2011 was prepared in accordance with the policies of the TSX Venture Exchange and is available under Valterra's profile on SEDAR at www.sedar.com. Effective at the close of trading on July 4, 2011, Valterra's common shares will be delisted from the Canadian National Stock Exchange.

Mineral Property Summaries

Valterra has been aggressively exploring south-eastern British Columbia since 2007, building key assets including the Au-Ag+/-Cu porphyry/shear-hosted "Star Project" (Star, Toughnut, and Rozan claims), and the Cu-Au porphyry/shear-hosted Swift Katie Project, all located near Salmo BC.

Valterra has conducted over 810 line-kilometres of airborne geophysical surveys and completed several mapping/diamond drilling programs totalling more than 9,250 metres. Numerous drill intercepts for Au, Ag, and Cu have been returned, and the prospective claim group controlled by Valterra has doubled to over 120 square kilometres.

Star Project

The Star project, which includes the Star, Toughnut, and Rozan group of claims is Valterra's flagship holding comprising almost 40 square kilometres centralized in the prolific Silver King Shear Zone. Valterra has completed 20 NQ2/BTW-sized drill holes (4,423m) and returned several encouraging intercepts for Au-Ag +/- Cu from five known zones aligned over a 3.5 kilometre strike length.

Select Valterra drill intercept highlights include:

The signature of the rocks intercepted in the past drilling are generally consistent with a zoned porphyry model subjected to shortening and intense shear-fault/hydrothermal activity that generated focused zones of higher-grade mineralization. Targeting has been aided by several technical programs implemented by Valterra that included a technical report titled NI 43-101 Technical Report, Compilation Report on the Star-Toughnut Property, Nelson Mining Division, British Columbia, Canada, March 10, 2011. The report supported Valterra's listing application and is filed on SEDAR.

Additionally, a 30 square kilometre airborne EM-MAG survey was completed in 2010. The resultant data, together with historical ground geophysical surveys were subjected to detailed processing analyses by consultants whose work refined and sharpened numerous anomalies warranting follow-up.

Swift Katie Project

The Swift Katie group of claims comprises more than 80 square kilometres located near Salmo BC and centralized in an infrastructure-rich region of the province. Valterra has completed 15 drill holes (4,866m) and returned several encouraging intercepts for bulk-tonnage Cu-Au from the Main Katie zone; being underlain by prospective volcano-sedimentary rocks assigned to the Rossland Group which hosts numerous precious-metal and polymetallic past-producers in this prolific belt.

Select Valterra drill intercepts from the 2007-08 Katie zone include:

* Gold equivalencies (g/t) are calculated using US$950/oz gold, US$2.50/lb copper and the formula: (%Cu x 22 x Price Cu/lb) + (g/t Au x 0.029 x Price Au/oz) / (Price Au/oz x 0.029).

Initially, the Swift Katie was Valterra's qualifying property, and a NI 43-101 report dated July 2007 was authored by Price and Makepeace (available for viewing at www.sedar.com). Valterra owns a 60% interest in the Swift Katie and expects to increase such interest in 2011 to 100% by issuance of 225,000 shares and payment of C$60,000 as the residual consideration to fully exercise the option.

2011 Exploration Proposal for Valterra in Southeast BC

  • STAR - Phase I drilling and surface exploration is expected to begin immediately at the Star Project. Valterra has budgeted C$300,000 toward testing four high priority zones; the Eureka, the Alma-Star Link, the Alma N, and the Gold Eagle. Up to 1,300 metres of diamond drilling is anticipated within the 3.5 kilometres of strike length currently defined by a combination of previous wide-spaced drilling, geochemical, and geophysical surveys. Furthermore, advanced studies on the vast project database have identified 'embayments' in the geophysics coincident with geological contact zones and strong hydrothermally altered units. To date, the Au-Ag signature is often elevated when these features are core sampled, yet the structures are only nominally tested in the drill record. In 2011, two large embayment features are earmarked for drill testing.
  • SWIFT KATIE - Valterra has retained Micon International Limited of Vancouver to conduct a Phase I, in-house review of the current database for the Katie deposit which comprises over 45 drill holes, completed between 1987 and 2008. The drilling outlines a Cu-Au inventory measuring approximately 600 metres of strike length by 400 metres width, and up to 300 metres depth; being open in several directions. The Phase I work will include surveying of historic drill collars, an assessment of the historic QA/QC protocols, and drill spacing. Contingent on the Phase I results, the Phase II proposal includes provisions for developing a NI 43-101 compliant bulk-tonnage Cu-Au resource.
