Trevali Announces Approval of Shareholders Rights Plan

 Vancouver, British Columbia... Trevali Resources Corp. ("Trevali" or the "Company") (CNSX: TV, Frankfurt: 4TI, Pink Sheets: TREVF) is pleased to announce that at its Annual General Meeting held on May 27, 2010, its shareholders overwhelmingly approved all resolutions including the shareholders rights plan that was adopted by the Company's board of Directors on April 22, 2010. The plan was supported by 100 percent of the votes cast by shareholders in person and by proxy.

The rights plan was adopted to ensure the fair treatment of shareholders in connection with any takeover bid for common shares of the Company. The rights plan was not adopted in response to any proposal to acquire control of the Company. The rights plan will expire at the end of the third annual general meeting of the Company's shareholders following this approval, unless renewed by the shareholders.

SHAREHOLDER RIGHTS PLAN

The purpose of the Shareholder Rights Plan is to provide shareholders and the Board with adequate time to consider and evaluate any unsolicited bid made for the Company, to provide the Board with adequate time to identify, develop and negotiate value-enhancing alternatives, if considered appropriate, to any such unsolicited bid, to encourage the fair treatment of shareholders in connection with any take-over bid for the Company and to ensure that any proposed transaction is in the best interests of the Company's shareholders.

The rights issued under the Shareholder Rights Plan will become exercisable only if a person, together with its affiliates, associates and joint actors, acquires or announces its intention to acquire beneficial ownership of shares which, when aggregated with its current holdings, total 20% or more of the Company's outstanding common shares (determined in the manner set out in the Shareholder Rights Plan), other than by a Permitted Bid. Permitted Bids must be made by way of a take-over bid circular prepared in compliance with applicable securities laws and, among other conditions, must remain open for 60 days. If a take-over bid does not meet the Permitted Bid requirements of the Shareholder Rights Plan, the rights will entitle shareholders, other than any shareholder or shareholders making the take-over bid, to purchase additional common shares of the Company at a substantial discount to the market price of the common shares at that time.

A copy of the Shareholder Rights Plan agreement has been filed on SEDAR.

Trevali returns deepest intercepts to date from Magistral Central and South deposits -- expands Magistral North footwall zones and Puajanca zone

 
6.75 metres at 100 g/t (2.9 oz/t) silver, 7.22% lead, 6.83% zinc & 0.18% copper 20.45 metres at 7.73% zinc & 0.12% copper


Vancouver, British Columbia...Trevali Resources Corp. ("Trevali" or the "Company") (CNSX: TV, Frankfurt: 4TI, Pink Sheets: TREVF) is pleased to announce receipt of final geochemical assay results from its 2009-2010 resource expansion, definition and geotechnical drilling program on its Santander silver-lead-zinc mine development project in west-central Peru. The 2009-2010 program was highly successful and exceeded the Company's technical expectations with all three Magistral deposits, the Puajanca South zone and the Santander Pipe remaining open for future expansion. The Company's proven exploration team has commenced screening and advancing several high priority geological -- structural -- geophysical -- geochemical anomalies (of similar tenor to known mineralization) to the drill testing stage.

"By any metric the current drill program has been incredibly successful. Our technical team has unequivocally demonstrated with the drill-rig a fundamental understanding of the controls on mineralization at Santander, which sits within the world's pre-eminent polymetallic mineral belt." stated Dr. Mark Cruise, Trevali's President and CEO. "I am confident that we will continue to expand our resource base through new discoveries on our large land-package going forward. Finally, our engineering and permitting teams continue to advance the project on all fronts towards anticipated production".

Key highlights of the approximately 12,500-metre, 61-hole diamond drill hole program include:
  • Intersection of thick, high grade mineralization at mid-to-lower deposit levels
    • Magistral North -- SAN-109A 31.75m at 3.4oz/t Ag, 4.86% Pb & 9.96% Zn
    • Magistral Central -- SAN-123 41.25m at 2oz/t Ag, 0.8% Pb, 8.2% Zn & 0.11% Cu
  • Intersection of significant mineralization beyond the current resource model at depth and along strike
    • Magistral South -- SAN-124 10.85m at 10% Zn
  • Discovery new zones of mineralization, in particular high-grade broadly E-W trending foot-wall zones
    • Magistral North SAN-158: 6.75m at 2.9oz/t Ag, 7.22% Pb, 6.83% Zn & 0.18% Cu
    • Magistral Central SAN-126: 6.75m at 2.9oz/t Ag, 4.12% Pb, 3.76% Zn & 0.1% Cu
  • Intersection of significant mineralization between the Magistral North and Central deposits -- SAN-142: 1.6m at 6.2oz/t Ag, 9.08% Pb, 12.17% Zn & 0.39% Cu; SAN-143: 1.9m at 7.8oz/t Ag, 11.32% Pb, 12.84% Zn & 0.98% Cu
  • Mineralization has been extended to approximately 350-to-400 metres vertically on all three Magistral deposits and remains open. The deepest intersections to date are as follows:
    • Magistral North -- SAN-096: 6.3m at 1.8oz/t Ag, 4.74% Pb & 4.18% Zn
    • Magistral Central -- SAN-165: 20.45m at 0.02% Pb, 7.73% Zn, & 0.12% Cu
    • Magistral South -- SAN-159: 4.4m at 0.9oz/t Ag, 0.55% Pb & 8.42% Zn
  • Intersection of significant mineralization on the Puajanca South zone with the latest hole, SAN-155 returning 4.3m at 1.8oz/t Ag, 2.91% Pb and 5.24% Zn. The Puajanca North prospect located some 450 metres to the north has returned surface values averaging 6.4oz/t Ag, 15.59% Pb and 7.18% Zn and is interpreted to represent high-level 'leakage' from an underlying polymetallic target.
  • Mineral system and empirical analysis suggests that all mineralized bodies have significant additional depth potential -- conservatively modelled to range from 300-to-500 additional vertical metres.
PROJECT BACKGROUND

The Santander silver-lead-zinc mine project is located approximately 215 km by road from Lima, in the western extent of Peru's world-class Central Polymetallic Belt. Site infrastructure includes a fully refurbished 200-man camp and the Tingo hydroelectric power-station located 17 km down-valley to the west. The Company commenced exploration at Santander in November 2007 discovering four new high-grade silver-lead-zinc replacement and massive sulphide bodies to date. Mineralization remains open in all three Magistral deposits, the Puajanca zone and the past-producing Santander Pipe, and numerous high-priority targets remain to be tested.

Trevali Intersects Broad Zones of Polymetallic Mineralization in Magistral Central drilling

 
52.75 metres at 59.3 g/t (1.7 oz/t) silver, 0.56% lead, 5.6% zinc & 0.1% copper


Vancouver, British Columbia...Trevali Resources Corp. ("Trevali" or the "Company") (CNSX: TV, Frankfurt: 4TI, Pink Sheets: TREVF) is pleased to announce that resource expansion drilling continues to intersect very thick zones of polymetallic mineralization at its Magistral Central deposit on the Santander silver-lead-zinc mine project in west-central Peru. Drill hole SAN-153 intersected approximately 130 metres of semi-massive to massive sulphide mineralization within which several broad intervals returned significant metal values including 23.65 metres at 69.7 g/t (2 oz/t) silver, 0.38% lead, 6.93% zinc and 0.16% copper.

Drill hole SAN-153 was targeted as an infill-test of the lower mid-level portions of the Magistral Central deposit in an area previously modelled as containing thin low-to-very-low grade polymetallic mineralization. Definition drill testing of these previously interpreted low-grade zones in all three Magistral deposits have returned some of the thickest and highest grade intercepts to date from the deposits.

An earlier drill-test of this previously interpreted low-grade zone within the Magistral Central deposit intersected the zone approximately 80-metres higher (nominally two sub-levels higher) and returned the highest-grade zinc intersection to date on the property -- SAN-123 with 42.25 metres at 71.1 g/t (2 oz/t) silver, 0.8% lead, 8.2% zinc and 0.11% copper within which a 9-metre interval returned 18.52% zinc. Inclusion of these thick, higher-grade zones could have significant implications for the forth-coming independent resource update tentatively scheduled for later in this second quarter of the year.

"The most recent assay results continue to increase the Company's leverage to forecast near-term global zinc shortages as several marquee zinc mines approach depletion of their resources," states Mark Cruise, Trevali's President and CEO. "All three Magistral deposits remain open as does the Puajanca zone -- intersection of such thick, broad intercepts greatly increases our goal of ultimately defining sufficient resources to merit increasing our planned processing capacity at the Santander polymetallic operation from 2,000 to 4,000 tonnes per day."

CORPORATE

Agreement was reached in the fall of 2009 between the Company and Compania Minerales Santander S.A.C. ("Santander") to suspend the Company's minimum monthly payment requirement of US$100,000 ("MMP") until such time as the Company has generated US$51,000,000 of revenue from its property at which time the Company will be obligated to recommence paying the greater of the monthly 3.5% NSR and the MMP. In consideration for the suspension of the MMP the Company agreed to advance to Santander by way of loan all necessary funds to cover the on-going costs of Santander's bankruptcy proceedings estimated to be US$250,000 per annum. Any funds advanced by the Company to Santander will rank as a first charge against the assets of Santander. In addition the Company was granted the exclusive right, up to September 30, 2014, to acquire the mineral concessions which comprise the property for a payment equal to the balance of the liabilities of Santander owing to others than the Company, on the date the Company exercises the right plus US$300,000.

The Board of Directors of the Company have approved the adoption of a Shareholder Rights Plan as a means of protecting the best interests of the Company's shareholders in the event of an unsolicited take-over bid for the Company's shares. This recommendation was made in light of (a) the Company's exploration and development work on its silver, zinc and lead property located in Province of De Huaral Deparmento de Lima, Peru and the recently announced partnership with Glencore International AG; and (b) the results of such work and the partnership may not reflect accurately the fair market value of the Company or its underlying share capital. The implementation of the Plan is subject to ratification by the shareholders of the Company at the Company's forthcoming Annual General Meeting scheduled to be held on May 27, 2010.

PROJECT BACKGROUND

The Santander silver-lead-zinc mine project is located approximately 215 km by road from Lima, in the western extent of Peru's world-class Central Polymetallic Belt.

Trevali drills additional high-grade mineralization in Magistral North, Central and South Deposits

 
Completes resource expansion drill program - mineralization remains open in all three zones

Highlights include:

North - 5 metres at 529.2 g/t (15.4 oz/t) silver, 7.47% lead, 13.15% zinc & 0.12% copper
Central - 1.9 metres at 268.4 g/t (7.8 oz/t) silver, 11.32 lead, 12.84% zinc & 0.98% copper


Vancouver, British Columbia...Trevali Resources Corp. ("Trevali" or the "Company") (CNSX: TV, Frankfurt: 4TI, Pink Sheets: TREVF) is pleased to announce the successful completion of its 2009-2010 resource expansion drill program on the Santander silver-lead-zinc mine project in west-central Peru. The 12,575-metre, 61-hole core drill program was very successful with essentially all definition holes intersecting sulphide mineralization. The final hole, SAN-165, was designed to test a deep extension of the Magistral North body and intersected semi-massive to massive sulphide mineralization as planned at approximately 400-metres downhole depth, approximately 80-metres vertically below the next nearest intercept. In addition to these exploration programs at Santander, Trevali along with partner Glencore International continue to fast-track the project towards production.

"These most recent assay results further demonstrate the strong technical fundamentals of the Santander project with high-grade silver--lead--zinc intercepts continuing to be returned from all three Magistral deposits," states Mark Cruise, Trevali's President and CEO. "All three Magistral deposits and the Puajanca zone remain open for expansion and the Company has yet to tackle the significant exploration upside on our large 44-km2 property package."

Key drilling highlights include:

  • Drill hole SAN-149, collared on the northern margin of the Magistral North deposit, intersected a thick interval of very high grade silver mineralization - 8.1 metres at 344.7g/t (10 oz/t) silver, 5.38% lead and 9% zinc within which higher grade intervals occur. The hole was designed to test an area adjacent to an interpreted major ~NE-SW trending feeder zone. This structure is traceable on surface approximately 1.1 km to the north-east where it also appears to control the Puajanca zone. As such it represents a significant high-grade silver structural target and will be aggressively pursued by future exploration programs.

  • Magistral North drilling continues to deliver multiple, thick polymetallic intercepts in a zone previously considered to be composed of lower-grade mineralization; Drill hole SAN-144 returned 15 metres at 52.6 g/t (1.5 oz/t) silver, 4.47% lead and 4.37% zinc.

  • Geotechnical and condemnation drilling in an area of potential ramp access between the Magistral North and Central deposits intersected numerous zones of sulphide mineralization. The broadly E-W to NE-SW trending 'feeder' zones comprise envelopes of up to +20 metres width containing lower grade mineralization within which narrow high grade structures and fracture zones occur. Drill holes SAN-142, 143 and 145 intersected zones of high-grade mineralization ranging from 1.5-to-1.9 metres width with grades ranging from 130.7 g/t (3.8 oz/t) to 268.4 g/t (7.8 oz/t) silver, 8.4% to 11.32% lead, 6.18% to 12.84% zinc and 0.24% to 0.98% copper. Mineralization remains open to the East and future exploration programs will further examine this potential.

  • Magistral South returned multiple zones of zinc-rich mineralization in areas outside of the current resource estimate.

  • Numerous other high priority targets and prospects remain to be drill tested: the Puajanca South prospect and the past-producing Santander Pipe both remain open at depth. In addition, several high-priority targets containing out-cropping mineralization and/or extensive alteration remain to be drill-tested -- for example, the El Toro prospect where higher-level alteration, 'productive' gangue and trace base metal mineralization occur in a structurally controlled zone over 1-km long and 150-metre wide, a similar surface expression to the currently defined Magistral deposits.

An updated, independent NI 43-101 resource estimate will be prepared upon receipt of the final assays from this drill program.

  PROJECT BACKGROUND

The Santander silver-lead-zinc mine project is located approximately 215 km by road from Lima, in the western extent of Peru's world-class Central Polymetallic Belt. Site infrastructure includes a fully refurbished 200-man camp and the Tingo hydroelectric power-station located 17 km down-valley to the west. The Company commenced exploration at Santander in November 2007 discovering four new high-grade silver-lead-zinc replacement and massive sulphide bodies to date. Mineralization remains open in all three Magistral deposits, the Puajanca zone and the past-producing Santander Pipe, and numerous high-priority targets remain to be tested on the Company's large, 100%-owned land package.

Trevali hits high-grade mineralization at Magistral Central and South -- intersects additional footwall zones

 
Highlights include:

Central -- 41.25 metres at 71.1 g/t (2 oz/t) silver, 0.8% lead, 8.2% zinc & 0.11% copper,
including 9 metres at 18.52% zinc, 105.1 g/t (3 oz/t) silver, 0.8% lead & 0.11% copper

South -- 10.85 metres at 10% zinc & 0.1% copper


Vancouver, British Columbia...Trevali Resources Corp. ("Trevali" or the "Company") (CNSX: TV, Frankfurt: 4TI, Pink Sheets: TREVF) is pleased to announce the intersection of significant high-grade mineralization in both the Magistral Central and South deposits on the Santander silver-lead-zinc mine project in west-central Peru. These hanging wall drill intercepts rank as some of the highest-grade intersections ever encountered on the project. Intercepts are located in areas previously expected to contain low-grade mineralization and/or situated outside of the currently defined resource envelopes. This will have a positive impact on future resource estimation.

Multiple zones of significant silver-lead-zinc mineralization has also been intersected in the footwall to the Magistral North deposit (including 1.35 metres at 12.3 oz (421.9 g/t) silver, 10.49% lead, 10.67% zinc and 0.29% copper). Additional footwall mineralization has also been intersected in the Magistral Central deposit -- 6.75 metres at 2.9 oz (98.8 g/t) silver, 4.6% lead, 3.94% zinc and 0.1% copper -- opening up the deposit to the East.

"Since the inception of exploration in late 2007 we have defined three deposits plus a fourth mineralized body and everything remains open. We are only now starting to focus on our large land holding and several other zones of out-cropping mineralization remain to be drill-tested," states Mark Cruise, Trevali's President and CEO. "Through this very successful exploration program we are also very fortunate to have Glencore International, a major integrated zinc miner and global commodity trader, as a partner to fast-track the project's engineering and mining aspects as we advance Santander to production"

Key drilling highlights include:

  • Magistral Central returns thickest, highest-grade zinc intersection to-date on the property (9 metres at 18.52% zinc) in a zone previously considered to be comprised of low-grade mineralization.

  • Magistral South returns the highest-grade intercepts to date from the zone (10.85 metres at 10% zinc). The hole was testing a deposit plunge concept and occurs outside the presently defined resource envelope.

  • Magistral North footwall zone continues to grow and expands upon the recently announced high-grade footwall intersections (see NR-10-2 for details). Predicted Magistral Central footwall 'feeder' mineralization also intersected.

  • Latest drilling opens up the Magistral deposits in multiple directions: Magistral North remains open at depth and to east-northeast, Magistral Central remains open at depth, to the south and to the east, Magistral South remains open at depth and to the north, and to the southeast near surface.

  • Numerous other high priority targets and prospects remain to be drill tested: the Puajanca South prospect and the Santander Pipe both remain open at depth. In addition, several high-priority targets containing out-cropping mineralization and/or extensive alteration remain to be drill-tested -- for example, the El Toro prospect where higher-level alteration, 'productive' gangue and trace base metal mineralization occur in a structurally controlled zone over 1 kilometre long and 150 metres wide -- a similar surface expression to the currently defined Magistral deposits.

DETAIL

The aim of the current round of drilling has been four-fold:

  1. in-fill drilling to provide additional intercepts in areas of less well-defined mineralization;

  2. to expand known mineralization - in particular along predicted deposit plunges;

  3. to complete various condemnation and geotechnical holes to aid mine planning and detailed engineering by our partners Glencore; and, finally

  4. to prove up the known E-W trending footwall 'feeder' zones.
In this regard, the results to-date have been extremely successful.

MAGISTRAL NORTH FOOTWALL

The lastest results continue to expand and better define the mineralized zones that occur below or in the footwall of the main Magistral North deposit. Boreholes SAN-125, 128 and 132 (see Table 1 for details) returned multiple intercepts of silver-rich footwall mineralization including another new footwall feeder zone (SAN-125).

In-detail, mineralization is comprised of a series of broadly E-W to NE trending structurally controlled fracture and veins zones with associated subordinate replacements. Previous intercepts include:

3.2 m @ 323 g/t (9.4 oz/t) Ag, 18.11% Pb, 15.97% Zn & 0.3% Cu
4.45 m @ 107.4 g/t (3.1 oz/t) Ag, 9.92% Pb, 10.3% Zn & 0.49% Cu
3.6 m @ 87g/t (2.5 oz/t) Ag, 8.4% Pb, 8.96% Zn & 0.11% Cu


Critically, the ongoing positive footwall results open up the immediate Magistral North deposit to the East-Northeast. Of particular note is the fact that this NE-trending mineralized structural corridor, which is up to approximately 200-metres wide at Magistral North, can be traced approximately 1000 metres along strike where it is interpreted to control the Puajanca North and South prospects. Exploration at Puajanca South is underway -- initial drill results returned:

6.7 m @ 81.9 g/t (2.4 oz/t) Ag, 3.37% Pb & 5.8% Zn
3.95 m @ 90.3 g/t (2.6 oz/t) Ag, 5.18% Pb and 8.19% Zn


Puajanca North has yet to be drill-tested, however, on surface it is comprized of a series of predominately galena (lead) veins and fracture-controlled mineralization mapped over approximately 500-metres strike length within which initial geochemical results returned average values of 220 g/t (6.4 oz/t) Ag, 15.59% Pb and 7.18% Zn (see news release TRC-NR-09-16 for details). Individual samples and veins ranged up to 26.5 oz/t (907.6 g/t) silver and 54.38% lead. This high grade silver mineralization is currently interpreted to represent high-level 'leakage' from an underlying polymetallic target.

MAGISTRAL CENTRAL

SAN-123 returned thick, high-grade mineralization at mid-deposit levels (approximately 200m vertical) in an area previously modelled as lower-grade, inferred mineralization. Perhaps even more significant, is the fact that this hole clearly validates a predicted high-grade plunge within the deposit. This easily targetable plunge has the potential to make a substantial contribution of tonnes and grade in the forthcoming resource model update. Borehole SAN-127, a mid-level deposit step-out, probed the southern margins of the deposit and returned 5.95 metres @ 148.4 g/t (4.3 oz/t) Ag, 1.99% Pb, 5.06% Zn & 0.19% Cu -- thereby opening up the Central deposit at depth to the south towards the Magistral South deposit. Finally SAN-126 tested predicted footwall mineralization and returned a very significant, thick footwall intercept -- 6.75 metres at 2.9 oz (98.8 g/t) silver, 4.6% lead, 3.94% zinc and 0.1% copper opening the deposit to the East.

MAGISTRAL SOUTH

Borehole SAN-124 was designed as a deep (~300m vertical) step-out to test the northern margins of the deposit -- it occurs approximately 40 metres beyond the current deposit margin and intersected the highest grade zinc intercept to date in the South deposit. The intercept demonstrates that Magistral South is open at depth and to the north towards Magistral Central.

PROJECT BACKGROUND

The Santander silver-lead-zinc mine project is located approximately 215 km by road from Lima, in the western extent of Peru's world-class Central Polymetallic Belt. Site infrastructure includes a fully refurbished 200-man camp and the Tingo hydroelectric power-station located 17 km down-valley to the west. The Company commenced exploration at Santander in November 2007 discovering four new high-grade silver-lead-zinc replacement and massive sulphide bodies to date. Mineralization remains open in all three Magistral deposits, the Puajanca zone and the past-producing Santander Pipe, and numerous high-priority targets remain to be tested on the Company's large, 100%-owned land package.

ACME's quality system complies with the requirements for the International Standards ISO 9001:2000 and ISO 17025: 1999. Analytical accuracy and precision are monitored by the analysis of reagent blanks, reference material and replicate samples. Quality control is further assured by the use of international and in-house standards. Blind certified reference material is inserted at regular intervals into the sample sequence by Trevali personnel in order to independently assess analytical accuracy. Finally, representative blind duplicate samples are routinely forwarded to ACME and an ISO-compliant third party laboratory for additional quality control.
