VANCOUVER, British Columbia – February 22, 2010 – Silvercorp Metals Inc. (“Silvercorp” or “the Company”) has signed a definitive purchase agreement with Silver Standard Resources Inc. (“Silver Standard”) to purchase a 100% interest in the Silvertip silver-lead-zinc project covering 216 km2 in northern British Columbia, Canada. Total consideration for the project is CDN$15-million with up to 50% to be paid in Silvercorp common shares and the balance in cash. The closing date is expected on or before February 26, 2010.
Located just south of the Yukon border and readily accessible by a 25-kilometre road from the Alaska Highway, the Silvertip property hosts an advanced-stage, high-grade silver-lead-zinc carbonate replacement deposit system. The project was previously explored by various operators/owners from 1955 to 2000 with more than $40 million in exploration work carried out — including 2,400 metres of underground tunnel development and 71,472 metres of surface and underground drilling in 491 holes. The most recent exploration work was carried out by Imperial Metals Corporation (“Imperial Metals”), which owned the project from 1996 to 2002. No exploration work was conducted by Silver Standard since acquiring the project in 2002.
A resource estimate was calculated for the Silvertip project in 1997 within an area of 1,000 metres by 800 metres, which was then converted into a National Instrument 43-101 compliant resource in October 2002 (“the 2002 Resource”). The resource is summarized below:
Silvertip 2002 Resource Calculation
(Based on exploration results to the end of 1997)
Resource Category | Tonnes | Silver (g/t) | In Situ Contained Silver (oz) | Lead (%) | Zinc (%) | Gold (g/t) |
Indicated | 1,120,000 | 378 | 13,612,900 | 7.7 | 9.5 | 0.85 |
Inferred | 1,450,000 | 284 | 13,241,200 | 5.4 | 8.3 | 0.46 |
According to the 2002 technical report, “[t]he Silvertip mineralization is a silver-zinc-lead Carbonate Replacement Deposit (CRD) with metals content, polyphase mineralization, abundant replacement textures, pyrite pseudomorphing pyrrhotite, and wallrock alteration reminiscent of many of the manto-chimney CRD’s of Mexico and the western US (Megaw, 1998).” The Silvertip resource identified to date is considered to be only the distal portion of a CRD, indicating considerable tonnage may be added through a concerted exploration effort. When the entire system is accounted for, other CRD deposits with similar characteristics have ranged in size from 11.7 million tonnes (Gilman, Colorado) to approximately 30 million tonnes (Santa Eulalia, Chihuahua).
Prior to the signing of the definitive purchase agreement, Silvercorp engaged Mr. Randy Cullen, P.Geo., to carry out a resource evaluation by reviewing all available exploration reports and data and compiling a new geological model for the Silvertip project using SURPAC® software. This model includes exploration results from a 1999-2000 drill campaign designed to test geophysical anomalies discovered in the summer of 1999 by Imperial Metals. In that campaign, drill hole SSD-99-65 intercepted 31.4 metres grading 318.4 g/t silver, 5.52% lead and 8.65% zinc. Subsequently, in the winter of 2000, 22 underground diamond drill holes delineated the high-grade “65 Zone”.
A new NI 43-101 compliant resource update dated February 19, 2010 (the “2010 Resource”), now including the “65 Zone” as well as significant drill hole interceptions, will be filed on SEDAR at www.sedar.com and posted on the Company’s website (www.silvercorp.ca). The updated 2010 Resource is summarized below:
Silvertip 2010 Resource Calculation
(Including exploration results up to and including the winter of 2000)
At >200 g/t Silver Equivalent Cut-off | ||||||
Resource Category | Tonnes | Silver (g/t) | In Situ Contained Silver (oz) | Lead (%) | Zinc (%) | Gold (g/t) |

Inferred | 120,569 | 739 | 2,864,647 | 12.99 | 14.59 | 0.51 |
*Silver Equivalent is calculated using metal prices of US$12.13/oz Ag, US$728/oz Au, US$0.804/lb Pb and US$0.847/lb Zn and metal recoveries of 69.2% for silver, , 80.4% for lead, 84.7% for zinc and 50% for gold.
**The increase in the resource is mainly attributed to the inclusion of the “Zone 65” resource. The conversion of tonnes from the Inferred to the Indicated category is based on the drill demonstrated continuity of the mineralization.
Preliminary metallurgical testwork was conducted in 1998 by CSMA Minerals laboratory in the UK. The test result showed that with a lead concentrate grade of 65%, silver and lead recoveries are 69.2% and 80.4%, respectively, and a 61% zinc concentrate grade has a zinc recovery of 84.7%. The Company plans to perform additional mineralogy study and a metallurgical test program to further increase metal recoveries.
Silvercorp also intends to carry out a regional exploration program outside of the existing resource area including geophysical and geochemical surveys to identify new drill targets. Concurrent with its exploration program, Silvercorp intends to apply for a provincial Small Mine Permit for an operation with a capacity of under 75,000 tonnes per year. Once permitted, Silvercorp plans to start mining those high grade pockets (outlined in the table above using >1,000 g/t silver equivalent cut-off grades) which are already accessible from existing tunnels. The cash flows to be generated from these early operations will then be used to finance further exploration programs, a full feasibility study, a full mining permitting process, and future expansion of mining operations.
Silvercorp recognizes the imperative of First Nations support for the project. Accordingly, Silvercorp has signed a Resource Funding Agreement and commenced negotiating a Traditional Knowledge Protocol and a Memorandum of Understanding with the Kaska Dena Council as the Silvertip property lies within the Kaska traditional territory. With the definitive purchase agreement now signed, the Company will widen its consultation to actively engage other First Nations and all interested stakeholders.
“With grades of 12.8 ounces per tonne [398 g/t] silver and 18% combined lead and zinc in the indicated category [at a >400 g/t cut-off] and higher grade starter pockets, the Silvertip project ranks among one of the highest grade silver-lead-zinc carbonate replacement deposits in North America — with great potential to grow,” states Dr. Rui Feng, Silvercorp’s Chairman and CEO. “While we will continue to focus on growing in China, we are excited to acquire this advanced stage exploration project in Canada, giving us an additional platform for growth plus geographic diversification.”
“Silvercorp has a proven track record in the accelerated development and mining of high-grade underground precious metals deposits, a strategy that benefits both our shareholders and the communities in which we operate. We will apply the same successful strategy we used at our Ying mine in China to the Silvertip project, with a focus on commencing small scale production at the earliest possible date and using the cash flow generated from operations to help finance further expansion of the project.”
