Palmarejo Silver and Gold Corporation Announces Further Drill Results From the Guadalupe Project

LONGUEUIL, QUEBEC--(Marketwire - Sept. 13, 2007) - Palmarejo Silver and Gold Corporation (TSX VENTURE:PJO) (the "Company") is pleased to announce results from the continuing reverse circulation (RC) and diamond drill program at its Guadalupe project, 7.0 kilometres southeast of the Palmarejo Project, in the Temoris District, Chihuahua, Mexico.

The Guadalupe project consists of a series of northeast dipping quartz veins that have been traced for more than 2,000 metres along strike. There are three main prospects located along the Guadalupe structure known from north to south as Guadalupe Norte, Guadalupe and Las Animas. A fourth prospect, El Salto, has been identified by surface mapping as a link structure between Las Animas and Guadalupe. El Salto has only been tested by near surface drilling.

Thirty four holes have been drilled for 2,555 metres of RC and 7,072 metres of diamond core (including two core continuations of RC, and one wedge hole) since the previous drilling update on 24 July 2007. Some of the better results from recent drilling are reported below as down hole intercepts. Where there is a difference between down hole and true width intercepts these are noted in the table of full assay results recorded below.

Assay Results are available at the following address:


- Assays have been calculated using a 1.0 g/t AuEq cut off, no top cut and a gold to silver price ratio of 1:60.

- Metallurgical recoveries and smelter returns are assumed to be 100%.

- QVBX equals quartz vein breccia, HYBX equals Hydrothermal breccia, CBBX equals Carbonate breccia.

- GPE equals Guadalupe and Guadalupe prospects, LA equals Las Animas

- # equals previously reported and included here for completeness.

- Bulked intercepts are calculated by weight averaging the grades between the given depths and incorporating a maximum dilution of 2 metres internal waste at less than the 1.0 g/t AuEq cut off.

- Results are awaited for drill holes TGDH150D, TGDH153D, TGDH155D, TGDH156D, TGDH158D, TGDH159D, TGDH161D, TGDH163D to TGDH186.

The attached long section highlights the intercepts reported in this drilling update:

At Las Animas, holes TGDH128D and TGDH140D were drilled towards the centre of the prospect and intersected wide, high-grade and narrow, very high-grade mineralization respectively. Holes TGDH141 and TGDH143D, drilled near the centre of the prospect, intersected low- to medium-grade mineralization.

Holes TGDH149D and TGDH151D intersected medium to low-grade mineralization on the southern margin of Las Animas and extends the medium-grade clavo outline 80 metres to the southeast. Hole TGDH144D intersected low to medium-grade mineralization on the northern margin of Las Animas.

At Guadalupe, hole TGDH154D intersected low-grade mineralization and pierced the structure down-dip of TGDH094 (10.67 metres @ 0.61 g/t Au and 108 g/t Ag), which was abandoned within a quartz-bearing structure.

At Guadalupe Norte, holes TGDH_145D and TGDH148D were drilled deep of the GC1 clavo with the later hole intersecting a narrow very high-grade structure. Holes TGDH133D and TGDH133W intersected wide, medium to high-grade mineralization down-dip of the significant TGDH110D (10.50 metres @ 7.10 g/t Au and 294 g/t Ag).

Holes TGDH147D and TGDH157D were drilled at the GC2 clavo and both intersected wide, medium to high-grade mineralization in principal and footwall structures. Significantly hole TGDH157D was abandoned within a mineralized structure due to ground conditions. Hole TGDH138D pierced medium to low-grade mineralization in the principal and footwall structures between GC2 and GC3 clavos. Hole TGDH142D also intersected high-grade principal and footwall mineralization and extends the GC3 clavo down-dip of TGDH115D (16.50 metres @ 1.83 g/t Au and 156 g/t Ag).

Holes TGDH152 and TGDH162D were drilled 240 metres northwest of the GC3 clavo and intersected wide, medium to low-grade mineralization.

Holes TGDH146, TGDH160 and TGDH180D are not shown on the long section as they were terminated short of target depth due to heavy water inflow causing an inability to sample RC cuttings dry and difficult ground conditions.

A total of 75 RC holes for 16,556 metres and 112 diamond core (including ten diamond core continuations of RC holes, and two wedge holes) for 37,251 core metres have been drilled at Guadalupe since drilling commenced in mid-2005.

Forward Looking Statement

Some of the statements contained in this press release are forward-looking statements. Forward-looking statements are not historical facts and are subject to a number of risks and uncertainties beyond the Company's control, including statements regarding resource estimates, potential mineralization, exploration results, completion of work program and studies, and future plans and objectives of the Company. Resource exploration, development and operations are highly speculative, characterized by a number of significant risks, which even a combination of careful evaluation, experience and knowledge may not eliminate, including, among other things, unprofitable efforts resulting not only from the failure to discover mineral resources but from finding mineral deposits which, though present, are insufficient in quantity and quality to return a profit from production. There can be no assurance that such statements will prove to be accurate and actual results could differ materially from those suggested by these forward-looking statements for various reasons discussed throughout the Company's Annual Information Form dated October 12, 2006 and particularly in the section entitled "Risk Factors".
