Mercator Intersects 82.2 Metres Averaging 0.085% Molybdenum at El Creston

Lengthy Sections of Molybdenum Intersected Outside of the Main/Red Hill Deposit

VANCOUVER, BRITISH COLUMBIA--(Marketwire - July 27, 2011) - Mercator Minerals Ltd. (TSX:ML) ("Mercator" or the Company") today announces assay results from four exploration diamond drill holes recently completed at its El Creston molybdenum project, located in northern Sonora State, Mexico. The holes were drilled into the A-37 and Red Hill Deep zones to test their potential to host resources in addition to those at the El Creston Main/Red Hill deposit. Two holes EC11-148 and 149 tested the A-37 zone, with two holes EC11-150 and 151 testing the Red Hill Deep zone.

Drill highlights include:

  • Hole EC11-148 intersecting a near surface intercept of 176.9 m averaging 0.052% molybdenum including 82.2 m averaging 0.085% molybdenum;
  • Hole EC11-150 intersecting 420.3 m averaging 0.047% molybdenum, including a 56.4 m section averaging 0.087% molybdenum with 0.113% copper and;
  • Hole EC11-151 intersecting 221.8 m averaging 0.050% molybdenum including an 84 m section averaging 0.076% molybdenum.

"Drilling at the El Creston molybdenum project continues to intersect potentially significant mineralization," said Bruce McLeod, President & CEO of Mercator. "The results from the holes released today clearly demonstrate the existence of multiple zones around the Main/Red Hill deposit. Additional drilling will be required to determine the economic viability of the zones, however they appear to have the potential to add to the existing resources."

Drill Results

Maps showing the drill hole locations are available at or or click the link below to view the map showing the drill hole locations.

The A-37 Zone is located approximately 100 m to the south of the Main/Red Hill deposit. In 1974 Amax drilled one hole into the zone intersecting a near surface intersection averaging 0.094% molybdenum over 74 m. Holes EC11-148 and 149 were drilled to test the continuity of this intersection.

Hole EC11-148, an angle hole collared approximately 80 m due south of hole A-37, was drilled towards the north with the objective of determining the width of the zone. The hole intersected a 176.9 m section, commencing at a down-hole depth of 29.6 m, averaging 0.052% molybdenum. Within this intercept there is an 82.2 m high grade section averaging 0.085% molybdenum. The northern edge of the high grade intercept corresponds with the zone intersected in Hole A-37.

Hole EC11-149, collared 100 m to the west of EC11-148 was drilled due north at a dip of -45°. The hole did not intersect any significant molybdenum values.

The Red Hill Deep Zone is located below and to the south and east of the Red Hill Zone. Limited drilling completed by Amax and Creston Moly Corp. showed lengthy intersections of molybdenum + copper mineralization to occur at depth. Previous results are listed below.

Hole EC11-150, was drilled due north at -70° to test the continuity of the mineralization intersected in Hole EC08-062 located 180 m to the north. The hole intersected, (from 155.6 m to the end of the hole), a 420.3 m section averaging 0.047% molybdenum, including a 56.4 m section averaging 0.087% molybdenum with 0.113% copper. The hole extended the Red Hill West Zone laterally 120 m to the south and vertically 60 m. Anomalous copper values occur throughout the hole and include an 82.4 m section commencing at 353.1 m averaging 0.104% copper.

Hole EC11-151 collared 180 m to the southeast of Hole EC08-62, was drilled to determine the continuity of the zone intersected in Hole EC08-62. The hole intersected a 292.8 m section averaging 0.044% molybdenum with 0.042% copper in which there are higher grade sections including an 84 m section averaging 0.076% molybdenum. Anomalous copper values occur throughout and include a 36.8 m section averaging 0.067% copper commencing at 322.8 m.

The drilling has shown the A-37 Zone to host near surface molybdenum mineralization that appears to be cut-off to the west but open to the south and in part to the east.

The limited amount of drilling completed on the Red Hill Deep Zone has traced molybdenum + copper mineralization for up to 310 m from north to south, and vertically of up to 390 m over a strike length of 850 m with the zone open in all directions.

Additional drilling is required to determine the significance of the A-37 and Red Hill Deep Zones.
