Wealth Minerals Discovers Bonanza Uranium grades at Bororo Nuevo Property, San Jorge Basin, Argentina

Values average 0.44% uranium (10.3 lbs/ton U₃O₈) with
a maximum of 6.4% uranium (151.1 lbs/ton U₃O₈)

Vancouver, British Columbia…  Wealth Minerals Ltd. (the “Company” or “Wealth”) - (TSX Venture Exchange: WML, OTC: WMLLF, Frankfurt: EJZ), is pleased to announce that it has received final assay results from its newly discovered, 100% owned, high-grade Bororo Nuevo uranium property in southern Argentina.

Results from the initial 79 samples collected at Bororo Nuevo have now been finalized.  The average of the uranium values from all samples is 0.44% uranium (10.3 lbs/ton U₃O₈) and the over-limit values range from 1.2 to 6.4% uranium (28.8 to 151.1 lbs/ton U₃O₈).

Additionally, a new zone of uranium mineralization has been identified over an area of approximately 300 square metres located approximately 2 kilometres to the north of the original discovery zone.  Samples collected from the area have scintillometer readings ranging from 4100 counts per second (cps) to ‘off-scale’ (more than 9999 cps).  The samples have been submitted for assay and results are pending.  With the discovery of this new zone, the Company has now identified a “uranium fairway” approximately 7 kilometres long by 3 kilometres wide (Figure 1).

The initial reconnaissance sample results are highly encouraging, with over seventy percent the samples returning values in excess of 1 lb/t U₃O₈ (see NR07-06 for details).  The upper-most eleven percent of the samples returned values above the detection limit of the analytical method chosen (10,000 parts per million or 1% uranium).  Consequently, these samples were re-analyzed by the certified laboratory and produced the following results:

Sample Number	Sample Type	Width (m)	U (%)	U (lbs/ton U3O8)	Cu (%)
781RCB-71	rock	grab	2.1	49.6	0.07
781RCB-72	rock	grab	2.6	62.6	0.11
781RCB-76	rock	0.60	1.4	32.5	0.24
781RCB-85	rock	0.30	2.6	61.6	0.34
781RCB-88	rock	0.20	1.9	43.9	1.17
781RJM-99	rock	grab	1.3	31.1	0.02
781RJM-100	rock	grab	2.1	49.8	0.04
781RJM-102	rock	grab	6.4	151.1	1.04
781RJM-103	rock	0.20	1.2	28.8	0.49

Note:

Laboratory results are received in parts per million uranium.  The conversion factor used to convert parts per million uranium to pounds per short ton U₃O₈ is 1.179 (ppm uranium x 1.179 = ppm U₃0₈; 10,000 ppm uranium = 1% = 20 lbs/ton uranium).

Bororo Nuevo Property

The newly discovered Bororo Nuevo property forms part of the Company’s extensive land-holdings targeting high-grade uranium mineralization in the productive San Jorge Basin, southern Argentina.  There has been no systematic exploration on the property and mineralization remains open in all directions, most specifically to the north and south and at depth.  The property lies within the same productive basin that hosts the Cerro Solo uranium deposit (reported to contain a resource of 10.3 million pounds of U₃O₈ at an average grade of 0.3% uranium and a potential 0.3% molybdenum credit).

Mineralization has now been identified in eight separate mineralized outcrop clusters, whose host unit thicknesses range from 0.5 to 1.5 meters thick, within a uranium fairway now measuring approximately 7 kilometres long by up to 3 kilometres wide (see Figure 1).

In light of these initial highly encouraging results, the Company has planned a very aggressive follow-up exploration program designed to take the Bororo Nuevo property to an initial drill test as soon as possible.  Experienced uranium field crews are currently conducting detailed geological mapping and systematic sampling over the mineralized zones and the surrounding ground and planning is underway for an airborne radiometric and magnetic geophysical survey.

Diamante-Los Patos Property

The Company also continues to aggressively advance its large Diamante–Los Patos property in north-western Argentina, where field crews are focused on the mapping and sampling of trenches at the Alfredo and recently discovered Bingo Zones (see NR07-03).  Initial chip sampling of surface exposures at the Bingo Zone returned values of 3.4 lbs/ton U₃O₈ over 6.5 metres.  Planning of an airborne radiometric and magnetic geophysical survey and the initial drill testing of the project is presently underway.
