Diaz Cases First Well in Lloydminster Heavy Oil Development Program

Diaz Resources Ltd. (TSX VENTURE:DZR) announces today that it has successfully
drilled and cased the Lloyd HZ 105/15-18-48-1W4 well. This is the first of four
horizontal Lloydminster heavy oil wells which Diaz plans to drill in the 3rd
quarter of 2011. 


The Lloyd HZ 105/15-18-48-1W4 well encountered 709 meters of oil saturated
porous sand in the Lloydminster zone. Based on geological samples, the reservoir
section encountered in this well appears to be of higher quality than the
existing offset Lloyd HZ 100/15-18-48-1W4 well, which has produced over 18,000
barrels of oil, to date.


The second well, in the current Lloydminster drilling program, Lloyd HZ
106/15-18-48-1W4, began drilling on July 30, 2011. Both wells are anticipated to
be on production in approximately 2 weeks time, after the drilling rig has moved
off the production lease site. 


Diaz is an oil and gas exploration and production company based in Calgary,
Alberta. Diaz's current focus is on oil development and exploration in Alberta
and Saskatchewan.
