Houston American Energy Announces Test Results on Cachirre #1 Well
Houston, Texas – July 5, 2012 – Houston American Energy Corp. (NYSE MKT: HUSA) today announced test results on the C-9 sand in the Cachirre #1 well.

After plugs are set, the drilling rig will move to the Zorro Gris well location to begin drilling operations on the next well on CPO 4.
