Madalena Ventures Inc. (the “Company” or “Madalena” is pleased to provide the following updates:
International Operations Update – Neuquen Basin
In Argentina, exploration and delineation activity continues on the Company’s large petroleum in-place unconventional shales and conventional tight sand plays. In the southern portion of the Coiron Amargo
block (Madalena 35% W.I.), Madalena continues to define and quantify the Vaca Muerta shale potential
on the block with the recent drilling of the CAS X-5 exploration well.
The CAS X-5 location was drilled to a total depth of 3,400 meters (or 11,155 feet) and encountered hydrocarbon in the Vaca Muerta as expected. CAS X-5 has now been cased with approximately 100 meters of Vaca Muerta shale on logs and an average total organic content (“TOC”) over the 100 meter section of over 4%, confirming the high
quality of the Vaca Muerta on the block. Based on technical information gathered to date, Coiron
Amargo has some of the highest TOC content within the Neuquen basin, and based on core data on the
block, the lower Vaca Muerta at CAS X-5 is expected to have approximately 7% porosity.
With recent Joint Venture partnerships being announced near the Coiron Amargo block by both Chevron
and Bridas (on YPF held acreage) for an estimated U.S. $1.0 - $1.5 billion to earn various working
interests in the Vaca Muerta shale, Madalena is focused on continuing to delineate and prove-up this
significant resource at Coiron Amargo. Madalena is also actively working to move forward on its other
two blocks within the Neuquen basin at Cortadera (40% W.I.) and Curamhuele (90% W.I.).
