Sterling Resources Announces Updated Contingent and Prospective Resources for Cladhan

CALGARY, Alberta, October 19, 2010 /PRNewswire-FirstCall/ -- Sterling Resources Ltd. (TSX-V:SLG) ("Sterling" or the "Company") is pleased to announce updated Contingent and Prospective Resource numbers (100 percent) for the Cladhan discovery (UKCS Blocks 210/29a and 210/30a) as a result of recently announced drilling success of two sidetracks from the original discovery well 210/29a-4. These Contingent and Prospective Resource figures (100 percent) have been evaluated by RPS Energy as at October 15, 2010.

P50 Contingent Resources have increased from 30 million barrels Oil in Place (OIP) to 89 million barrels OIP.

P50 Prospective Resources have increased from 65 million barrels OIP to 93 million barrels OIP in the previously assessed terrace area. An additional 74 million barrels OIP of P50 Prospective Resources is attributable to an area off the terrace and in a fan system to the east previously not assessed by RPS Energy.

"These revised Contingent and Prospective Resources numbers independently confirm the magnitude of our recent drilling successes at Cladhan," stated Mike Azancot, Sterling's President and CEO. "The significant upward revisions from just two new data points in high quality sands in which we have yet to find an oil water contact indicate the large potential for Cladhan. Additional drilling will be required to further delineate the size of this discovery," added Mr. Azancot.

Subject to the completion of site survey work already in progress, conclusion of the rig selection process and regulatory approval from the UK Department of Energy and Climate Change (DECC), the Company anticipates performing another drilling campaign at Cladhan during the first quarter of 2011. The Company is also initiating evaluation work for potential development scenarios.

Sterling is the operator of Cladhan (License P1064) and holds a 39.9 percent working interest through wholly-owned Sterling Resources (UK) Ltd. The other partners are Wintershall (UK North Sea) with a 33.5 percent working interest, Encore Petroleum Ltd. with a 16.6 percent working interest and Dyas UK Ltd. with a 10 percent working interest.

1. Contingent Resources are those quantities of petroleum estimated, as of a given date, to be potentially recoverable from known accumulations using established technology or technology under development, but which are not currently considered to be commercially recoverable due to one or more contingencies. Contingencies may include factors such as economic, legal, environmental, political, and regulatory matters, or a lack of markets. It is also appropriate to classify as Contingent Resources the estimated discovered recoverable quantities associated with a project in the early evaluation stage. Specific contingencies preventing the classification of the resources as reserves are further definition of resource volumes through further appraisal drilling, regulatory approvals and sanction, and selection of a specific field development concept, including the most viable crude offtake delivery routing and oil sales contracts.

2. Prospective Resources are those quantities of petroleum estimated, as of a given date, to be potentially recoverable from undiscovered accumulations by application of future development projects. Prospective Resources have both an associated chance of discovery and a chance of development.

3. The P50 or 2C is considered to be the best estimate of the quantity that will actually be recovered. If probabilistic methods are used there should be at least a 50 percent probability P50 that the quantities actually recovered will equal or exceed the estimate. Similarly, the 1C or P90 and 3C or P10 represent the low and high estimates respectively.

As with all oil and gas fields at this early stage of appraisal, there are significant positive and negative factors which may impact the resource volumes for Cladhan. There is a significant range of uncertainty associated with the resource volumes due to variations in geological properties, reservoir petrophysical properties and potential well flow rates in the undrilled portions of the reservoir structure.

In the case of discovered resources or a subcategory of discovered resources there is no certainty that it will be commercially viable to produce any portion of the resources. In the case of undiscovered resources or a subcategory of undiscovered resources, there is no certainty that any portion of the resources will be discovered. If discovered, there is no certainty that it will be commercially viable to produce any portion of the resources.
