By e-lodgement 
Range Resources Limited ("Range" or "the Company") is pleased to
announce the following update with respect to the Company's Trinidad
operations with the following highlights: 
- The QUN 135 well makes discovery of a new oil reservoir in the
Middle Cruse formation, indicating 50 ft. of net oil pay at approximately
3,500 ft., with the well successfully cemented with 5½" casing; 
- The QUN 138 well successfully drilled and put into production
with initial rates (five day average) of approximately 85 bopd; 
- The QUN 139 well successfully reached revised target depth of
1,300 ft. and encountered total of 70 ft. of good quality oil sands, and 190
ft. of lower resistive oil sands in the Lower Forest formation to be
perforated later this week; and 
- The QUN 133 well perforated and drilling to commence on QUN 140
and QUN 141 wells - all targeting the Lower Forest Formation. 
Middle Cruse Formation Drilling 
The Company is pleased to report that following the successful
deepening of the QUN 135 well to a revised target depth of 3,800 ft., the
Company has made an apparent discovery of a new oil reservoir in the Middle
Cruse section between 3,490 - 3,540 ft. measured depth. Open hole logs
indicate 50 ft. of previously unseen oil pay with porosities in the 21-23%
range, while offset well control indicate that the identified reservoir
section has significant areal extent. 
As previously announced the well reached a depth of 3,500 ft. and
logging indicated the presence of additional resistive oil sands. The Company
subsequently deepened the well and confirmed the presence of a new oil
reservoir. Production casing has been run and testing will now commence. Range
is extremely pleased with the results of the Company's first Middle Cruse
well, with the apparent discovery of a new oil reservoir in the Middle Cruse
formation along with the additional resistive sands encountered in both the
Lower Forest and Upper Cruse formations. 
Lower Forest Development Update 
Following receipt of the approvals, the QUN 138 well was
successfully perforated and placed into production with initial production
rates of 85 bopd over the first five days under a 6/32" choke size. The
Company will continue to monitor the performance of the well and may look to
increase the choke depending on the performance of the well. 
The QUN 139 well has reached its revised target depth of 1,300 ft.
and encountered the presence of 70 ft. of high resistive oil sands in addition
to 190 ft. of lower resistive oil sands in the Lower Forest formation. Casing
has been set and cemented and approvals received to perforate the well and be
placed into production later this week. As previously announced, the QUN 139
well location is contiguous to producing wells QUN 119 and QUN 129 which
achieved initial production rates of 129 bopd and 138 bopd, respectively. Both
wells still flow under natural pressure (QUN 129 and QUN 119 are currently
producing 65 bopd and 45 bopd respectively) with QUN 119 having now produced
for 12 months since first production. 
Approvals have been received to commence drilling of the QUN 140
and QUN 141 wells, which will continue the development of the Lower Forest
trend, being contiguous and up-dip to the recently completed and successful
QUN 138 well. 
In addition to the wells mentioned above, the Company is looking to
commence remedial work on four wells that have experienced comingling of oil
and water sands. Remedial work will be performed on these wells with a small
work-over rig, with additional perforations to be added in two of the four
wells. This work is expected to improve the performance of these wells and add
further to production. 
As such, the company has perforated the Lower Cruse formation of
the QUN 133 well, which experienced oil and water sands comingling in the
Upper Cruse and will now assess performance under pump. 
Executive Director Peter Landau commented: 
"We are extremely pleased with the results of the ongoing drilling
program in Trinidad, and particularly with the discovery of new oil reservoir.
The QUN 135 well confirms once again that the development potential on Range's
Trinidad blocks remains largely untapped. Once production testing of this new
zone is complete, we will make a determination as to how best to develop the
reservoir as part of our expanding portfolio of exploratory, development, and
secondary recovery opportunities in Trinidad." 
Further Updates 
The Company will be providing further updates shortly with respect
to the MD 248 well, finalisation of the sale of the Company's Texas interests,
the finalisation of the GIG joint venture in Georgia, well performance in
Guatemala and financing arrangements. 
Yours faithfully

Range Resources Limited is a dual listed (ASX:RRS; AIM:RRL) oil & gas
exploration company with oil & gas interests in the frontier state of
Puntland, Somalia, the Republic of Georgia, Texas, USA, Trinidad and Colombia. 
- In Trinidad Range holds a 100% interest in holding companies with
three onshore production licenses and fully operational drilling subsidiary.
Independently assessed Proved (P1) reserves in place of 17.5 MMbls with 25.2
MMbls of proved, probable and possible (3P) reserves and an additional 81
MMbls of unrisked best estimate prospective resources. 
- In the Republic of Georgia, Range holds a 40% farm-in interest in
onshore blocks VIa and VIb, covering approx. 7,000sq.km. Range completed a
410km 2D seismic program with independent consultants RPS Energy identifying
68 potential structures containing an estimated 2 billion barrels of
undiscovered oil-in-place (on a mean 100% basis) with the first (Mukhiani-1)
exploration well having spudded in July in 2011. The Company is focussing on a
revised development strategy that will focus on low-cost, shallow appraisal
drilling of the contingent resources around the Tkibuli-Shaori ("Tkibuli")
coal deposit, which straddles the central sections of the Company's two
- In Puntland, Range holds a 20% working interest in two licenses
encompassing the highly prospective Dharoor and Nugaal valleys. The operator
and 60% interest holder, Horn Petroleum Corp. (TSXV:HRN) has completed two

SPE Definitions for Proved, Probable, Possible Reserves and
Prospective Resources 
Proved Reserves are those quantities of petroleum, which by
analysis of geoscience and engineering data, can be estimated with reasonable
certainty to be commercially recoverable, from a given date forward, from
known reservoirs and under defined economic conditions, operating methods, and
government regulations. 
Probable Reserves are those additional Reserves which analysis of
geoscience and engineering data indicate are less likely to be recovered than
Proved Reserves but more certain to be recovered than Possible Reserves. 
Possible Reserves are those additional reserves which analysis of
geoscience and engineering data indicate are less likely to be recoverable
than Probable Reserves. 
1P refers to Proved Reserves, 2P refers to Proved plus Probable
Reserves and 3P refers to Proved plus Probable plus Possible Reserves. 
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. Prospective Resources are further subdivided in accordance with
the level of certainty associated with recoverable estimates assuming their
discovery and development and may be sub-classified based on project maturity. 
Contingent Resources are those quantities of hydrocarbons which are
estimated, on a given date, to be potentially recoverable from known
accumulations, but which are not currently considered to be commercially
Undiscovered Oil-In-Place is that quantity of oil which is
estimated, on a given date, to be contained in accumulations yet to be
discovered. The estimated potentially recoverable portion of such
accumulations is classified as Prospective Resources, as defined above.
