GUATEMALA UPDATE 
Range Resources Limited ("Range" or the "Company") is pleased to
announce the following update with respect to its recent investment in
Citation Resources Limited ("Citation") - 19.9% interest in Citation and 10%
at project level - regarding the Atzam #4 Well update released by Citation
(ASX:CTR) today: 
- Testing continuing on Lower C17/Upper C18 carbonate sections -
  perforated zones cleaning up with increasing recoveries of oil; 
- High quality oil (37.0° API) recovered during testing operations; 
- Estimated flow rates of 300-400 bbl/day with an 85-90% oil cut from 
  Lower C17/Upper C18 carbonates with an operational submersible pump,
  based on results to date; 
- Upper C18 carbonates displayed impressive log results with permeability 
  averaging 300 md and porosity averaging 17% - Rubelsanto Field
  (+30mmbbl produced) is 100md and 3-6% porosity; and 
- Significant moveable oil identified in electric logs over C13 and C14 
  carbonate sections still untested- remain behind pipe above the current
  perforated Lower C17/Upper C18 sections. 
Flow testing operations on the perforated Lower C17/Upper C18
carbonate sections in the Atzam #4 well are continuing, with encouraging
results from the well having been received over the past two weeks. Latin
American Resources Ltd, Operator of the Atzam Oil Project in Guatemala, has
continued swabbing the well to recover the drilling and perforation fluids
and establish the commercial potential of the perforated Lower C17/Upper C18
carbonates. 
The Operator is now arranging to use an Electrical Submersible Pump
("ESP") to help fast track the finalisation of the clean-up operations and
establish the commercial potential of these perforated zones. The Operator
estimates that, with an ESP operational and based on the results to date from
the perforated Lower C17/Upper C18 carbonates, the potential flow rate will be
approximately 300-400 bbl/ day with an 85-90% oil cut. It is estimated that
approximately 50% of the total drilling and perforation fluids used in the
operations have now been recovered. 
The ESP is currently being sourced from the United States and the Operator
expects that it should be landed on site and operational in two to three
weeks. 
The recovery of high quality (37.0° API) oil from recent swabbing of the
perforated Upper C18 sections, with continued pressure build ups prior to
commencement of acid wash operations, is considered very encouraging by the
Operator for the potential of this section. Due to the heavy muds used whilst 
drilling (10.5 lb/gallon) and high permeability of these
carbonates, there were significant mud losses into the Upper C18 section
whilst drilling, which required the acid wash to establish a clear oil cut and
flow rates from these zones. 
Testing Highly Prospective C13 and C14 Carbonates in Atzam #4 
The Atzam #4 well produced very encouraging, and unexpectedly strong, oil
shows during the drilling of the well through the C13 and C14 carbonates,
which was complemented by higher than expected permeability and porosity
results from the electric logs. This has established these reservoir sections,
the main producing zones in the nearby Rubelsanto Field, as the most likely
appraisal targets to be tested in the upcoming Atzam #5 appraisal well if they
are not tested in the current Atzam #4 well. 
Both Latin American Resources and Schlumberger are highly encouraged by the
logging results seen in the C13 and 14 carbonates and their potential to be a
new commercially productive zone in the Atzam Field to the primary C18 and C19
carbonates sections. 
The Rubelsanto Field has produced over 30 mmbbl to date from eight wells and
is located only 17km to the north east of the Atzam Field, along a structural
fault offset. 
Atzam and Tortugas Fields 
The primary producing formations on the Atzam structure are the C18 through
C19 formations. The Atzam #2 well had initial flow rates of 1,200 bbl/day of
34°API oil which led to new well designs for the Atzam #4 well. The second
well, Atzam #5, will spud following completion of a successful flow testing
program on the Atzam #4 well. 
Recent mapping of the Atzam structure using existing data from previous
operators (Basic, Hispanoil) and MEM, and incorporating reservoir data
acquired since production initiated in December 2007, indicate the possibility
of a structure of comparable size and orientation to that of the existing
Rubelsanto field in Guatemala. To date, the Rubelsanto field has produced +30
mmbbl of oil since its discovery in 1976. The field currently continues to
produce +1,000 bbl/day, 36 years after its discovery. 
In addition to the Atzam structures on Block 1-2005, the Tortugas structure is
a suspended oil field. Originally 17 wells on Tortugas salt dome were drilled
by Monsanto looking for sulphur. One well (T9B) had an oil blowout at approx.
1,500 ft. and most others had oil shows in multiple zones. 
The Atzam and Tortugas Fields have had previous exploration and
development programs with old 2D seismic and previous production wells.

Range Background 
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
  blocks. 
- 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
  exploration wells and will continue with a further seismic and well program
  over the next 12-18 months. 
- Range holds a 25% interest in the initial Smith #1 well and a 20%
  interest in further wells on the North Chapman Ranch project, Texas. The
  project area encompasses approximately 1,680 acres in one of the most 
prolific
  oil and gas producing trends in the State of Texas. Independently assessed 3P
  reserves in place (on a 100% basis) of 228 Bcf of natural gas, 18 mmbbls of
  oil and 17 mmbbls of natural gas liquids. 
- Range holds a 21.75% interest in the East Texas Cotton Valley
  Prospect in Red River County, Texas, USA, where the prospect's project area
  encompasses approximately 1,570 acres encompassing a recent oil discovery. 
The
  prospect has independently assessed 3P reserves in place (on a 100% basis) of
  3.3mmbbls of oil. 
- Range is earning a 65% (option to move to 75%) interest in the highly 
  prospective PUT 6 and PUT 7 licences in Putumayo Basin in Southern
  Colombia. The Company will undertake a 350km2 3D seismic program across the
  two licences and drill one well per licence, as well as looking to re-enter a
  previously suspended well that had a significant historical reserve estimate. 
- Range has taken a strategic stake (19.9%) in Citation Resources Limited 
  (ASX: CTR) which holds a 70% interest in Latin American Resources
  (LAR). LAR holds an 80-100% interest in two oil and gas development and
  exploration blocks in Guatemala with Canadian NI 51-101 certified proved plus
  probable (2P) reserves of 2.3 MMBBL (100% basis). Range also holds a 10%
  interest in LAR.

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
recoverable. 
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.
