UPDATED 22/1/07

Valuation of Chaco Resources : 'Rule of Thumb' based on 550m shares and using 10% DCF on oil at $60/barrel is 1p on the sp for every 1m barrels (CHP's share) that is proved. Until oil reserves are proven the 1p/1m barrels will be discounted by the market.

Chaco Resources now has three exploration blocks in Colombia and three areas in Paraguay. The next year should see a steady news flow as it establishes the companys transformation from being an exploration company only to also becoming a significant oil production company. Set out below are some of the milestones which should produce announcements and have a positive effect on the share price. All reserves are quoted in recoverable oil assets.



Alea, Colombia :

25% interest in a field currently assessed at holding 38.1m barrels of light sweet crude oil. Drilling of the field by the operating partner, Ecopetrol, was programmed for 2006 to provide early cash flow, but a shortage of drilling rigs, then the rainy season and increased environmental requirements have caused a re-think and it is now expected that this block will be drilled in first half 2007.The proposal to drill a step out well as part of that drilling programme will also provide the opportunity to establish if the estimate of recoverable oil should be increased. (Some estimates suggest the field contains as much as 70m barrels.)

RNS : Updated w/c 30/4//07. Drilling contract should be imminent but actual drilling unlikely to take place second half 2007.



Puerto Lopez, Colombia :

54% Interest in a field containing light sweet crude oil.On 3.10.06 CHP announced that the original TEA area had been extended by the ANH to include further territory which it is expected will greatly increase the potential to find and exploit a structure which may contain as much oil as there is believed to be in Primavera, where Hardman and Co estimate that there is a potential value of 120p per CHP share.

RNS :Updated 22/1/07. Further seismic now obtained and decision not to proceed made because closures too small to be economic and drilling funds earmarked for this project now being retained for use on a more prospective block yet to be announced



Primavera west, Colombia :

55% interest. Two shallow drills in April turned out to be dry. Areas adjacent to this block contain oil (Cana Limon, also in the Mirador basin, the largest oilfield so far, 1.8b barrels) Chaco believe that the area in their block contains the thicker end of a wedge shaped oil-bearing sandstone structure; the area to the east in the neighbouring block has been estimated as containing 400m barrels and the El Miedo oilfield, 8 kms.away has 325m barrels. ANH Contract signed w/c 8/5/06 (1 week sooner than forecast). GED are drilling their neighbouring block in February 2007; two of their targets may contain oil deriving from Chaco's area so some earlier cash flow may result.

RNS : The drilling programme has now been completed but the company has yet to say whether the block will be explored further or abandonned.

New block announced in April known as Tigra in the Magdelana Basin. CHP has a 48.75% interest. Believed to be very promising but company is doing 3-d seismic over the next 18 months with drilling projected in the following 16 months. (Timescales seem to be set to allow a lot of room for delays or speeding up if progress is easier than anticipated)



Curupayty Block, Paraguay :

1.39m hectares in north, close to Bolivia. Two wells previously drilled and both showed oil.

RNS : Expect partnership with larger producer.



San Pedro Block, Paraguay :

1m hectares in south-east. Previous drilling showed oil.

RNS : Expect partnership with larger producer.



Parana Basin, Paraguay :

Canindeyu block covering 1,789,000 hectares. Bordering Brazil. Oil field on Brazilian side already drilled. Chaco also expect to find oil and, at a deeper level, considerable quantities of gas. Chaco has obtained valuable historic seismic for re-evaluation.

RNS : Presidential Decree received 2/11/06.. Petrobras has announced its intention to increase substantially its effort to exploit Paraguay's hydrocarbons and has announced a farm-in on CDS's adjacent block. Possibility that they or another major will do likewise with CHP



Corporate Activity :

CHP obtained an independent evaluation of their exploration assets by Hardman and Co., during July 2006.This is updated monthly. As Chaco Resources line up their assets ready for production they may attract a bid. There are also other actions that the mgt. could take to increase the Chaco's asset share subject to negotiation since the position of the Colombian state oil company, Ecopetrol, is believed to be under review. Other actions could be taken which would have the attraction in bringing more resources to bear on a quicker timeframe plus help streamline the management of their assets. De-merging the Colombian and Paraguayan assets at an appropriate time might hold out some advantages to shareholders at some stage.
Last Placing announced at 15.1p per share on 18/5/06.
Chairman and FD bought shares 8/06 and the Chairman recently exercised his option on further shares which would suggest that he regards the share price to be going north from here on.
Updated 22/1/07.




Here are some dates for your diary courtesy of KJKelly, who posts on ADVFN

1. Curupayty - complete reprocessing of seismic by end July 06
2. Curupayty - complete interpretation of seismic by end August 06
3. Curupayty - decide whether to proceed to drilling or proceed with a farmout campaign - end September 06
4. Platanillo - commence re-entry of Alea 1 early in 1st quarter 2007
5. Primavera - two structural targets will be selected from 10 potential targets for drilling commencing Feb. 2007.
6.Hardman updates should now happen monthly.

Chaco, its gone very quiet,any good news in the offing.

Next week is likely to produce quite a lot of news on various fronts; current weakness in sp and the way the trades are going through at the moment smells of manipulation ahead of that. Cannot say more at the moment.

It looks to me that we are heading for a soggy end to the week, which implies that some of the small caps (especially) will be marked down ..... depending on how brave one feels, that could be a buying opportunity ..... for myself, i am trying to keep my fingers off any buy or even sell (short) buttons, though i am tending towards the view that another big sell off may be in prospect ..... this is based as much as anything on the markets' (Dow in particular) inability to pierce the 11250 ceiling ..... it has now tried and failed several times

The interest rate rise today will also affect sentiment for the market as a whole.
2517

Give us a clue sharesure, is it likely to be good news?

looks like boe want a recession and they are going to get it. thats for sure .

chp gone v quiet.

this sector is v poor atm. need to be producing not speculating.

Oil price on the up again....
The sooner we can prove-up some the better.

oil price moving a dollar or three in either dirtection will not have any impact on the likes of CHP until they actual find the blak stuff or even start getting it out of the ground ...... this latter is likely to be at least 6/12 months away or even longer

Cynic, think you might be proved wrong on the getting oil out of the ground prediction unless you mean full production. I think that you may find that some recent additional personnel helping the operator on one of CHP's Colombian blocks intends to bring forward the drilling programme.

surely proving the oil is actually ther is one thing, and more than an excellent start, but surely there is a considerable time lag between that and starting to ship the damn stuff out

Wait for the update that is coming out followed by the AGM; think that you will then have a clear picture of their progress.

Do we have a date for the AGM yet ??

I hear that the AGM date is soon to be announced

Cynic

Why look at a company pre-production if you don't like the build-up process?
You ole cynic you........lol

because dibbles, i held this share for quite a long time, got out at a modest profit when i went 100% cash, and shall almost certainly buy back in in due course ...... with the current market volatility, i see no hurry just yet

mph,,we have a troll on your board over on advfn,please remove,,,thanks.

Well done so far Trotting-keep it up.

Chairman's Statement



Your Company continues to make solid progress with its plans to become an oil
and gas producer, targeting some very promising oil and gas prospects in South
America and establishing itself as a serious oil exploration company in the
process.



Details of the work programme are contained in the Business Review within the
forthcoming Annual Report, although it should be regarded as an update on work
in progress. Since our year end of 31 March 2006 much has been achieved.



The most important achievement is that we are delivering on our promise of
re-focusing the business on oil and gas at a time when the world oil price is
close to an all-time high. Needless to say, if we were embarking on this course
today, the cost of entry would be considerably higher, and the opportunities we
have been able to seize would probably not be available on the same attractive
terms.



The acquisition of well located exploration blocks in Colombia, a world-class
oil country, and in Paraguay, a potentially hydrocarbon-rich country, have been
our first critical steps forward. In Colombia we now have interests in three
blocks, thanks largely to a strategic joint venture formed with the
Colombian-based consultancy, Expet S.A. This relationship has given us
all-important exposure to eyes and ears on the ground: local knowledge that lies
at the heart of most successful businesses. In Paraguay, where we have a very
resourceful regional office, the exploration programme is advancing although is
still at an early stage. We plan to introduce farm-in partners for the
second-phase of work. The recent news that Petrobas plan to explore in the Chaco
region of northern Paraguay is, of course, a significant development with
respect to the possibility of finding hydrocarbons in the region.



In Colombia, we expect to be drilling later in calendar year 2006 on the
Platanillo Block in which we are earning a 25% interest . A worldwide shortage
of drilling rigs has impacted exploration to date. However, the delays we have
endured are easing and drill rigs are now becoming available. This block
contains the Alea well, which flowed 533 barrels of oil a day in 1988, and based
on which there is every reason to be optimistic that an oilfield of considerable
significance to the Company can be expected.



In the Puerto Lopez Oeste Block, in which we are earning a 54% interest,
re-processing of seismic data started in the final days of the year under
review. Initial feedback from the technical analysis indicates the presence of a
Mirador fault play lead. More work is required but this is a very positive
development, as the area is known for its fault plays; the nearest being the
Apiay Field located about 80 kilometres west of Puerto Lopez, containing an
estimated 100 million barrels of oil. In the autumn the shooting of a minimum of
100 kilometres of fresh two-dimensional seismic is scheduled to further advance
our plans to drill this block.



The Primavera Block, in which we will earn a 55% interest, was acquired after
the year end and features a series of undrilled leads and structures that had
previously been mapped. Drilling close to this block has revealed a number of
oil shows, but most early wells do not appear to have been drilled within
structural closure. It is expected that two targets will be selected for
drilling late in 2006.



Commencement of drilling will mark a milestone for the Company, with at least
four wells planned for our blocks in Colombia before the end of the current
financial year. It is significant to note that this work is part of a rapid
acceleration of oil exploration in Colombia, one of the most business-friendly
countries in South America. Many of the world's major oil companies, including
British Petroleum and Occidental, are active there.



Management continues to look for opportunities to expand the asset base and,
given our excellent local partners, and a good working relationship with
government agencies, we can look forward to this objective being achieved.



Much of the success of the past year must be attributed to the small, but
excellent, management team assembled in the Company. On behalf of the Board I
extend thanks for their work.



During the year we said farewell to two Directors. Tom Elder, our deputy
chairman, stepped down after many years of service, as did Lee Graber. To both I
offer heartfelt thanks for their work. Since 31 March 2006 we have appointed
Nicola Brookes who takes on the role of Finance Director. We are very pleased
that Martin Groak continues to serve on the Board as a Non-Executive Director:
he has given many years of excellent service to the Company and his continued
input and knowledge is invaluable.



As a final observation it is worth looking back, however briefly, on how the
Company has evolved. It is now poised for its most significant development with
the commencement of a busy drilling schedule in Colombia, advancement of the
early work in Paraguay, and a continued search for additional opportunities. The
year ahead should be an interesting one.
