January 12, 2009 -- Vancouver, British Columbia -- Happy Creek Minerals Ltd. (TSX-V: HPY, the "Company") is pleased to provide an update on the final 2008 exploration results from its 100% owned Rateria Copper property, located approximately 10 kilometres southeast of Teck Cominco's Highland Valley copper mine, in south central British Columbia, Canada. During 2008, the Company completed nine drill holes and conducted field geology, silt sampling and a 3D induced polarization (3D IP) and magnetic survey covering the majority of the Rateria property. Happy Creek now reports additional drilling, IP and surface rock sample results.
Drilling ResultsDrilling in 2008 has confirmed that the "A" target, identified by the spring 3D IP survey, contains significant copper mineralization including 27.0 metres grading 1.05% copper, 0.019% molybdenum, 5.0 g/t (grams per tonne) silver, and 0.24 g/t gold in R08-05. Approximately 1.2 kilometres further southwest in R08-06, 334.7 metres of 0.071% copper was intersected. The Company believes the A zone is part of a potentially mineralized corridor that is over five kilometres in length.

"Happy Creek has discovered another new zone returning grades that are comparable to those currently being mined at Highland Valley (0.31% copper) and this zone remains undefined and open in extent." stated David Blann, President of Happy Creek. "And we have identified a very large mineralized system having characteristics to host several good deposits".
Drill hole R08-05 is located approximately 200 metres south of R08-01 and R08-03 (*see press release dated September 16th 2008, with additional assays reported here) and together define the central portion of a mineralized corridor that remains open in extent to the south-southwest and northeast. R08-03, collared at R08-01 and drilled in the opposite direction, intersected up to 1.65 metres containing 0.292% copper at the bottom of the hole. In R08-01 and R08-05, three metre intervals containing 1.48 g/t gold, 0.657% copper and 0.88 g/t gold, 13.0 g/t silver and 3.417% copper, respectively, suggest precious metals are positive additions to the potential value of the mineralization.
Drill holes R08-06 and R08-09 are located approximately 1,200 and 400 metres southwest of R08-05, respectively. In R08-06, continuous weak to moderately strong pervasive and fracture controlled k-feldspar, quartz, sericite and argillic alteration is present. Together with 334.7 metres grading 0.071% copper, including 0.158% copper over 3.0 metres at the bottom of the hole, it is thought to reflect the margins of a typical porphyry copper system.
Drill holes R08-02, R08-07 and R08-08 were located approximately 500 metres west of R08-05, and beyond the mineralized corridor, however they did intersect geochemically positive copper values. All holes were drilled at an angle between 55-70 degrees either to the west or east, and glacial till varies from approximately 10 to 20 metres in thickness. Drilling was conducted to test several different geophysical parameters within and surrounding the "A" target, and resulted in a better understanding of geological controls to mineralization.
Rock Sample Results
Recent and on-going mechanized logging-related activity relating to the pine beetle epidemic has exposed several small outcrops within the projected mineralized corridor, with most containing traces to significant copper mineralization.
An outcrop sample located approximately 350 metres south-southwest of drill hole R08-05 returned up to 1.58% copper, 9.0 g/t silver and 0.25 g/t gold. The comparable nature of alteration, mineralization and its location from R08-01 and R08-05, suggests the A zone is over 550 metres in length and remains undefined and open in extent.
Approximately 1.2 kilometres northeast of R08-05, an outcrop returned 2.746% copper, 13.0 g/t silver over 1.2 metres.
Approximately 1.8 and 3.0 kilometres southwest of R08-05, up to 0.20 metres of 13.171 % copper, 71 g/t silver in outcrop and 9.712% copper, 29.0 g/t silver in boulders, occur at the Three Creeks and Moss 4 prospects, respectively.
At the Sho prospect, located approximately 6.0 kilometres south of R08-05, a 15 metre long segment of an extensive shear zone averaged 1.487% copper and 8.4 g/t silver over 4.12 metres in width, and a further 400 metres south, a grab sample returned over 1.0% copper, 8.16 g/t silver and 0.10 g/t gold.
All mineralized zones described above display similar geological and geophysical characteristics and remain undefined and open in extent. In consideration that over 95% of the property is covered by glacial till, the Company feels the frequency and locally high grade nature of these occurrences within a definable corridor that extends for over five kilometres is particularly encouraging.
2008 3D Induced Polarization and Magnetic Survey Results
The 2008 3D IP and magnetic survey results in conjunction with surface samples, drilling and geological mapping support the interpretation of a wide fault, or "corridor", extending between the A zone and through the Moss 4 prospect, a distance of over 5.0 kilometres. The Moss 4 prospect is defined by a 3D IP anomaly approximately 1.4 kilometres in length and 800 metres in width having geophysical features comparable to the A zone. In this area, rare outcrops contain positive geology and alteration along with boulders up to 9.712% copper, 29.0 g/t silver, and this target remains untested by drilling. The expanded 2008 IP geophysical survey has also identified four new targets, including two that are entirely within rocks that host the Valley deposit to the northwest, and remain untested by drilling.
Geological Interpretation
The five kilometre corridor is interpreted to comprise the district scale contact between two dominant phases of the Guichon batholith. Intrusive rocks include eight distinct phases that are quartz diorite, granodiorite and quartz monzonite in composition and medium to coarse grained and locally porphyritic in texture. These rocks are cut by fine grained, porphyritic dikes and sills of quartz and k-feldspar rich composition. In proximity with the major geological contacts, a large scale, northerly trending fault zone, or "corridor" occurs. Similarly, the northerly trending Lornex Fault is located approximately five kilometres to the west and is considered an important feature of the giant Lornex and Valley deposits currently being mined by Teck.
On the Rateria property, mineralized quartz veins and fractures dip gently to steeply, are sheeted to cross-cutting and contain, or are enveloped by, quartz, k-feldspar, biotite, chlorite, epidote, carbonate, sericite/muscovite, hematite and kaolin/clay alteration minerals. Quartz veins from 1.0 millimetre to 0.50 metres in thickness have several textures and contain dominantly bornite and chalcocite (copper sulphides) to depths over 300 metres, with trace molybdenite (molybdenum sulphide) appearing within and near the margins of the zone. Chalcopyrite (copper sulphide) occurs in minor amounts locally within or on the fringe of the previously drilled Zone 1 and the A zone, however, in other areas of the property, it can be more common. Several forms of hematite and other iron oxides occur within and peripheral to the mineralized zones, and minor copper oxide and very minor amounts of pyrite (iron sulphide) occur.
The geology, alteration and mineralization on the Rateria property are interpreted to be consistent with a deeper-seated porphyry copper system and share similarities with other deposits in the Highland Valley.
About the Rateria Property
The Company's 100% owned Highland Valley property now totals almost 13,000 hectares (130 square kilometres) on the southern side of the productive Guichon Batholith. Recently acquired properties contain documented copper prospects and prospective geology thought to be similar to the Rateria, as well as being extensively covered by glacial till that created historical exploration difficulties. Using newer technology and a persistent exploration approach, the Company's goal is to discover new deposits that are viable economic alternatives for the future of this world class mining district in British Columbia, Canada.
