Underworld’s Metallurgical Tests Show Excellent Results

Underworld Resources Inc. has received non-optimized initial metallurgical testwork from the Golden Saddle and Arc gold deposits, at the White Gold property. These results returned excellent gold recoveries from the Golden Saddle zone.

At the Golden Saddle zone, a total of 23 samples from six 2008 drill holes averaging 6.60 grams per tonne (g/t) gold were analyzed by bottle roll cyanide leach methodology. All samples returned an average 85.5-per-cent recovery, ranging from 65.7 to 93.7 per cent. Samples included near-surface oxidized material, partially oxidized, and unoxidized material. Unoxidized and partially oxidized mineralization returned higher recoveries, averaging 87.7 per cent, with oxidized mineralization averaging 73.6 per cent. Additionally, higher-grade individual samples, over 10 g/t gold, typically displayed slightly lower recoveries averaging 83.7 per cent. This is potentially due to reduced leaching with coarse gold, which could possibly be amenable to gravity separation to boost recoveries.

Surface oxidation due to weathering at Golden Saddle ranges from 10 to 40 metres, averaging about 20 metres below surface. Local partial oxidation occurs near postmineralization fault zones. The majority of mineralization encountered to-date at Golden Saddle is unoxidized.

At the Arc zone, a total of 17 samples from two 2009 drill holes averaging 2.05 g/t gold were analyzed from the two styles of mineralization: graphite poor (WD09-39) and graphite rich (WD09-37). All samples averaged 51.2-per-cent recovery, however, gold mineralization without graphite averaged 81.7-per-cent recovery. The presence of preg-robbing graphite resulted in poor recovery, averaging 4.6 per cent. Graphite often occurs within sediment-hosted gold deposits, and can be removed using various metallurgical processes.

The Golden Saddle deposit is located 1,000 metres north of the Arc Deposit. The two deposits display different styles of gold mineralization, geochemistry and host rocks. Golden Saddle occurs within metavolcanic and intrusive rocks, with gold mineralization associated with pyrite veining, silicification, quartz breccias and stockworks, whereas the Arc Deposit is hosted with metasedimentary rocks, and is typified by hydrothermal breccias and silicification.

The different styles of mineralization and gold recoveries at Golden Saddle and Arc are due to varying host rock lithologies. The principal host rock at Golden Saddle was a granitoid that has been metamorphosed to an augen gneiss. Arc mineralisation is hosted by sediments which now outcrop as quartzite.

Underworld has initiated an optimized metallurgical testing program with Inspectorate PRA Metallurgical Division of Richmond BC, with results expected during the latter part 2009. Samples from the multiple styles of mineralization at the White Gold Property will be analyzed for cyanide leach, gravity recovery and Bond Work Index. Optimization studies such as gravity recovery have the potential to boost overall metallurgical recoveries.
Underworld is currently awaiting assay results from an additional 32 holes at the White Gold Project. At Golden Saddle, Mineralization remains open to expansion along strike to the northeast and at depth.

Quality Assurance

Underworld has implemented a rigorous QA/QC program at the White Gold Property using best industry practice. Elements of the program include: chain of custody of samples, insertion of standard and blank samples, and check assays. Drill core is sawn in half and shipped in sealed bags to ALS Chemex Laboratories in Vancouver, B.C. Check assays are being undertaken by Acme Laboratories, Vancouver. Bottle Roll cyanide-leach analysis from the 2008 samples were performed by Alaska Assay Labs in Fairbanks, AK, and for 2009 samples by ALS Chemex Laboratories in Vancouver, B.C.

The ongoing 2009 Exploration Program is directed by Adrian Fleming, M.A.I.G, RPGeo, M.Aus.I.M.M., President of Underworld Resources and a Qualified Person as defined by NI 43-101. Mr. Fleming prepared, and approves of the content of this release.

Pacific Ridge Acquires Mariposa Property in South Klondike

Pacific Ridge Exploration Ltd. has added the Mariposa gold property to its portfolio of four gold targets already held in the Yukon’s South Klondike region.

The Mariposa property, consisting of 203 mineral claims, covering approximately 50 square kilometres and located approximately 50 kilometres east of Underworld’s Whitegold discovery, lies within a regional major northwest trending structural corridor hosting gold and copper deposits.

The Mariposa claims cover a 14-kilometre length of a geological setting analogous to the Whitegold style of gold mineralization. The Mariposa vendors, who have been exploring the property for the past 10 years, have defined an open-ended seven-kilometre length of altered quartz mica schist favourable for hosting gold mineralization within the Klondike region. Initial soil sampling at the western exposed end of the host schist has defined an open-ended two-kilometre-long gold soil anomaly contoured above 20 parts per billion gold. Preliminary soil sampling by the vendor has also outlined a second open-ended gold target, measuring a square kilometre and overlying nearby intrusive rocks. There also appears to be a relationship between aeromagnetic anomalies and indications of gold mineralization. All streams draining the property are known to contain placer gold, of which Scroggie Creek has had a long history of placer gold production which continues today. The placer miners recovery of hackly gold nuggets may suggest the presence of nearby lode gold sources.

During the balance of this season, Pacific Ridge will continue with geochemical surveys at the Mariposa property to further define existing gold anomalies in preparation for next season’s plan for trenching followed by drilling.

On Pacific Ridge’s Goldcap, Stewart-Polar, Eureka and Moose properties, geochemical sampling and geological mapping are in progress.

Subject to receipt of regulatory acceptance, Pacific Ridge will make an initial payment of $20,000 and 250,000 shares. Pacific Ridge will have the option to earn 100 per cent over the next five years by making payments in the aggregate amount of $120,000 and two million shares and minimum exploration expenditures of $600,000. The vendors will also be entitled to receive an additional one million shares upon a production notice having been made plus an additional one million shares upon commencement of commercial production. The vendors will also receive a 2-per-cent net smelter royalty from production, of which 1 per cent can be bought down by Pacific Ridge for $1-million.

As previously reported, Pacific Ridge has received $320,000 from the closing of a private placement offering of flow-through and non-flow through units.

Kaminak Stakes New Ground in Yukon

Kaminak Gold Corp. has staked 210 additional claims (4,250 hectares) in the emerging White gold district of the Yukon. The newly acquired claims tie on to the southwest corner of the company’s Coffee property and extend south and west to the company’s Cream property. Kaminak now holds title or has title pending to over 13,000 hectares (32,000 acres) in the White district.

These claims were staked in order to cover the possible extensions of newly defined soil anomalies on the Coffee property. Kaminak has now received results for over 2,250 soil samples from across the property, resulting in the definition of eight separate gold-in-soil trends occurring over a length of 11 kilometres. Several of these trends remain open to expansion. From west to east these trends are named: Espresso, Kona, Latte, Supremo, Double Double, Mocha, Arabica and Java. With the exception of Supremo, all of these trends were identified in this year’s soil sampling program. Of note, the Latte trend extends over 800 metres long by 50 to 100 metres wide, averages 603 parts per billion Au along the entire length and is open to the west. Maps showing the location and intensity of these trends are now available on Kaminak’s website.

Kaminak is currently awaiting rock assays from 494 chip samples taken from shallow trenches which were dug over priority gold-in-soil anomalies at the Supremo and Latte trends. Results are expected in the coming weeks. To date, only 50 rock assay results from trenching have been received by Kaminak successfully identifying gold surface mineralization on the Supremo trend and grading 2.3 grams per tonne Au over 21 m. Additional trenching is continuing at the Kona and Espresso trends.

Once all trench results have been received, Kaminak will proceed with an initial diamond drill program over priority targets in the spring of 2010. Expected winter weather conditions will force the current field program of trenching and soil sampling to be completed before the end of September.

A total of 2,250 soil samples have been analyzed so far during the 2009 season and 81 of these samples yielded results greater than 75 ppb Au (highest threshold). Over all, results ranged from background (less than 15 ppb Au) to a high of 3,156 ppb Au or 3.156 g/t Au. Gold-in-soil anomalies are also associated with high arsenic (As) and antimony (Sb). Two hundred twenty five samples yielded arsenic values greater than 100 parts per million As (range one to 967 ppm) and 22 samples assayed greater than eight ppm Sb (range nil to 117 ppm).

Ashburton Ventures Finds 600+ Metre Gold Anomaly in White Gold District

Ashburton Ventures Inc. has released the results from the late July soil sampling program on its Valley prospect in the Yukon near Underworld’s White Gold property. The Ashburton claims are adjacent to ground held by Underworld and 10 kilometres north-northeast of the company’s Golden Saddle discovery.

Reconnaissance soil lines were surveyed across the Valley project area with samples collected every 50 metres on lines spaced 300 metres apart. The lines roughly paralleled the dominant trend of the geography while crosscutting the dominant trend of the geology. Multiple gold soil anomalies, apparently paralleling the mapped geology, were detected on three adjacent soil lines with analyses ranging up to 90 parts per billion gold.

A second phase of soil sampling has been initiated at the Valley prospect to triple the sampling density to 50-metre centres on lines spaced 100 metres apart in the areas of the anomalies. Samples will be collected from eight new lines with the intention of better delineating and hopefully expanding on the 600 metres plus of apparent strike already identified by the anomalous samples.

Pending results of the follow-up soil sampling, a trenching program followed by a drill program are anticipated for next spring.

Work on the Ashburton ground is being directed by Dr. David Hedderly-Smith, PhD, PG. Dr. Hedderly-Smith has done work in similarly aged rocks in east-central Alaska, 100 kilometres to the northwest, off and on since the 1970s, and is a qualified person as defined by National Instrument 43-101. He has approved the information in this press release.

Stina Completes Work Program, Awaiting Results

Stina Resources  is pleased to announce that it has completed a work program on the Kodiak property in the Dawson Mining District of the Yukon Territory. The Kodiak property claim block consists of 152 claims covering 30 square kilometres or 6400 acres and ties on to the southern side of Underworld White Gold Property. The Kodiak claim block also straddles Thistle creek which was the richest placer gold-producing creek in the area given up more than 63,000 ounces of placer gold since the turn of the century.

The recently completed work program consisted of 1,800 soil samples collected from the upland areas surrounding the silt anomalies.

of Ryanwood Exploration Inc (REI) was the vendor for the Kodiak property as well as for Underworld’s White Property and re-evaluated the Geological Survey of Canada database for similar positive indicators for white-style mineralization on the Kodiak property. The GSC silt survey of the Thistle area identified anomalous gold and arsenic levels in silt samples collected from streams that drain Kodiak Property. The presence of elevated gold and arsenic values suggests potential for mineralization similar to that identified by Underworld Resources.

Considering that Underworld and other junior mining companies operating in the White District have had considerable success using soil geochemical surveys to pinpoint areas of gold mineralization management is optimistic the initial program will identify targets that warrant follow up work. In the event that targets are defined, the Kodiak Property could easily be fast tracked because there is an access road and airstrip along Thistle Creek.

The Company entered into an option agreement with Ryanwood Exploration Inc. (“REI”) for a 100% interest in the Kodiak property on July 8, 2009.

Underworld Resources Increases Land Holdings

Underworld Resources Inc. has significantly expanded its land position in the White gold district through acquisition and additional staking. The majority of this new ground is contiguous with the original claim group hosting the Golden Saddle and Arc gold discoveries.

The majority of new claims were staked by Underworld following the recent gold discovery on the Golden Saddle deposit, located 90 kilometres south of Dawson, the location of the famous Klondike gold rush.

In total, Underworld now holds title to or has title pending on 2,907 quartz mining claims for a total area of 589 square kilometres, doubling the size of the land package.

The 100-per-cent-owned White gold property hosts a significant discovery at the Golden Saddle deposit. Underworld’s continuing drilling program currently has assays pending for a further 23 drill holes at the Golden Saddle deposit and has increased the size of the current drill program at the White gold project to 25,000 metres.

These new claims were staked based on regional geology and geochemistry, exhibiting favourable similarities to the Golden Saddle and Arc discoveries at White Gold.

Additionally, the company has amended the original agreement with Shawn Ryan to acquire a 100-per-cent interest in an additional 646 claims in the White gold district. As compensation for these claims, Underworld will pay the following: Reimburse Mr. Ryan $250 per claim, Issue to Mr. Ryan 200,000 common shares of Underworld on the date that is five business days following the date of acceptance of the TSX Venture Exchange of the agreement, Issue an additional 200,000 common shares of Underworld on or before Aug. 12, 2010, and issue an additional 200,000 common shares of Underworld on or before Aug. 12, 2011, Pay Mr. Ryan $1 per ounce for any ounces of gold on the additional claims that are categorized as reserves or measured or indicated resources in a National Instrument 43-101 technical report publicly distributed by Underworld (payable within 90 days of the date the report is published by Underworld) or at the time of the acquisition of at least 50 per cent of the issued and outstanding voting or equity securities of Underworld by a third party based on an internal technical report prepared by Underworld (payable within 90 days of the acquisition).

Some claims recently acquired are subject to a finder’s fee.

The company is currently evaluating its extensive additional landholdings with reconnaissance mapping, sampling and prospecting. Underworld has carried out systematic ridge and spur soil sampling plus selective grid soil sampling on several of these new areas.

The continuing 2009 exploration program is directed by Adrian Fleming, MAIG, RPGeo, MAusIMM, president of Underworld Resources and a qualified person as defined by NI 43-101. Mr. Fleming prepared and approves of the content of this release.

Cariboo Rose Outlines Gold Geochemical Anomalies Along a 4 Km Trend in White Gold District

Cariboo Rose Resources Ltd. (TSX-V: CRB) and Alder Resources Ltd. (TSX-V: ALR) are pleased to report on ongoing exploration on the Canadian Creek Project in the Whitehorse Mining District of the Yukon Territory 160 km south of Dawson City. The property is also 50 km southeast of Underworld Resources Inc.’s (TSX-V: UW) White Gold project and approximately 25 km southeast of Kaminak Gold Corp.’s Coffee property.

A soil sampling grid has been cut and sampled, and the analytical results indicate a series of gold and arsenic anomalies across the entire 4.0 km width of the grid. The anomalies are defined by 20 ppb contours and individual anomalies are up to 1.5 km in length. At a 50 ppb gold threshold the largest anomaly is 1.2 km long and 300 m wide. The anomalies show strong linear trends from east-west to northeasterly. Previous sampling of float in one of these anomalies returned 6.6 g/t gold and 51 g/t silver from a piece of quartz-arsenopyrite vein. An induced polarization (IP) geophysical survey was also completed over the grid and outlined several anomalies that show the same general trend as the soil anomalies.

A separate gold geochemical anomaly, 3.0 km southeast of the gold-arsenic anomaly and adjacent the Casino Deposit presently being explored by Western Copper Corporation, was defined during previous exploration on the property and received some follow-up. An old trench (9076C) in the middle of this large anomaly was reported to have returned 1.69 g/t gold across 10 m. The trench was re-sampled with 5 m chip/panel samples and returned 45 m of 0.33 g/t gold with an interval of 10 m grading 0.93 g/t in the centre of the trench. A diamond drill hole completed in 1993 located within this same anomaly intersected 150 m grading 0.49 g/t gold, including 44 metres grading 0.71 g/t.

Alder has contracted Kluane Drilling, based in Whitehorse, to undertake a drilling program on the property. Kluane is presently drilling for Western Copper on the adjacent Casino Deposit and this provides a tremendous logistical and cost advantage to the project.

Alder can earn a 60% interest in the Property by completing a schedule of cash payments (totaling $250,000) to Cariboo Rose, issuing a total of 250,000 shares to Cariboo Rose, and fulfilling designated exploration expenditures on the property totaling $2,500,000 by June 18, 2013.

G.L. Garratt, P. Geo., who is a qualified person within the context of National Instrument 43-101, has read and takes responsibility for this news release. Bob Johnston, P. Geo., also a qualified person within the context of National Instrument 43-101, is supervising the project work in the field. Analysis was performed by Acme Analytical Laboratories, a certified facility in Vancouver, BC, using multi-element (ICP-MS) Aqua Regia Digestion (1D) procedures, with gold and silver values determined using fire assay procedures.

Underworld Step-out Holes Expand Golden Saddle Zone, Including 3.13 g/t Au over 100.4 meters

Underworld Resources  is pleased to announce additional results from the ongoing drill program at the White Gold Property, Yukon. To date, Underworld has completed 22,000 meters of drilling over 84 holes during the 2009 exploration program.

Highlights of the most recent assays from the Golden Saddle zone include:

Hole ID

Weighted avg. grade
(g/t Au)

Length (m)

WD09-64

3.13 g/t  Au 

100.40  meters

WD09-69

3.40 g/t  Au

76.90  meters

WD09-70

3.51 g/t  Au 

50.03  meters

Results to-date continue to demonstrate excellent continuity of near-surface gold mineralization at the Golden Saddle Zone. The deposit remains open to expansion to the east and north. Drill hole WD09-64 is a step-out hole to the northeast, and intersected 100.4 meters averaging 3.13 g/t, including 19.5 meters averaging 6.70 g/t Au. This is the northeastern most hole for which assays have been received to date, with assays pending for additional holes completed along strike and down-dip. The intercept in WD09-64 is 75 meters down-dip from WD09-56, which intersected 55.9 meters averaging 1.50 g/t Au, and 110 meters down-dip from WD09-47, which intersected 31.1 meters averaging 9.2 g/t Au. Four additional drill holes on approximately 50 meter centers have been completed down-dip from WD09-64, with assays pending.

WD09-069, which intersected 76.9 meters averaging 3.40 g/t Au, including 41.0 meters averaging 5.44 g/t Au, and WD09-70 which intersected 50.5 meters averaging 3.51 g/t Au, including 37 meters averaging 4.04 g/t Au are infill holes. Infill and step-out drilling is being completed on 50 meter intercept centers along strike and down dip. These holes demonstrate the excellent continuity of grade and thickness at Golden Saddle.

The objective of the current drilling at Golden Saddle is to continue to expand mineralization along strike and down-dip, and to complete a NI 43-101 compliant resource estimate. The Company is targeting near-surface mineralization potentially amenable to open pit mining, as well as deeper extensions potentially amenable to bulk underground mining methods. During 2009, 54 holes have been completed at the Golden Saddle Zone, with assays currently pending for 21 holes.

Infill and step-out drilling has been completed on 100 meter centers at the Arc Zone, located about 1,000 meters south of Golden Saddle. At the Arc Zone, 19 holes have been completed to-date, with assays pending for an additional 10 holes. Drill holes WD09-57, 58, 65, and 67 have extended the Arc zone to the West-Southwest of WD08-17 (29.0 meters averaging 1.47 g/t Au). Underworld has completed four regional holes at Minneapolis Ridge, and three regional holes have been completed at the Donahue Zone. Drill hole DN09-01 at the Donahue target, located 2,500 meters south of Golden Saddle encountered anomalous, near surface gold mineralization within soil, rock grab, and trench samples, similar in style to the Golden Saddle. Assays for two additional holes at Donahue are currently pending.

Underworld is currently drilling regional targets at the South Donahue and McKinnon showings, located four and six kilometers southeast of Golden Saddle, respectively. Three drill rigs are currently in use on the project and it is anticipated that a total of 25,000 meters of core drilling in approximately 115 drill holes will be completed during the 2009 program. A complete table of assay results from the 2009 White Gold Drilling Program, as well as cross-sections, and drill plan maps will be available shortly at www.underworldresources.com.

Intrusive-related gold mineralization at the Golden Saddle Zone is preferentially hosted within metamorphosed felsic intrusive units, as well as felsic and mafic metavolcanic rocks. Gold mineralization is associated with quartz veins, stockwork and breccia zones, as well as pyrite veinlettes and disseminations. The alteration assemblage includes pervasive K-spar, carbonate, sericite and silicification. The main mineralized zone at Golden Saddle strikes to the northeast, with a gentle to moderate dip to the northwest. Mineralization remains open to expansion along strike to the northeast and at depth.

Northern Tiger Completes Geophysical Program and Drilling

Northern Tiger Resources Inc. has completed the expanded 2009 drill program at its Sonora Gulch gold-silver-copper property. In addition, a 1,437 line-kilometre airborne geophysical survey was completed over most of the Company’s Dawson Range properties, and ground magnetic and Induced Polarization (IP) surveys were completed over a potential Minto-style target on the Company’s DAD property.

Northern Tiger drilled 12 diamond drill holes totalling 2,455 metres during the 2009 exploration season. The program focused on the Nightmusic Zone, where 2008 drilling returned a 26.6 metre intercept grading 4.96 g/t gold, 11.9 g/t silver and 0.23% copper (see News Release dated October 28, 2008). The Company’s drilling contractor, Kluane Drilling Ltd., completed 11 of the drill holes to an average depth of 216 metres, while one of the holes was abandoned at a depth of 74 metres due to difficult drilling conditions. Northern Tiger also completed extensive surface exploration work at Sonora Gulch, including property-wide soil sampling, rock sampling, geological mapping, and prospecting.

Northern Tiger recently completed a low-level, multi-sensor airborne geophysical survey over its Sonora Gulch, Bond, Mel, Del, Led, Birman and Korat properties. The surveys were flown by Precision GeoSurveys Inc. of Vancouver, BC. A total of 1,437 line-kilometers were flown at a 100 meter line-spacing. A high-sensitivity magnetometer system will assist in interpreting bedrock units, structure, and alteration. The radiometric system consisted of a multichannel spectrometer with state-of-the-art design to map rock units and alteration patterns.

A ground geophysical program was also conducted at Northern Tiger’s DAD property by Aurora Geosciences Ltd. The survey covered a target considered prospective for mineralization similar to that being processed at Capstone Mining Corp.’s nearby Minto Mine. Northern Tiger has a strategic alliance with Minto Explorations Ltd., a wholly owned subsidiary of Capstone Mining Corp., to facilitate exploration for this style of deposit in the region.

Results of the 2009 exploration drill program, geophysical surveys and surface exploration work are pending.

“We are extremely pleased with the efficiency of our 2009 program”, says Greg Hayes, President of Northern Tiger. “The entire program ran very smoothly thanks to the efforts of our staff and through close cooperation with our major suppliers. We are currently demobilizing our Sonora Gulch camp, and are looking forward to receiving and interpreting the results of all of our 2009 exploration initiatives.”
