• recommended follow-up includes structural mapping followed by further drilling with deeper holes

Location & Ownership:

• 100%-owned (subject to 2% NSR)
• 95 km northeast of Dawson City, Yukon (30 km east of the Dempster Highway)
• 220 claims covering approx. 4,074 hectares (10,067 acres)

Exploration Target:

The target is an intrusion-related gold system (IRGS).  The property lies within the highly prospective  Tintina Gold Belt, which constitutes an arcuate belt of gold deposits that are directly associated with mid Cretaceous intrusions extending from Donlin Creek in Alaska, through the Fairbanks District (including Fort Knox; 169 Mt @ 0.93 g/t Au), Pogo and across the Yukon border where it incorporates the Tombstone Gold Belt; a 200 km long belt of gold deposits associated with the Tombstone plutonic suite, with examples including Dublin Gulch (66 Mt @ 0.92 g/t Au) and Brewery Creek  (10 Mt  @ 1.4 g/t Au).

Mineralization at Heidi has strong similarities to occurrences such as Mike Lake and Scheelite Dome (Yukon) where the gold mineralization occurs as vein and replacement bodies within the metasedimentary rocks outboard of Tombstone intrusions. 

A new discovery was made at Mike Lake (15 km southwest of Heidi) in 2007 with 89.3m grading 0.61% copper, 1.38 g/t Au and 13.6 g/t Ag obtained from the only drill hole testing the zone. Results from Scheelite Dome include 2.21 g/t Au across 10.1m, 1.03 g/t over 20.3, 7.09 g/t Au across 6.4m, and 24.42 g/t Au over 1.7 m in drilling. 

The buried intrusion at Heidi has potential to host Fort Knox/Dublin Gulch style intrusion hosted mineralization.

Deposit Potential: Intrusion-Related Gold System ("IRGS")

Heidi lies within the prospective Tintina Gold Province (TGP), specifically the Tombstone Gold Belt; a 200 km long belt of gold deposits directly associated with mid Cretaceous age intrusions of the Tombstone plutonic suite. Based on the results from an airborne magnetic survey and surface geology a large Tombstone-type intrusion (6 km in diameter) has been inferred to underlie the northern portion of the property.

The property is underlain by Proterozoic metasedimentary rocks of the Hyland Group intruded by dykes of the Tombstone plutonic suite. Mineralization consists of stratabound gold-bearing pyrite-arsenopyrite replacement zones in carbonate-rich horizons and related quartz-sulphide breccia veins peripheral to a buried intrusion, similar to the setting at Mike Lake and Scheelite Dome, Yukon Territory.

Exploration results to date:

• mineralization traced along surface for a distance of 2 km
•  trench sampling returned values ranging from 1 to 7 g/t gold over 1 m intervals and grab samples assayed up to 19.9 g/t gold
• drilling in 2006 and 2007 intersected gold mineralization in 16 of 21 holes over a 1 km strike
• diamond drill results include  2.09 g/t Au and 9.5 g/t Ag over 4 m, including 4.04 g/t Au and 18 g/t Ag over 2 m with anomalous arsenic (As), antimony (Sb), and bismuth (Bi)
• subsequent to the 2007 drill program, Logan Resources conducted a helicopter airborne magnetic survey, which provided more detail of the underlying geology

Follow-up:

• new drill targets have been delineated, which require pre-drilling confirmation through structural mapping 
• drilling at Heidi requires the targeting of mineralization within the fold noses where structural thickening of the replacement zones can occur.  Deep holes are necessary to target the buried intrusion

Property History:
 

Late 2007: A helicopter airborne magnetic survey outlined new targets for the next phase of drilling.

2007: An additional 19 diamond drill holes totaling 2,686 m (8,812 feet) were completed by Logan to test coincident IP, magnetic and gold geochemical anomalies. Results included 1.51 g/t Au and 14.3 g/t Ag over 3 m in HDI 07-07.  The combined 2006 and 2007drilling intersected gold-silver mineralization in 16 of 21 holes covering a 1 km strike extent, with anomalous arsenic (As), antimony (Sb), and bismuth (Bi).

2006: Two diamond drill holes totaling 425 m (1,394 feet) completed by Logan.  Hole HDI-06-02 intersected a 26 m mineralized zone containing 2.09 g/t Au and 9.5 g/t Ag over 4 m, including 4.04 g/t Au and 18 g/t Ag over 2 m in HDI 06-02.

2005: Review of 2003 geophysics data by a geophysical consultant and property evaluation by an independent geologist, funded by Logan.  Additional IP geophysics and a 1,600 m diamond drill program was recommended, to be followed by a 7,600 m drill program.

2004: A due diligence site examination was completed by Logan. Sampling confirmed the previous trench results and grab samples assayed up to 19.9 g/t gold.

2003: Acquisition by Logan who funded a geophysical program consisting of magnetic, IP and test HLEM across an area of coincident gold and arsenic soil geochemical anomalies.

2002-2003: Acquisition by staking by Mr. Shawn Ryan (a prominent Dawson City, Yukon prospector).

1996: Homestake completed prospecting, geological mapping, soil sampling (defining significant gold-arsenic-antimony anomalies) and trench re-sampling (yielding 1 to 7 g/t Au values over 1 m widths). A 2,000 to 3,000 m diamond drill program was recommended, but Homestake carried out only minor mapping and geochemical sampling in 1998, allowing the property to lapse in October 2001.

1995: The Heidi property was staked by Homestake Canada Limited, to cover a new gold showing discovered while investigating a magnetic anomaly. The anomaly was inferred to be caused by a blind Tombstone intrusive plug with a strong, coincident gold-arsenic-antimony stream silt anomaly. The showing consists of pyrite, arsenopyrite and stibnite/jamesonite replacing limestone. Values up to 2.93 g/t gold over 1 m were obtained from the small scale trenching program that year.
