The document summarizes geological information about map sheet 105O03 in the Yukon Territory of Canada. It describes the regional geology, rock units, mineral occurrences, and sample analyses in the area. Sedimentary rocks dominate, and the area contains deposits of silver, lead, zinc, and copper. Sample analyses of silver, lead, and zinc show anomalous concentrations indicative of sedimentary exhalative (SEDEX) deposits. Faults in the rock units likely aided in the formation of these shale-hosted metal deposits.

2. Introduction
 Yukon(The great River) Territory is one of the three smallest
territories in Canada, Locates in north west of Canada , and it’s
Capital city is White Horse .
 Boarders :
• East :Northwest Territories
• West :Alaska
• North: Arctic ocean
• South : British Columbia
 The industry is mining and account’s for 30% of the economy
 The Yukon contains many undeveloped mines of zinc , lead , silver,
copper and iron.
 Sedimentary rocks are the main type of the Yukon territory

4.  Over the last 190 million years , the area was affected by
folding , faulting , metamorphism and uplifting which ended
by stratigraphy of sedimentary units above a stable geological
basement.
 The Yukon is classified into five mineral areas :
• Peel (river) class 1 notification area
• Ross river class1 notification area (105O03)
• South western Yukon class 1 notification area
• Watson lake class1 notification area
• Southern Yukon class 1 notification
area(http://mapservices.gov.yk.ca/Mining/WebMap.aspx)
 (Class 1 means class 1 exploration program)
In this presentation , I will present different maps layers of map
sheet 105O03 which show the deposits in the area, the geological
events ,rock units and also a brief sample analysing for
Ag(Silver), Pb (Lead) and Zn(Zinc) elements to prove the presence
of SEDEX (Sedimentary Exhalative Deposits) .

6. The Google Erath map shows the young belt of Cordillera province
which formed billion years ago .Map sheet 105O03 location is :
Lat.: 63.1347 Long.: -131.2661 (Earth Google)
Basin : Selwyn Basin : undeveloped districts and contains massive sulphides

7. The mountain belt series is divided into five belts :
• Insular belt : Volcanic and sedimentary rock type
(C . Hart)
• Intermontane belt : Sedimentary rock type.
(C.Hart)
• Omineca belt : Metamorphosed sedimentary rock
and granite. ( C. Hart)
• Foreland belt :Entirely sedimentary. (C. Hart)
• Coast belt : Granitic rock type. (C. Hart)

8. The area of Map sheet 105O03 is : 689,319,057 m²

9.  Town Map : The closest town to the map sheet 105O03 is Faro
Town .The Faro town has the largest lead and zinc mine in the
world and producer of silver . It’s area is 203’000 squared
meter.

10.  Access : The nearest road to the area is Canol Road .Macmillan
Pass airport is too close to the area from the east and Dall
Mountain from the north west.

12. The area has two types of Faults :
1) Normal/ reverse faults in the lower part.
2) Thrust/ upright faults in the upper part.
Tectonic activity result in faults is very
important for SEDEX deposits formation.

17.  The drainage pattern in the area is dendritic (common
in river ,streams and lakes)Majority of the samples were
collected from the river and the distributary.
 In the area , there are deposits of Silver ,Lead and Zinc .
 The Selwyn basin main types of deposits are is the
SEDEX deposits.
 The tonnage of deposits in Selwyn basin over 9’283’700
tones are as follows:
• Ag 69.4 g/t
• Pb 7.5%
• Zn 6.2%
• Cu 1.81% over 8’510’000 tones
(http://www.geology.gov.yk.ca/pdf/SelwynBasin.pdf)

18. Elements Tonnage
 By analyzing the data for the concentrations of
metals in map sheet 105O03 ,Silver , Lead ,Zinc
and Copper, have the highest concentration
and no concentration for Gold was detected .
 The deposit type could be VMS or SEDEX.
The tonnage value of Sliver is 69.4 g/t which is
higher than in case if the sediment is VMS
( max 30g/t).

19.  Also for Lead , the tonnage is 7.5% which higher than
the tonnage in VMS deposits which maximum 2 %.
 The Zinc tonnage is 6.2% which is close to the
maximum values in both VMS and SEDEX.
 The absence of the Gold concentration , can lead to a
result of type of deposit which is SEDEX.

20. Pathfinder Indicator :
• The area is rich with Shale and Barite and
sedimentary rocks .
• Zn-Pb are shale hosted in an area with faults .
• The Paleozoic deep water environment contains
SEDEX deposits.(Chverier and Turner,2013-2014)
• The SEDEX formation model is Vent distal
• The fluid move along permeable sedimentary rock or
along the fault .

21. Anomalous Values :
Values that occurred above 20th and 90th percentile
Highest Pb concentration 65 p.p.m. at elevation 1360m
Highest Zn concentration 6050p.p.m.at 1160m
Highest Ag concentration 3.8 p.p.m.1240
