West-Central Yukon, Canada
POTENTIAL LARGE-SCALE PORPHYRY
ALOTTA IS A WORLD-CLASS OPPORTUNITY
The Yukon has been undergoing extensive and highly successful mineral exploration discoveries.
The Alotta Property is situated approximately 40 kilometres south-east of the Casino Au/Cu porphyry deposit.
Recent success in the region is evidenced by the Casino Project, amongst one of the largest undeveloped Gold/Copper deposits in the World.
Notice the proposed road from the Revenue Mine to Casino in purple. Other routes are being proposed that would come close to the property.
OVER 4 BY 1 KMS OF IN-SITU GOLD SOIL GEOCHEMISTRY
Alotta Property consists of 74 mineral claims that cover over 1550 Ha. along the Dawson Range, Yukon.
The property is centered on the top of a hill, topography is not rugged and has not undergone glaciation.
No glaciation is important as this indicates no dispersion (expansion) of the in-soil geochemical anomalies.
The adjoining Google vertical view map provides a view of the topography with anomalous gold in-soil geochemistry overlaid.
SIMILAR GEOLOGICAL SETTING TO CASINO PORPHYRY
Located in similar geological setting as the Casino Deposit consisting of several Mesozoic intrusive phases. This can be concluded with the following interpretations:
- Dawson range
- Same Geological Era
- Composition and texture
The intrusive phases consist mainly of intermediate composition with porphyritic textures.
Majority of phases are moderately to highly magnetic, however at Alotta the magnetics is low, possible due to hydrothermal fluids depleting the primary magnetite, another classic feature of porphyry style mineralization.
OVER 4 BY 1 KMS OF IN-SITU GOLD SOIL GEOCHEMISTRY
Area of interest where magnetite depletion occurs in the intrusive complex typically consisting of moderate to high magnetics.
Magnetic depletion is probably the result of sulphur enriched, hydrothermal fluids reacting with magnetite to develop sulphide mineralization.
Coincident copper/gold in-soil anomalies to areas of magnetic depletion further supports the porphyry model.
RADIOIMETRIC ANOMALY COINCIDENT WITH COPPER-GOLD IN SOIL ANOMOALIES SUPPORT PORPHERY POTENTIAL
Total potassium counts from radiometric, airborne survey indicate large potassic highs within area of magnetic depletion and coincident copper/gold in-soil geochemical anomalies.
High potassic radiometric anomalies typically occur in alkalic porphyry systems that can generate copper/gold deposits.
DISTAL BASE METAL ZONATION OF POTENTIAL ALKALIC PORPHERY
Typical of Base Metal Zonation of Alkalic Porphyry systems base metals such as zinc are distal to the central copper-gold area of mineralization.
AREA OF HIGH CHARGEABILITY ASSOCIATED WITH GOLD IN SOIL GEOCHEMISTRY
Induced Polarization Survey completed in August.
The plan image shows only the >30mV chargeability results from the 2D IP-Res model overlain by gold-in-soil and magnetic susceptibility (RTP). The dashed polyline highlights the area of greatest interest for further testing given the occurrence of favorable geochemical and geophysical anomalies. Diamond drill testing within this zone is recommended for further exploration to better understand the cause of the chargeability, elevated soil geochemistry, and relative magnetic lows.
Note: Area of interest over 2.0 kilometers inferred strike length
SIZE POTENTIAL OF ALOTTA ANOMALOUS GOLD-COPPER IN SOIL ANOMALY COMPARED TO CASINO DEPOSIT
The Casino Deposit outlined in the blue dashed lines covers only a portion of the unglaciated, copper-gold in soil geochemistry.
The Casino deposit has 2.17 billion tonnes of measured and indicated resources containing 7.4b lbs. copper and 12.7 m oz. gold.
Casino PEA June 22, 2021 for Western Copper
November 2023 Drill Program
Shown to the right is a plan view of chargeability results from the 2D IP-Res model overlain by gold-in-soil and magnetic susceptibility (RTP). The dashed polyline highlights the area of greatest interest for testing given the occurrence of favorable geochemical and geophysical anomalies.
The figure also illustrates two proposed NQ diamond drill holes which are now completed. Proposed PDDH_001/002 are now completed as ALT-23-001/002respectively. Program proposed to continue in spring.
Assay results are pending.
OBSERVATIONS FROM DIAMOND DRILLING CORE
Both holes exhibited multiple intrusive phases including intrusive breccias displaying strong biotite alteration, carbonate veining and pyrrhotite, pyrite, chalcopyrite and molybdenite mineralization as interstitial clots and stringers.
The photo shown is from ALT-23-001, at approximately 17-metre depth illustrates the shreddy brown biotite alteration coincident with interstitial and veinlet style mineralization.
