Ann: Visual Sulphides in Tiger Cu-Au-Zn-Ag Drilling, page-13

6 out of 8 holes intersected sulphides, so thats a great start.

*The information provided in the table gives a detailed breakdown of the types of sulphides and their distribution in the drill holes at the Tiger Cu-Au-Zn-Ag prospect. Here's what it tells us:

1. Sulphide Types and Mineralization Style:

   • The sulphides identified include pyrite (Py), chalcopyrite (Cpy), sphalerite (Sph), galena (Gln), and arsenopyrite (Apy).
   • These sulphides are found in different mineralization styles, including disseminated (widely spread within the rock), laminated (layered), and stringer (thin veins or strings of mineral).
   • Disseminated and laminated mineralization styles are common in Volcanogenic Massive Sulphide (VMS) deposits, suggesting the potential for significant base metal deposits.

2. Concentration of Sulphides:

   • The sulphide concentrations vary across different intervals, ranging from 1% to as much as 15%.
   • Higher percentages (e.g., 5-15%) of sulphides like chalcopyrite, sphalerite, and galena in specific intervals (e.g., TIGERC003 from 31-43m) are particularly promising as these intervals might represent zones of higher-grade mineralization.

3. Depth and Thickness:

   • The intervals with significant sulphide mineralization occur at various depths, from near-surface (e.g., 9m in TIGERC003) to deeper levels (e.g., 139m in TIGERC002).
   • The thickness of these intervals varies, with some reaching up to 15 meters (e.g., TIGERC005 from 47-62m), indicating potentially substantial zones of mineralization.

4. Presence of Arsenopyrite (Apy):

   • The presence of arsenopyrite (Apy) in some intervals (e.g., TIGERC003 and TIGERC005) can be significant because arsenopyrite often associates with gold in many types of deposits. This might suggest the potential for gold mineralization alongside base metals.

5. Potential Economic Implications:

   • The combination of chalcopyrite, sphalerite, and galena in multiple intervals and styles suggests that the Tiger prospect may contain a polymetallic deposit with copper, zinc, lead, and possibly gold and silver. These types of deposits are economically attractive due to the presence of multiple valuable metals.

*The data provided from the drilling program at the Tiger Cu-Au-Zn-Ag prospect appears promising, but there are a few potential concerns or considerations that should be kept in mind:

1. Visual Estimates: The sulphide percentages provided are based on visual estimates, which can be subjective and less accurate than quantitative measurements. While experienced geologists can provide reasonably accurate visual estimates, these should be confirmed with laboratory assays to ensure the true grade and concentration of the minerals.

2. Sulphide Concentration Variability: The sulphide concentrations reported range from 1% to 15%, with many intervals on the lower end (1-5%). While this is typical in many deposits, the economic viability of mining these intervals depends on the overall grade and tonnage. Low sulphide concentrations might not be economically viable unless accompanied by higher grades in other intervals or in larger volumes. Further assay data is required.

3. Depth and Thickness: The mineralized intervals vary in depth and thickness. Some intervals are quite thin (e.g., 2-3 meters), which could pose challenges in defining a consistent and economically mineable resource. Consistency in the thickness and grade of mineralization is important for the development of a resource.

4. Presence of Arsenopyrite (Apy): The presence of arsenopyrite is a double-edged sword. While it can be associated with gold, it also contains arsenic, which can be problematic from both an environmental and processing standpoint. High arsenic levels in ores can lead to increased processing costs and environmental liabilities.

5. Confirmation Needed: The data relies heavily on early-stage exploration results. Follow-up drilling, assays, and geophysical surveys will be necessary to confirm the presence and continuity of the mineralization. Until these results are in, the potential resource remains speculative.
