Napkin Math for Purple Area in Fig 2Here is an attempt to estimate the potential ounces in the purple area (Lower Tabasco Zone) in Fig 2 of the latest NR, link below:

Case 1: Assumptions:
- 250m width x 500m depth and an average of 10m thick (into the page): 250 x 500x 10 x 2.8 = 3.5M tonnes.
- Grade: minimum 5gpt
- Ounces: 3.5 M tonnes x 5gpt/31 = 0.5Moz
Case 2: Using the gpt-m as shown in Figure 2 as a guide
- 250m x 500m= 0.125M m2
- Straight average (i.e. not weighted) of about 1 holes with values ranging from 51gpt-m to 1091 gpt-m (hole 86, note deepest hole #99 has 76gpt-m: 2015 gpt-m/10 = 201gpt-m
- Ounces: 0.125M m2 x 201gpt-m/31 = 0.81M ounces.
The above estimates are for a 200m section along the Tabasco zone strike (running in the NW-SE direction, as shown in Figure 1. Note also that there are many more zones beside Tabasco in Figure 1. As an order of estimate assessment I would say one can apply a factor of 10x on the above results considering the strike length of 1km (only 250m was assummed), and the coverage area of about 1km (perpendicular to the strike). Hence the RE would be expected to be of the order 5M-8Moz Au.
Any comments on the above approach?
