Visualizing the Drill Programs at OrenadaHey All,
I wanted to see how the recent drill results compared with the 2007-2008 drill results used in the first resource estimate at Orenada. I knew the recent results were better, but by how much? Well, I created several charts to explore this question at a high level. Two things really stood out for me: the amount of drilling between the programs and the improved grades in the current program.
The first chart compares core samples by the length of intercepts and the grade of each intercept. The length of the bars is the total length of intercepts (if you had place each intercept next to each other horizontally). The color represents the avg. au grades between 0 and 4 g/t in increments of 0.5.
The second chart is a histogram that counts the number core samples that have grades multiplied by intercept length above 25. Any sample below this 25 number is disregarded for this analysis.
The third chart is a scatter plot that compares the order of when a sample was drilled and the resulting number from multiplying intercept length and grade.
For example, an intercept length of 100 with a grade of 2 g/t would result in a final number of 200. The top intercepts from this calculation have annotations with more detail. The color indicates which drill program the sample belongs to.
After visually analyzing this data, I must admit it's difficult for me to temper my expectations about the upcoming resource estimate. Although this is only a high-level analysis, it's clear to me that the recent results are substantially better than the first fifty holes drilled in 2007 and 2008. This also may explain the increased interest in Alexandria.
Let me you know what you think,
