Q1: Do you have a theory of how deep is the Comstock?
A1: Most mining districts have a known bottom due to
specific geochemical components such as Pressure-Temperature can determine the bottom of a lode district.
The bottom of the Comstock Lode District has not been found.
Eventual deep drilling will give clues to what is the bottom of the Comstock mineralization,
Q2: What do you define as Deep Drilling?
A2: Many previous workings in the area of Goldspring control have excavated to depths of 2200 feet.
2,000 feet = Deep Drill
3,000 feet deep is possible for R/C and Core Drilling. Scott has prior experience with several other companies that have drilled much deeper.
4,000 feet deep = near max capability of many drill rigs.
Q3: What does it mean when a Drill Report states the "drill bottomed in ore", "ended in a stope" - Why couldn't the drill go deeper?
A3: Goldspring activity is over prior extensive underground workings. so there are zones where substantial excavation has created a large volume of air - a stope.
When a drill enters a stope from an angle the span of air may be too long so the drill will waggle, like a loose end of a water hose, so much that it can not get a bite into earth on the far side of the cavity.
If the twisting continues it could disturb unstable soil causing an underground slide, deform a section of drill pipe locking the tube in the earth and could even break it. Drill bits and sections are expensive, so instead the drilling stops and the drill tube is retracted to the surface.
Drilling will continue from another angle as they want to know what is on the other side of the excavated volume of prior underground mining, the stope.
Q4: Oxidation of Rock in an Ore Zone, cases of heavy oxidation with many fractures and faults.
A4: If drill crosses through such a zone it can put too much torque on the rod -
creating a potential for a loss of an entire string of drill rods.
Friction with many abrasive minerals can lath cut a drill rod to sever completely.
The community of blocks are further verified and refined by correlating the impact of the next shell of blocks further out upon the innermost shell. Then that is done again for another shell outward impacting the 2nd shell and how it impacts the first shell.
A simplistic 1st shell can be viewed as a cardboard box and a wad of paper inside as the core block. Therefore each block is impacted by 26 surrounding blocks:
Find a cardboard box. With a marker, color each corner. Then color the midpoint of all edges. Then mark the midpoint of each face. Count the spots:
A box has
_8 corners
_6 faces (4-sides with 1-top and 1-bottom) mark the middle of face
12 edges (4-horiz at top, 4-horiz at bottom, 4-verticals) mark middle of each edge
==========
26 spots represent the data of 26 adjacent blocks of subterra
Saying the same in a more mathematical sense:
a. 8 horizontal adjacent blocks:
____the 4 cardinal directions North and South, East and West (NSEW), plus
____the 4 corners in between: NE, SE, SW and NW;
like tic-tack-toe .
plus tilt the tic-tack-toe vertically and rotate
b. 10 vertical adjacent blocks:
____the 2 blocks above and below, plus
____4 (each end of a vertical "X")
____4 (each end of a vertical "X" rotated 90 degrees)
[a 3-D cross like a child's jacks spinner on end]
plus
c. 8 more 3-D diagonals, vertical and horizontal
____4 by a 45 degree rotatation of the 1st vertical "X"
____4 by a 45 degree rotatation of the 2nd vertical "X"
________(the eight corners of a box)
--------------------------
= a total 26 blocks in a basic 1st cubic shell.
A second shell next step outward yields even more blocks as each block size remains the same, so the a larger cube-shell further out occupies greater length, width and depth, hence more blocks.
Cube-Shell Two:
One more row top and bottom plus each side = 5x5 = 25 blocks at front x same at back = 50 front & back
At top: 3W x 5L = 15 x same for bottom = 30 top & bottom
At last two sides: 3W x 3L = 9 x the other side = 18 last two sides
----------------
= 98 blocks in shell two adjacent to shell one.
Core block affected by 2 shells =
_26 blocks by shell one
_98 blocks by shell two
=
124 blocks
Shell Three:
_98 = 7x7x2 = Front & Back
_70 = 7x5x2 = Top & Bottom
_50 = 5x5x2 = remaining 2 sides
=
218 blocks
124 + 218 = 342 blocks in 3 shells around one core block
