Subject: RE: New Horizon Mine
Hi Edward,
I could suggest sampling for the following items, pH, EC, texture estimate (using the ribbon or similar method),
soil color, effervescence (presence or absence of carbonates), estimate of % RF's (rock fragments) - sizes and
amount by volume. I would split any layers within this subsoil that are contrasting (came form different
replacements) in any of these characteristics. If your sample indicates significant effervescence using HCL (1 N),
or visual observations of significant calcium carbonate (masses, threads, coats on frags) you may opt to collect a
sample and run a calcimeter to determine the CaC03 equivalent. This is a simple test that usually takes about 3
to 5 minutes to run and requires just a couple of test items and chemicals (10% HCL). It is usually run inside.
This is a more comprehensive list. If you just wanted to describe essentials only, they would be in my estimation
texture, pH, EC if pH is above 8.4, and amount and sizes of RF's.
Using this information, you can then compare to the requirements for Prime Farmland and to the soil
descriptions of the original soils found on the site (In this case the Barx or Devinny soils). You also have the data
collected by Intermountain Resources to help you as a baseline for comparison. I would suggest keeping in mind
some of the conversations we had during our meeting on the 15th, when comparing the replaced subsoil with the
PF requirements. For most agricultural uses, the topsoil is much more significant than the subsoil (though in our
conversations you can't assume that anything replaced will suffice for subsoil requirements). Hope this helps. If
you have difficulties developing a list of parameters for subsoil replacement characteristics using this information,
please feel free to contact me and we can discuss this further.
Dave

Subject: New Horizon Mine
Dear David:
We are proposing to sample the top two feet of subsoil that has been placed over the 98E (Prime Farmland)
mined portion of the New Horizon Mine. It will have approximately two feet of reclaimed topsoil placed over it.
Please provide an analyte list that you think is appropriate to determine if the placed suboil is appropriate for the
lower horizons of soil. THank you for your time.
Sincerely,
Edward M. Baltzer
