SPANISH MOUNTAIN GOLD'S THUNDER RIDGE ARIS REPORT 31360

HAPPY CREEK'S (2010) ASSESSMENT REPORT ON GOLDEN LEDGE

(THUNDER RIDGE NORTH)


The property has had little or no work done to it until 2010 when Happy Creek Minerals soil sampled much of the property for gold and silver and then drilled six holes with limited success.

Spanish Mountain Gold (SPA) owns the adjoining property to the south known as their Thunder Ridge Property and has very encouraging drill results (SC023) less then 250m south of the claim line.  SPA's November 2010 released report documents an airborne VLF-EM Geophysical survey which covers 75% of BC Mining Properties 596446 mineral claim.

After examination of the reports along with other associated data, discreet but specific magnetic anomalies (structures) can be interpreted and may be extremely useful in determining where and how this gold deposit may lie.

Using an MI-HMG model (Measured Inline-Horizontal Magnetic Gradient) several areas of subtle intermediate ranged (not mag high or mag low) magnetic structures are seen within the geophysical maps. After careful plotting and correlating of all significant gold and silver (soil) anomalies on 596446, a pattern appears in that the peripheral edges of these predominately north by northwest striking structures which appear to be coincident to the anomalous gold in soils.

I believe after reviewing this document you will see correlations between the gold in soils and the geophysical structures and drill results in relationship to these structures

 

The Measured Inline Horizontal Magnetic Gradient (MI-HMG) maps above are correlated to drill locations and gold found in soil samples.  A clear north by northwest trend of mineralization is apparent in this model. A less defined trend of magnetics (red) runs north along the east (west of Deception Creek) in the area of DH 23 and 25 heading north.

 

I think it is IMPORTANT to note a couple of things.  One is that wherever Spanish Mountain drilled into or towards one of these structures, they almost always struck gold. With exception of only a couple instances, most of the holes drilled are consistent according to the maps and drill locations. The second is that SPA drilled all of their holes in a westerly direction.  Happy Creek pointed two holes to the east and two to the west at the southern end of the property closest to the Thunder Ridge claim 537095. The two holes they drilled at the north end of the property were drilled in a westerly direction but because the survey did not cover this area the focus in this report is the southern 75% of the claim that is covered.

Another interesting observation is when SPA drilled away from or in an opposing direction from the magnetic structures identified in the MI-HMG model, the assays and intervals reported were weaker than the closest previously drilled holes that were drilled within or penetrated into an anomaly.

Drill-holes SC017 and 10SC027 depicted in the diagram below coincide with this theory.  What is interesting about SC017 are the high-grade intercepts at approximately 130 - 140m.  These intercepts are the benchmark for the Thunder Ridge property so far.  10SC027 was drilled approximately 50m east of SC017 and returned a couple of decent intercepts between 23m - 43m and then another 20m intercept from 221m - 241m but returned nothing in the high-grade gold area on SC017 is at between 130m - 138m (7.5m @ 8.84 gpt). My interpretation is that although the general trend for mineralization is plunging to the NE, the trend to finding additional high grade gold is also to the NW by following the parameters of the discrete geophysical structures indentified in the MI-HMG model maps. Coincidentally the NW area has never been drilled.  Spanish Mountain may have been led in other directions for various reasons, but now after the results of 10SC027 coming in a little week and completely missing the high-grade I think the direction is obvious. The geophysical structure (outlined and shaded predominately green) continues NNW approximately 3km from SC017 and has numerous anomalous gold in soils plotted for the entire length of the structure. At the north end of the structure there are three extremely convincing soil anomalies ranging from 113ppb - 950ppb.

A second example, although somewhat different, but still supporting the same theory, pertains to SC020 that when drilled in 2009 did not intercept anything meaningful as it was drilled outside of any geophysical magnetic structure. In 2010 however, 10SC026 was spotted east of SC020 and appears to have drilled across the top end of a small anomaly. The result on this hole was 6.5m and 3.5m intercepts of low grade gold. I highly suspect if a third hole were to be spotted south and drilled toward the center of the anomaly shown on the map below, the grades and intervals would increase measurably.

Holes 17 & 27 and 20 & 26

A third example is SC023 and 10SC025.  According to the maps SC023 was drilled within the boundaries of what is measurably closer to being a magnetic high but is still in the lower end of the high to low scale. The entire length of the hole was drilled within this spectrum. 

In 2010, 10SC025 was spotted a distance south but most importantly west of the previous hole. This hole returned lower grades than SC023 as the bit progressed away from the magnetic structure.

I appreciate that in order to prove this theory two holes would have to be drilled from the same locations in opposing directions. There are however, too many coincidences on too many holes for it not to be very strongly considered.

Holes 23 & 25

Drill locations correlated to the VLF-QD Model

This VLF-QD model above (page 22 from 31360) appears to be the favored for geophysical interpretation.  There are however, no meaningful correlations to gold values in holes 17, 21 or 22 if interpreting from the highs and lows depicted in this model.  Using the MI-HMG model seems to be more consistent with any drill results to date on the Thunder Ridge claim with the exception of SC012.

If you apply the same logic to the four holes drilled by Happy Creek on the southern portion of 596446 the evidence becomes even more convincing. All four returned no meaningful results and were drilled into areas absent from any geophysical structures as depicted in the MI-HMG model.

I think it is also important to note that at the higher ranges of the magnetics (shaded in red using the MI-HMG model) the gold appears to be of a lower grade and generally deeper in the ground.  In the lower ranges (shaded in green) the gold is generally a higher grade and begins to show at a much shallower depth.  What is most encouraging is that both ranges are returning good gold.

Examples are SC023 and SC017 (seen above).

If the QD model is in fact the chosen model to make interpretations, then there may be a 2 km x 1 km band of gold and silver lying just north of the property line based on the results of SC023 and 10SC025 which were drilled into what appears to be a magnetic high.  As mentioned earlier, this model does not give an interpretive explanation for the excellent results in the area of drill hole SC017. 

FYI: Regardless of which model used, I believe a band of gold does lie north of the claim and more specifically at the top end of the structure where a single soil sample returned as assay of 1200 ppb gold.  This sample is hugely anomalous and must not be overlooked.

In ARIS 31360 there is some discussion about how on one hole they drilled in to a high and hit gold then on the next they drilled into a low and hit gold.

ARIS REPORT 31360

This of off of SPA's website with regards to the latest conclusions after the latest round of drilling on Thunder Ridge

Oct 21, 2010
 

Highlights of Drilling Results Include:

New extension to gold system suggests exploration potential in areas lacking geochemical signatures

I thought this was an interesting highlight and goes to support many of my comments pertaining to this property


What went wrong in 2010?

Upon reviewing the data, it is evident that recent drilling on 596446 has missed the mark.

With proven gold at your doorstep I believe a narrowly-spaced fence should be drilled across the property to give you an indicative path of the trend of mineralization regardless of any geophysical, geological or geochemical interpretations. Once you have done that, you can then determine if the science makes any sense.

Only two of the six drill holes put down managed to come within a 100m proximity to any of the AU soil anomalies (ranging from 18.7 ppb - 1200 ppb).  As well, none of the holes drilled were near the peripherals of any geophysical structures.

Here is a quote from Spanish Mountain's ARIS Report 29139: Soil samples were collected by digging with a mattock to a depth of 30 to 50 cm. Soil samples were shipped directly to Acme Analytical Labs in Vancouver.

Here is a quote from Happy Creek's 2010 AR Report: The B or C horizon soil samples were collected from depths of approximately 25 to 35 centimetres depth, at at 50m spacing...  An approximate sample depth was 15 - 20cm. The samples were placed in labeled Kraft paper bags and hung and dried for a week to 10 days.  Soil samples were packed into rice bags and shipped...to either AGAT or Acme Analytical Laboratories in Vancouver.

Think about it... Two completely different procedures and protocols with different results. It all makes sense when you consider Spanish Mountain who returned a higher frequency of anomalous soils but did not see highs any where near (1200 ppb). Their samples were being dug to almost twice the depth of Happy Creek's.

The highest sample taken on Spanish Mountains 593095 was 532 ppb in 2006. This sample was taken at 5761300N. A second highly anomalous sample of 320.6 ppb was taken 50m due north at 5661350 and then a third sample 50m due north of that at 5761400 returning 69.2 ppb Au.  That's 150m of highly anomalous gold running vertically approximately 500m south of the 596446 claim line.  Unfortunately that is where the 2006 sampling grid cam to an end.

Another interesting point is with regards to what the expectation was with grading of the anomaly. 

Note the Legend at the bottom of Spanish Mountain's soils grid map (2006 report - ARIS 29139):

Now note Happy Creek's Legend at the bottom of the Soils grid map (2010 AR Report)

It seems that what would be considered highly anomalous by Spanish Mountain (anything over 51.5 ppb) would hardly would warrant a look by Happy Creek as anything under 150 ppb was ranked at the bottom of their scale.

Considering that Happy's samples were coming from a depth of closer to half that of SPA, it is not surprising at all that they came back with less than half the frequency of anomalous gold. Overall 537095 returned approximately 28 samples ranging from 100 to 532 ppb. 596446 returned only 8 samples in the same range from 113 to 1200 ppb.  If all was equal and Happy's samples were dug to the same depths a SPA's I think a case could easily be made that the probability for even higher-grade gold than what has been seen on the Thunder Ridge property exists on 596446..

FYI: I have read many reports and it has always been my understanding that in the Caribou Region where overburden is generally very deep that anything below 5 ppb AU would be considered background and anything above 20 ppb would be considered anomalous.  Over 50 would be highly anomalous and anything over 100 ppb is considered hugely anomalous.

One last point pertaining to soil sampling.  I have referred only to SPA's 2006 report 29139 which gold from 499 soil samples ranging to 532 ppb AU.  In the most recent report 31360 conducted in 2009 but released November 04, 2010, SPA did a continuation sampling from the 2006 "Detail" grid in 31360 extending the already sampled area toward the property line to the north and to the east and west so they in attempt to effectively extend their drilling coverage using soils as it appeared to still be the best tool available and they clearly had some decent results so far using this science. What is curious to me about the results is they (SPA) pretty much got nothing back out a couple hundred additional samples (within the 593095 claim area). When you read the report, it states: "Samples were collected digging a hole using a tree planter to approximately 30cm" My bet is a different person dug these samples, and did not dig as deep as the 2006 program which quotes digging 30 - 50 cm deep. Amazingly, the results look much like HPY's results on 596446.  The highest result was 266 ppb with the second highest being 100 ppb with most being within the expected ranges. What I find amusing in all of this is that in the areas of drill-holes SC021, SC23 and immediately north of SC017, they got NOTHING in soils. These are some of SPA's best holes! Then to top things off I see the following statement as one of the highlights on SPA's website after their latest round of drilling:

"New extension to gold system suggests exploration potential in areas lacking geochemical signature".

What does that tell you?  It tells me that although soils are a useful tool, they are not the be all and end all. It also tells me that different soil sample programs will produce different results. 

In this case; we have three different programs 2006, 2009 & 2010 conducted most likely at three different times of the year, dug to three different depths (according to the reports), assayed by three different labs (ACME, Echo-Tech & AGAT) and then analyzed by three different geologists all of which you know darn well all have different philosophies interpretations and expectations. 

I think I have made my point with regards to the consistency in the science of soil sampling.

Part of the lack of success in HPY's 2010 work program may also be related to the frequencies and levels of anomalous silver and too high of an expectation for the levels of gold  in the soils.  I know for a fact that the belief was that the silver would eventually lead them to the gold and I am pretty sure they were  not aware of the geophysical information coming off confidential (2010-11-04) from within ARIS Report 31360. The word "geophysical" is not mentioned their report. 

This information is clearly a gift even though it is a tough one to interpret.

What also may not have been taken into account on HPY's part is that silver is quite mobile. Gold on the other hand gold does not move around much. That being the said; the location where you find gold in soil is most likely close to its source.  When you find silver in soil; you need to ask the question; "how it got there?"

If drill results or lack of are proof in the pudding and being that no gold or geophysical anomalies were drilled, the result is not surprising.

I believe the chances of the gold mineralization Thunder Ridge Property (less than 250m to the south) effectively ending at the claim line of 596446, is very slim. I also believe the chances of coming up short on a drill program after not giving gold in soils (ranging to a 1200 ppb) the merit they deserve, not utilizing valuable data from a neighboring geophysical report and drilling  in areas absent from any anomalies other than silver increases the probability of failure... exponentially.

Lay of the land view (support the migrating silver theory)


Recommendation

My recommendation would be a 16-hole drill program covering many of the anomalous areas I have identified.  I would fly the top portion of the claim and piece together the missing geophysical data in this area if practical.  The three soil samples in this area range from 113 - 950 ppb AU and may be convincing enough to justify drilling ahead without it. I would at least resample and map the immediate area surrounding these anomalies to better insure drilling success.

 


Please see the individual links below. They were the data that was available to me prior to Happy Creek's report which came to me and was filed with MTO on February 11th, 2011.  If in doubt; refer to the actual report because there are some discrepancies.

On a side note and with all due respect to Happy Creek Minerals; I think they are a very good company. I just believe they missed big on this one and do not want this property which I view to have the potential to become the other half of the Thunder Ridge Gold Deposit painted with the wrong brush in spite of an unsuccessful work program.

Many great properties have taken as many attempts before they proved out to be winners.  Eskay Creek is a perfect example.

JANUARY 12th, 2010 NEWS RELEASE

SEPTEMBER  1st, 2009 NEWS RELEASE

JANUARY 14th, 2009 NEWS RELEASE

 
 
 

The last documented soil sample taken was approximately 545 metres south of the claim boundary and approximately 100m SW of drillhole SC007 where Skygold sampled what they called the "detailed soil grid".  The area was described as being 700m x 800m. In the most recent update Skygold (Sept 01) indicated:

"All of the drilling has been completed within an 850 metre by 350 wide metre corridor which is contained within a 1500 metre by 800 metre wide gold soil and rock sample anomaly."

The most southerly hole drilled to date according to Skygold's  reporting is SC006 apparently which returned  no measurable result.  If the anomalous area has since grown from 800 metres 1500 metres and SC006 returned nothing; the continued focus of exploration has to be to the north. Based on the newly indicated size of the anomaly (1500m),  Skygold may  have already geochemically sampled their way on to 596446 by as much as 500m or more.

The maps above depict the claims as well as the general  (northerly) drilled area.  I have plotted the approximate locations of *DH SC017 & *DH SC007 which  are located approximately 325m and 440m respectively to the south of the 596446 southern claim line. 

Note the structural corridor which is quoted as being "open in all directions".

September 1, 2009 Drill Results

*Hole SC-017 located approximately 325m south of the claim line intersected  8.84 g/t gold over 7.5 metres including 39.50 g/t gold over 1.5 metres and a second zone of  2.14 g/t gold over 9.0 metres including 9.45 g/t gold over 1.5 metres and 1.13 g/t over 19.5 metres.

Hole SC-018 intersected 2.88 g/t gold over 24.0 metres including 9.68 g/t gold over 6.0 metres and including 18.05 g./t gold over 3.0 metres

Hole SC-015 intersected 3.23 g/t over 6.0 metres including 11.40 g/t gold over 1.5 metres  

Gold mineralization is noted in several styles including quartz vein hosted, structure controlled and disseminated zones in black shale sequences. Early interpretation indicates that there may be several sub-parallel or folded zones of gold mineralization.

“These current results demonstrate the good potential for a high-grade gold deposit at Thunder Ridge.  This new discovery has returned significant gold values in quartz veins within an 850 metre by 350 metre area and remains open in all directions. 

Nine of the ten holes completed intersected gold mineralization which is a very high success rate and even more compelling considering the zone does not outcrop.  The wide spread nature of the gold mineralization, high grade values and multiple zones of quartz veining highlight the potential of the area. Thunder Ridge has the potential to host a large scale gold deposit with high grade structurally controlled zones.  Skygold has already discovered a +2.5 million ounce deposit in this belt of rocks and we are very excited to see Thunder Ridge developing into a significant gold deposit.”

January 14, 2009 Drill Result

*Hole SC-007  located approximately 440m south of the claim line intersected  1.23 g/t gold over 11.5 metres including 4.83 g/t gold over 1.5 metres and 1.32 g/t gold over 6.5 metres in separate horizons.
