Message: NAM comparison to NA Palladium

 

Recent trading in NA Palladium made me wonder how NAM and PDL compare.

 

 

 

PDL HISTORY

 

 

 

  • 1986 – Madelaine Mines acquired 50% LDIM from Sheridan Palladium

  • 1993 – Madelaine becomes PDL & acquires 100% of LDIM

 

  • Dec 1993 - Lac des Isles Mine (LDIM) started open pit production at Roby Mine.

  • ore was crushed & milled on site then toll processed by Inco (25%) and Falconbridge (75%)

  • Palladium was sold to a large auto manufacturer

  • PDL reported a loss of $5.2M in 1999

  • 2000 - Agra Simons Feasibility Study recommends $207M expansion program

  • 2001 – new mill & concentrator started operation

  • 2004 RPA Study recommended U/G mining

  • 2006 - LDIM started U/G production at Roby Mine below the pit via ramp access

  • Oct 2008 - Roby mine placed on care & mtce due to low metal prices

  • Exploration drilling continued during & following the shutdown

  • RPA did several technical Reports during shutdown to determine viability of LDIM

  • During shutdown mill was redesigned to include SAG mill, jaw crusher & new flotation circuit

  • Mar 2010 - LDIM resumed U/G production

  • Nov. 2010 - RPA study reported PDL was now selling its concentrate to Xstrata in Sudbury.

  • 2013 - a shaft to 825M was completed to access the offset zone

  • 2014 – Tetra Teck report - Life of Mine Plan

  • 2014 – concentrator started operating full time ( was 2 weeks /mo.)

  • 2015 – Hatch PEA for Mine Expansion was prepared

  • Apr 2015 – PDL delisted on NY stock exchange

  • May-June 2015 – operations suspended – water issues

  • July 2015 – recapitalization & officer resignations

  • Sept 2015 – worforce reduction & further recapitalization (Brookfield)

  • Q3 2017 - PDL reported Net Income of $11M for Q3

PDL COMPARISON TO NAM

 

 

 

2012 NAM Mineral Resources (Tetra Tech Report)

 

 

 

Measured 91.3M T 0.58g/t PD 1,867,899 OZ PD

 

Indicated 35.9M T 0.36g/t PD 455,881 OZ PD

 

Total 127.2 M T 2,323,781 OZ PD

 

 

 

NOTE: NAM Palladium conversion of grams to ounces = 0.035274g/oz)

 

 

 

 

 

GRADES

 

 

 

  • notice that the PDL underground grades are significantly higher than the surface/open pit grades

  • I suspect the same would be true if NAM were to do some deep drilling

  • the 2006 43-101 GeoSim study reported palladium grades of 1.33g/t PD

  • the 2012 Tetra Tech study reported much lower palladium grades

  • this is because the tetra tech study targeted a large-tonnage low-grade open pit model

  • 2017 drilling in the footwall revealed much higher grades at very shallow depths

  • the inclusion of 2017 drilling in the 2018 RE should greatly increase the palladium ounces

 

 

 

RESERVES & RESOURCES (R&R)

 

 

 

  • PDL total R&R is 71.7M T verses 127.2M T for NAM

  • the PDL RE was produced in 2017 verses 2012 for the NAM outdated RE

  • This equates to 4.5M OZ PD for PDL verses 2.3M OZ PD for NAM

  • this is because the resource estimate for NAM assumes high tonnage open pit mineral extraction at lower grades palladium

  • assuming a 20% increase in 2018 we get...

  • 153M T

  • open pit grade = 0.7g/t PD ( 2017 grades were over 1 g/t PD)

  • 3.8M OZ PD

  • NOTE: This does not include other payable metals, AU, PT, CU,NI,Rh)

 

 

 

 

 

OBSERVATIONS

 

 

 

  • this comparisson underlines the economic value of the River Valley deposit

 

  • PDL has a long history and a lot of money spent on Technical reports

  • This comparison shows the importance of the new Technical Report and Metallurgical study

  • NAM resources are based on 2012 data and grossly out of date

  • NAM will have the cost advantage of an open pit mine

  • NAM will not have the expense of a mill if supported by Vale or Glencore

 

 

 

 

 

 

 

CONCLUSIONS

 

 

 

 

 

  • the RV deposit will utilize less expensive open pit methods of mining

  • RV is 100km from Vale verses 1000km for PDL

  • 2017 drilling demonstrated comparable grades in the footwall at RV

  • only 3 km of the 16km strike length has been included in the resource estimate

  • the NAM resource size and grades are comparable to PDL with much more potential for growth

  • the next step for NAM may be a JV with a bigger company

  • PDL has returned to profitability and could afford to invest in 20% of NAM

  • possible JV partners include Vale, Glencore, PDL, Anglo American
