Jade Leader Reveals Color Change Phenomenon Jades from its DJ Project,
Washington State, USA
Calgary, Alberta – Jade Leader Corp. (TSX.V: JADE) (“Jade Leader”, or “the Company”) is pleased
to reveal a new type of nephrite Jade to the gem and collector world markets. This Jade has a unique
color change phenomenon whereby depending on the specimen, the color can shift from white to
blues to dark green as the viewer’s eye moves in relation to the stones. Gemologists refer to
gemstones showing unusual optical effects such as color change, chatoyancy or asterism as
“phenomenon stones”, which can be highly prized by collectors and specialty jewellers.
“To our knowledge Jade showing this color change phenomenon has never been documented before,
so we had to create the most appropriate cutting and shaping techniques to properly exhibit the optical
phenomenon from scratch”, stated Mr. Jean-Pierre Jutras, P.Geol., the President of Jade Leader. “We
combined scanning electron microscope mapping, thin section and hand sample microscopy with trial
and error lapidary work to understand how the stone’s crystallographic fabric interacted with light to
create this effect”, stated Mr. Jean-Pierre Jutras, P.Geol., the President of Jade Leader.
Figures 1 to 7 below show a series of cut stones from Jade Leader’s 100% owned DJ project which
display color and texture variations on this color change phenomenon. While still photographs can
illustrate how colors are seen from static viewing angles under daylight LED studio conditions,
movement is needed to reveal the dramatic shimmering dramatic color transitions. Readers are invited
to watch a special video of the stone’s full visual effects presented in our latest Youtube Channel
video “Change in the Jade World” here .
Figure 1: Composite picture of cabochon cut stone (JLCC5), showing the color change as the stone is rotated
relative to a fixed light source. Stone is 36.5 mm by 35 mm in diameter and weighs 17.6 grams/87.9 carats.
Figure 2: Composite picture of cut stone(JLCC4). Stone is 36.6 mm by 36.1 mm in diameter and weighs 33
grams/165 carats.
Figure 3: Composite picture of cut ring stone (JLCC7). Stone is 11.6 mm by 12.5 mm in diameter and weighs 0.94
grams/4.7 carats. While chatoyant or “cat’s eye” Jades (both nephrite and jadeite) have been documented before
from various locations, chatoyancy refers to a band of light caused by reflection along inclusions or parallel
underlying fibers within the stone. It is not associated with an actual change of perceived color for the body of
the stone itself.
Figure 4: Composite picture of cut ring stone(JLCC8). Stone is a round 8.8 mm and weighs 0.54 grams/2.7 carats
with a high vitreous luster and sharp transition from white to green.
Figure 5: Composite picture of cut stone (JLCC10). Stone is a 17.1 mm by 7.4 mm marquise cut cabochon and
weighs 0.7 grams/3.6 carats. High vitreous luster, high translucency in bands, and sharp color changes from dark
to light greens and light blues.
Figure 6: Composite picture of cut stone (JLCC9). Stone is a 23.5 mm by 7.8 mm drop cut cabochon and weighs
2.13 grams/10.6 carats.

Identification work conducted to date on this material from surface samples relied heavily on
SEM/EDS (Scanning Electron Microscope/Energy Dispersive X-Ray Spectroscopy) as well as thin
section and hand sample microscope work to understand the relationship to perceived color to the
main mineralogical characteristics of the nephrite Jade itself.
SEM/EDS analysis work performed at the University of Arizona determined that the samples are
dominantly composed of long fiber tremolite (the main constituent of Nephrite Jade), with minor
inclusions of both biotite and chromite. In addition, different chemical compositions were noted in
different growth generations of the tremolite, including variable iron contents, which appear to affect
color. The Company believes that the color, and the color change phenomena, are caused by a
combination of varying chemical composition between different growth stages and the “fabric”
created by intergrowths of different growth stages of the fibrous Jade minerals. The most dramatic
effects tend to appear when the stone is viewed at a high angle, so Jade Leader had to develop
specialized cutting techniques to properly highlight the various color change effects in any given
stone.
About the Color Change Occurrence
This Color Change Jade has been found in surface trenches at the Lode 2 Jade occurrence of Jade
Leader’s Washington DJ project. Here, a Jade-bearing structure is intermittently exposed at surface
for some 50 meters and has been followed by drilling to depths of up to approximately 30 meters (NR
19-01, Jan 30 2019). Most of the surficial Jade was heavily weathered, although some larger samples
had fresh cores which provided materials for developing the appropriate cutting protocols.
Way Forward
Now that we understand these new Jades and have cut a suite of fine stones, the Company is
considering its best options for marketing these materials to the Collectors’ market. Meanwhile, field
tests are underway to determine if it is possible to get below the surface Jade weathering horizon on
site with minimal disturbance. This would allow the Company to plan a pilot field program to
determine potential yields through trenching along the known occurrence, as well as provide
additional materials to bring to market.
The Company also continues to expand its audience of international carvers, jewelry manufacturers
and industry professionals by routinely updating product information on social media, including
posters and videos relating to its current Jade products and inventory. Such postings can be found
both on the Company’s Youtube Channel under Jade Leader Corp, and on Instagram

About Jade and Jade Leader Corp.
Recent articles suggest that the international Jade market is now larger than the better-known
worldwide market for rough diamonds, without any participation in the space by publicly listed
Companies prior to the formation of Jade Leader Corp.
Jade Leader Corp, with a Board of Directors having over 120 years of combined experience as mineral
exploration geologists with proven track records of discoveries, is led by JP. Jutras, B.Sc. Hons
Geology, P.Geol who is also an internationally recognized Jade carver with over 30 years of
experience.
Jade leader is leveraging this unique combination of mineral exploration expertise and Jade carving
knowledge to build a portfolio of 6 Jade exploration properties on which Nephrite Jade with various
characteristics has now been identified in stable, mining-friendly jurisdictions in the USA.
On Behalf of the Board of Directors,
