Firstly you need to decode these clues and work out who the club is.
G = Lucky or Unlucky Animal depending on your opinion
H = Male Deer
I = Sticky Sweets
J = Christmas Bird (another clue to go with that is Scrumpy)
K = Insect With Alkaline Sting
L = Horned Farm Animal
M = Colour of Sky in London
N = Scouse Tomatoes
O = Attaches to cowboy boots

T = Joker, Penguin
U = Bags
V = Swords and Knives have these
W = These make beer
X = Birds used by miners
Y = Nocturnal mammal, eats rabbits and smaller mammals
Z = Bird, Over The Rainbow
Now just some simple calculations, and you can go and find the cache which can be found at
N54 51.ABC W001 29.DEF
A = (H-J) x (G-I) - (W-X)
B = (G+T) / (V-P) - N
C = (O+S) - (Y+Q) + (V-K)
D = (Z+X) - (L+M) - (Q-R)
E = (U+W) / V + (Y-N)
F = ((M+N) + (S-K)) / (U-W)
You can validate your puzzle solution with certitude.
