Copy the values of a collection to a 2D array in VBA - arrays

Question

I seem to be banging my ahead against the proverbial brick wall. I have a loop which runs and populates a collection. There are approximately 20000 rows and 11 columns. I need to be able to get the contents of the collection into a variant array so that I can do a bulk copy to a worksheet. The reason I was using a collection is for the inherent de-duplication of entries.
Please could someone offer a suggestion as to how to achieve this. I assume I am missing something straightforward but if I dont use a collection I need to dedupliate 200k+ rows.
Thanks in advance for all your help
EDIT
Here is the actual code. As I mentioned above, the problem is not getting the data into the collection (MyCollection), its getting it out again!
EDIT
The flow of data starts in a worksheet which is then copied into an array called ArrayOrg. The array is looped through and when certain conditions are satisfied, a record is added to the ArrayOrg1 array. Please see the code below.
For intI = 1 To UBound(ArrayOrg())
If ArrayOrg(intI, 7) = "cMat" And ArrayOrg(intI, 5) = "Plant" Then
ArrayOrg1_cMat(Org1Count_cMat, 0) = ArrayOrg(intI, 1) 'User ID
ArrayOrg1_cMat(Org1Count_cMat, 1) = ArrayOrg(intI, 2) 'BR ID
ArrayOrg1_cMat(Org1Count_cMat, 2) = ArrayOrg(intI, 3) 'Scenario
ArrayOrg1_cMat(Org1Count_cMat, 3) = ArrayOrg(intI, 4) 'Role
ArrayOrg1_cMat(Org1Count_cMat, 4) = ArrayOrg(intI, 5) 'Controlling Field
ArrayOrg1_cMat(Org1Count_cMat, 5) = ArrayOrg(intI, 6) 'Controlling Field Value
ArrayOrg1_cMat(Org1Count_cMat, 6) = ArrayOrg(intI, 7) 'Webapp
Org1Count_cMat = Org1Count_cMat + 1
Next intI
Dim MyCollection As Collection
Dim ArrayTemp() As Variant
Set MyCollection = New Collection
For intI = 0 To UBound(ArrayOrg1_cMat())
For intJ = 0 To UBound(ArrayOrg2_cMat())
If ArrayOrg2_cMat(intJ, 0) = ArrayOrg1_cMat(intI, 0) Then
If ArrayOrg2_cMat(intJ, 1) = ArrayOrg1_cMat(intI, 1 Then If ArrayOrg2_cMat(intJ, 2) = ArrayOrg1_cMat(intI, 2) Then If ArrayOrg2_cMat(intJ, 3) = ArrayOrg1_cMat(intI, 3) Then
ArrayTemp(0, 0) = "" 'Name
ArrayTemp(0, 1) = ArrayOrg1_cMat(intI, 0) 'AD ID
ArrayTemp(0, 2) = "" 'Email
ArrayTemp(0, 3) = "" 'Requester
ArrayTemp(0, 4) = ArrayOrg1_cMat(intI, 6) 'Webapp
ArrayTemp(0, 5) = ArrayOrg1_cMat(intI, 2) 'Scenario
ArrayTemp(0, 6) = ArrayOrg1_cMat(intI, 3) 'Role
ArrayTemp(0, 7) = "PL" 'Business Unit
ArrayTemp(0, 8) = "NONE"
ArrayTemp(0, 9) = "NONE"
ArrayTemp(0, 10) = "NONE"
ArrayTemp(0, 11) = ArrayTemp(0, 0) & ArrayTemp(0, 1) & ArrayTemp (0, 2) & ArrayTemp(0, 3) & ArrayTemp(0, 4) _
& ArrayTemp(0, 5) & ArrayTemp(0, 6) & ArrayTemp (0, 7) & ArrayTemp(0, 8) & ArrayTemp(0, 9) _
& ArrayTemp(0, 10) '### This is the key for the collection
On Error Resume Next
MyCollection.Add ArrayTemp, ArrayTemp(0, 11)
On Error GoTo 0
End If
End If
End If
End If
Next intJ
Next intI
'#### THIS IS WHERE THE PROBLEM IS
For intI = 0 To MyCollection.Count
ArrayOutput(intI, 0) = MyCollection.Item(intI)
Next intI
Thanks
