Adding values to a dynamic array and then printing to specified cell - arrays

Question

I'm searching a range in my sheet for certain values when either of these values is found I want to add the value from column A of that row to an array, only adding values that are not already present in the array. Once the range has been searched, I want to print the arrays to specified cells in the worksheet in 2 different columns.
Here's my code so far:
Dim Ws As Worksheet
Set Ws = Sheets("Sheet1")
Dim Leave() As Variant, Join() As Variant
Dim LastCol As Integer, LastRow As Integer, i As Integer, Z As Integer
Dim J As Long, L As Long
With Sheets("Sheet1")
'Find Last Col
LastCol = Sheets("Sheet1").Cells(3, Columns.Count).End(xlToLeft).Column
'Find last Row
LastRow = Sheets("Sheet1").Cells(Rows.Count, "A").End(xlUp).Row
LastRow = LastRow - 1
'ReDim Leave(1 To (LastRow - 1), LastCol)
'ReDim Join(1 To (LastRow - 1), LastCol)
For i = 5 To LastCol
For Z = 4 To LastRow
If Sheets("Sheet1").Cells(Z, i).Value = "0" Then
Leave(L) = Ws.Cells(Z, 1).Value
ElseIf Sheets("Sheet1").Cells(Z, i).Value = "-2" Then
Join(J) = Ws.Cells(Z, 1).Value
End If
Next Z
Next i
'Print array
End With
Thanks for any pointers/help in advance!

I believe this procedure accomplishes what you are looking for. You will need to modify the range in which you are searching and the destination sheet information, but the meat of the procedure is here:
Sub abc_Dictionary()
Dim oWS As Worksheet
Dim RangeToSearch As Range
Dim myCell As Range
Dim UniqueDict As Object
Set oWS = Worksheets("Sheet1")
Set RangeToSearch = oWS.Range("B1:B26") 'You can set this dynamically however you wish
Set UniqueDict = CreateObject("Scripting.Dictionary")
'Now we search the range for the given values.
For Each myCell In RangeToSearch
If (myCell.Text = "0" Or myCell.Text = "-2") And Not UniqueDict.exists(oWS.Range("A" & myCell.Row).Text) Then
UniqueDict.Add oWS.Range("A" & myCell.Row).Text, oWS.Range("A" & myCell.Row).Text
End If
Next
'Now we have a dictionary object with the unique values of column a
'So we just iterate and dump into Sheet2
Dim d As Variant
Dim Val As Variant
Dim DestRow As Integer
DestRow = 1 'This is the first row of data we will use on Sheet 2
d = UniqueDict.Items
For Each Val In d
Worksheets("Sheet2").Range("A" & DestRow).Value = Val
DestRow = DestRow + 1
Next
Set UniqueDict = Nothing
Set RangeToSearch = Nothing
Set oWS = Nothing
End Sub
